5 Changes between 0.9.6 and 0.9.6a [xx XXX 2001]
7 *) Fix bug in PKCS#12 key generation routines. This was triggered
8 if a 3DES key was generated with a 0 initial byte. Include
9 PKCS12_BROKEN_KEYGEN compilation option to retain the old
10 (but broken) behaviour.
13 *) Fix memory leaks in err.c: free err_data string if necessary;
14 don't write to the wrong index in ERR_set_error_data.
17 *) Implement ssl23_peek (analogous to ssl23_read), which previously
21 *) Replace rdtsc with _emit statements for VC++ version 5.
22 [Jeremy Cooper <jeremy@baymoo.org>]
24 *) Make it possible to reuse SSLv2 sessions.
27 *) In copy_email() check for >= 0 as a return value for
28 X509_NAME_get_index_by_NID() since 0 is a valid index.
29 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
31 *) Use better test patterns in bntest.
34 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
35 the method-specific "init()" handler. Also clean up ex_data after
36 calling the method-specific "finish()" handler. Previously, this was
37 happening the other way round.
40 *) Avoid coredump with unsupported or invalid public keys by checking if
41 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
42 PKCS7_verify() fails with non detached data.
45 *) Don't use getenv in library functions when run as setuid/setgid.
46 New function OPENSSL_issetugid().
49 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
50 due to incorrect handling of multi-threading:
52 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
54 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
56 3. Count how many times MemCheck_off() has been called so that
57 nested use can be treated correctly. This also avoids
58 inband-signalling in the previous code (which relied on the
59 assumption that thread ID 0 is impossible).
62 *) Add "-rand" option also to s_client and s_server.
65 *) Fix CPU detection on Irix 6.x.
66 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
67 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
69 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
73 *) Use the cached encoding of an X509_NAME structure rather than
74 copying it. This is apparently the reason for the libsafe "errors"
75 but the code is actually correct.
78 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
79 Bleichenbacher's DSA attack.
80 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
81 to be set and top=0 forces the highest bit to be set; top=-1 is new
82 and leaves the highest bit random.
85 *) In the NCONF_...-based implementations for CONF_... queries
86 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
87 a temporary CONF structure with the data component set to NULL
88 (which gives segmentation faults in lh_retrieve).
89 Instead, use NULL for the CONF pointer in CONF_get_string and
90 CONF_get_number (which may use environment variables) and directly
91 return NULL from CONF_get_section.
94 *) Fix potential buffer overrun for EBCDIC.
97 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
98 keyUsage if basicConstraints absent for a CA.
101 *) Make SMIME_write_PKCS7() write mail header values with a format that
102 is more generally accepted (no spaces before the semicolon), since
103 some programs can't parse those values properly otherwise. Also make
104 sure BIO's that break lines after each write do not create invalid
108 *) Make the CRL encoding routines work with empty SEQUENCE OF. The
109 macros previously used would not encode an empty SEQUENCE OF
110 and break the signature.
113 *) Zero the premaster secret after deriving the master secret in
117 *) Add some EVP_add_digest_alias registrations (as found in
118 OpenSSL_add_all_digests()) to SSL_library_init()
119 aka OpenSSL_add_ssl_algorithms(). This provides improved
120 compatibility with peers using X.509 certificates
121 with unconventional AlgorithmIdentifier OIDs.
124 *) Fix for Irix with NO_ASM.
125 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
127 *) ./config script fixes.
128 [Ulf Moeller, Richard Levitte]
130 *) Fix 'openssl passwd -1'.
133 *) Change PKCS12_key_gen_asc() so it can cope with non null
134 terminated strings whose length is passed in the passlen
135 parameter, for example from PEM callbacks. This was done
136 by adding an extra length parameter to asc2uni().
137 [Steve Henson, reported by <oddissey@samsung.co.kr>]
139 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
140 call failed, free the DSA structure.
143 *) Fix to uni2asc() to cope with zero length Unicode strings.
144 These are present in some PKCS#12 files.
147 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
148 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
149 when writing a 32767 byte record.
150 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
152 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
153 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
155 (RSA objects have a reference count access to which is protected
156 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
157 so they are meant to be shared between threads.)
158 [Bodo Moeller, Geoff Thorpe; original patch submitted by
159 "Reddie, Steven" <Steven.Reddie@ca.com>]
161 *) Fix a deadlock in CRYPTO_mem_leaks().
164 *) rand_win.c fix for Borland C.
167 *) BN_rshift bugfix for n == 0.
170 *) Store verify_result within SSL_SESSION also for client side to
171 avoid potential security hole. (Re-used sessions on the client side
172 always resulted in verify_result==X509_V_OK, not using the original
173 result of the server certificate verification.)
176 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
177 SSL3_RT_APPLICATION_DATA, return 0.
178 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
182 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
183 releases, have been re-implemented by renaming the previous
184 implementations of ssl2_read and ssl3_read to ssl2_read_internal
185 and ssl3_read_internal, respectively, and adding 'peek' parameters
186 to them. The new ssl[23]_{read,peek} functions are calls to
187 ssl[23]_read_internal with the 'peek' flag set appropriately.
188 A 'peek' parameter has also been added to ssl3_read_bytes, which
189 does the actual work for ssl3_read_internal.
192 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
193 The previous value, 12, was not always sufficient for BN_mod_exp().
196 *) Fix typo in get_cert_by_subject() in by_dir.c
197 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
199 *) Rework the system to generate shared libraries:
201 - Make note of the expected extension for the shared libraries and
202 if there is a need for symbolic links from for example libcrypto.so.0
203 to libcrypto.so.0.9.7. There is extended info in Configure for
206 - Make as few rebuilds of the shared libraries as possible.
208 - Still avoid linking the OpenSSL programs with the shared libraries.
210 - When installing, install the shared libraries separately from the
214 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
216 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
217 and not in SSL_clear because the latter is also used by the
218 accept/connect functions; previously, the settings made by
219 SSL_set_read_ahead would be lost during the handshake.
220 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
222 *) Correct util/mkdef.pl to be selective about disabled algorithms.
223 Previously, it would create entries for disableed algorithms no
227 *) Added several new manual pages for SSL_* function.
230 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
232 *) In ssl23_get_client_hello, generate an error message when faced
233 with an initial SSL 3.0/TLS record that is too small to contain the
234 first two bytes of the ClientHello message, i.e. client_version.
235 (Note that this is a pathologic case that probably has never happened
236 in real life.) The previous approach was to use the version number
237 from the record header as a substitute; but our protocol choice
238 should not depend on that one because it is not authenticated
239 by the Finished messages.
242 *) More robust randomness gathering functions for Windows.
243 [Jeffrey Altman <jaltman@columbia.edu>]
245 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
246 not set then we don't setup the error code for issuer check errors
247 to avoid possibly overwriting other errors which the callback does
248 handle. If an application does set the flag then we assume it knows
249 what it is doing and can handle the new informational codes
253 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
254 a general "ANY" type, as such it should be able to decode anything
255 including tagged types. However it didn't check the class so it would
256 wrongly interpret tagged types in the same way as their universal
257 counterpart and unknown types were just rejected. Changed so that the
258 tagged and unknown types are handled in the same way as a SEQUENCE:
259 that is the encoding is stored intact. There is also a new type
260 "V_ASN1_OTHER" which is used when the class is not universal, in this
261 case we have no idea what the actual type is so we just lump them all
265 *) On VMS, stdout may very well lead to a file that is written to
266 in a record-oriented fashion. That means that every write() will
267 write a separate record, which will be read separately by the
268 programs trying to read from it. This can be very confusing.
270 The solution is to put a BIO filter in the way that will buffer
271 text until a linefeed is reached, and then write everything a
272 line at a time, so every record written will be an actual line,
273 not chunks of lines and not (usually doesn't happen, but I've
274 seen it once) several lines in one record. BIO_f_linebuffer() is
277 Currently, it's a VMS-only method, because that's where it has
278 been tested well enough.
281 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
282 it can return incorrect results.
283 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
284 but it was in 0.9.6-beta[12].)
287 *) Disable the check for content being present when verifying detached
288 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
289 include zero length content when signing messages.
292 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
293 BIO_ctrl (for BIO pairs).
296 *) Add DSO method for VMS.
299 *) Bug fix: Montgomery multiplication could produce results with the
303 *) Add RPM specification openssl.spec and modify it to build three
304 packages. The default package contains applications, application
305 documentation and run-time libraries. The devel package contains
306 include files, static libraries and function documentation. The
307 doc package contains the contents of the doc directory. The original
308 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
311 *) Add a large number of documentation files for many SSL routines.
312 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
314 *) Add a configuration entry for Sony News 4.
315 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
317 *) Don't set the two most significant bits to one when generating a
318 random number < q in the DSA library.
321 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
322 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
323 the underlying transport is blocking) if a handshake took place.
324 (The default behaviour is needed by applications such as s_client
325 and s_server that use select() to determine when to use SSL_read;
326 but for applications that know in advance when to expect data, it
327 just makes things more complicated.)
330 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
334 *) Add a few more EBCDIC conditionals that make `req' and `x509'
335 work better on such systems.
336 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
338 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
339 Update PKCS12_parse() so it copies the friendlyName and the
340 keyid to the certificates aux info.
343 *) Fix bug in PKCS7_verify() which caused an infinite loop
344 if there was more than one signature.
345 [Sven Uszpelkat <su@celocom.de>]
347 *) Major change in util/mkdef.pl to include extra information
348 about each symbol, as well as presentig variables as well
349 as functions. This change means that there's n more need
350 to rebuild the .num files when some algorithms are excluded.
353 *) Allow the verify time to be set by an application,
354 rather than always using the current time.
357 *) Phase 2 verify code reorganisation. The certificate
358 verify code now looks up an issuer certificate by a
359 number of criteria: subject name, authority key id
360 and key usage. It also verifies self signed certificates
361 by the same criteria. The main comparison function is
362 X509_check_issued() which performs these checks.
364 Lot of changes were necessary in order to support this
365 without completely rewriting the lookup code.
367 Authority and subject key identifier are now cached.
369 The LHASH 'certs' is X509_STORE has now been replaced
370 by a STACK_OF(X509_OBJECT). This is mainly because an
371 LHASH can't store or retrieve multiple objects with
374 As a result various functions (which were all internal
375 use only) have changed to handle the new X509_STORE
376 structure. This will break anything that messed round
377 with X509_STORE internally.
379 The functions X509_STORE_add_cert() now checks for an
380 exact match, rather than just subject name.
382 The X509_STORE API doesn't directly support the retrieval
383 of multiple certificates matching a given criteria, however
384 this can be worked round by performing a lookup first
385 (which will fill the cache with candidate certificates)
386 and then examining the cache for matches. This is probably
387 the best we can do without throwing out X509_LOOKUP
388 entirely (maybe later...).
390 The X509_VERIFY_CTX structure has been enhanced considerably.
392 All certificate lookup operations now go via a get_issuer()
393 callback. Although this currently uses an X509_STORE it
394 can be replaced by custom lookups. This is a simple way
395 to bypass the X509_STORE hackery necessary to make this
396 work and makes it possible to use more efficient techniques
397 in future. A very simple version which uses a simple
398 STACK for its trusted certificate store is also provided
399 using X509_STORE_CTX_trusted_stack().
401 The verify_cb() and verify() callbacks now have equivalents
402 in the X509_STORE_CTX structure.
404 X509_STORE_CTX also has a 'flags' field which can be used
405 to customise the verify behaviour.
408 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
409 excludes S/MIME capabilities.
412 *) When a certificate request is read in keep a copy of the
413 original encoding of the signed data and use it when outputing
414 again. Signatures then use the original encoding rather than
415 a decoded, encoded version which may cause problems if the
416 request is improperly encoded.
419 *) For consistency with other BIO_puts implementations, call
420 buffer_write(b, ...) directly in buffer_puts instead of calling
423 In BIO_puts, increment b->num_write as in BIO_write.
424 [Peter.Sylvester@EdelWeb.fr]
426 *) Fix BN_mul_word for the case where the word is 0. (We have to use
427 BN_zero, we may not return a BIGNUM with an array consisting of
431 *) Avoid calling abort() from within the library when problems are
432 detected, except if preprocessor symbols have been defined
433 (such as REF_CHECK, BN_DEBUG etc.).
436 *) New openssl application 'rsautl'. This utility can be
437 used for low level RSA operations. DER public key
438 BIO/fp routines also added.
441 *) New Configure entry and patches for compiling on QNX 4.
442 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
444 *) A demo state-machine implementation was sponsored by
445 Nuron (http://www.nuron.com/) and is now available in
449 *) New options added to the 'dgst' utility for signature
450 generation and verification.
453 *) Unrecognized PKCS#7 content types are now handled via a
454 catch all ASN1_TYPE structure. This allows unsupported
455 types to be stored as a "blob" and an application can
456 encode and decode it manually.
459 *) Fix various signed/unsigned issues to make a_strex.c
461 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
463 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
464 length if passed a buffer. ASN1_INTEGER_to_BN failed
465 if passed a NULL BN and its argument was negative.
466 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
468 *) Modification to PKCS#7 encoding routines to output definite
469 length encoding. Since currently the whole structures are in
470 memory there's not real point in using indefinite length
471 constructed encoding. However if OpenSSL is compiled with
472 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
475 *) Added BIO_vprintf() and BIO_vsnprintf().
478 *) Added more prefixes to parse for in the the strings written
479 through a logging bio, to cover all the levels that are available
480 through syslog. The prefixes are now:
482 PANIC, EMERG, EMR => LOG_EMERG
483 ALERT, ALR => LOG_ALERT
484 CRIT, CRI => LOG_CRIT
485 ERROR, ERR => LOG_ERR
486 WARNING, WARN, WAR => LOG_WARNING
487 NOTICE, NOTE, NOT => LOG_NOTICE
488 INFO, INF => LOG_INFO
489 DEBUG, DBG => LOG_DEBUG
491 and as before, if none of those prefixes are present at the
492 beginning of the string, LOG_ERR is chosen.
494 On Win32, the LOG_* levels are mapped according to this:
496 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
497 LOG_WARNING => EVENTLOG_WARNING_TYPE
498 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
502 *) Made it possible to reconfigure with just the configuration
503 argument "reconf" or "reconfigure". The command line arguments
504 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
505 and are retrieved from there when reconfiguring.
509 [Assar Westerlund <assar@sics.se>, Richard Levitte]
511 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
514 *) The obj_dat.pl script was messing up the sorting of object
515 names. The reason was that it compared the quoted version
516 of strings as a result "OCSP" > "OCSP Signing" because
517 " > SPACE. Changed script to store unquoted versions of
518 names and add quotes on output. It was also omitting some
519 names from the lookup table if they were given a default
520 value (that is if SN is missing it is given the same
521 value as LN and vice versa), these are now added on the
522 grounds that if an object has a name we should be able to
523 look it up. Finally added warning output when duplicate
524 short or long names are found.
527 *) Changes needed for Tandem NSK.
528 [Scott Uroff <scott@xypro.com>]
530 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
531 RSA_padding_check_SSLv23(), special padding was never detected
532 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
533 version rollback attacks was not effective.
535 In s23_clnt.c, don't use special rollback-attack detection padding
536 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
537 client; similarly, in s23_srvr.c, don't do the rollback check if
538 SSL 2.0 is the only protocol enabled in the server.
541 *) Make it possible to get hexdumps of unprintable data with 'openssl
542 asn1parse'. By implication, the functions ASN1_parse_dump() and
543 BIO_dump_indent() are added.
546 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
547 these print out strings and name structures based on various
548 flags including RFC2253 support and proper handling of
549 multibyte characters. Added options to the 'x509' utility
550 to allow the various flags to be set.
553 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
554 Also change the functions X509_cmp_current_time() and
555 X509_gmtime_adj() work with an ASN1_TIME structure,
556 this will enable certificates using GeneralizedTime in validity
560 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
561 negative public key encodings) on by default,
562 NO_NEG_PUBKEY_BUG can be set to disable it.
565 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
566 content octets. An i2c_ASN1_OBJECT is unnecessary because
567 the encoding can be trivially obtained from the structure.
570 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
571 not read locks (CRYPTO_r_[un]lock).
574 *) A first attempt at creating official support for shared
575 libraries through configuration. I've kept it so the
576 default is static libraries only, and the OpenSSL programs
577 are always statically linked for now, but there are
578 preparations for dynamic linking in place.
579 This has been tested on Linux and True64.
582 *) Randomness polling function for Win9x, as described in:
583 Peter Gutmann, Software Generation of Practically Strong
587 *) Fix so PRNG is seeded in req if using an already existing
591 *) New options to smime application. -inform and -outform
592 allow alternative formats for the S/MIME message including
593 PEM and DER. The -content option allows the content to be
594 specified separately. This should allow things like Netscape
595 form signing output easier to verify.
598 *) Fix the ASN1 encoding of tags using the 'long form'.
601 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
602 STRING types. These convert content octets to and from the
603 underlying type. The actual tag and length octets are
604 already assumed to have been read in and checked. These
605 are needed because all other string types have virtually
606 identical handling apart from the tag. By having versions
607 of the ASN1 functions that just operate on content octets
608 IMPLICIT tagging can be handled properly. It also allows
609 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
610 and ASN1_INTEGER are identical apart from the tag.
613 *) Change the handling of OID objects as follows:
615 - New object identifiers are inserted in objects.txt, following
616 the syntax given in objects.README.
617 - objects.pl is used to process obj_mac.num and create a new
619 - obj_dat.pl is used to create a new obj_dat.h, using the data in
622 This is currently kind of a hack, and the perl code in objects.pl
623 isn't very elegant, but it works as I intended. The simplest way
624 to check that it worked correctly is to look in obj_dat.h and
625 check the array nid_objs and make sure the objects haven't moved
626 around (this is important!). Additions are OK, as well as
627 consistent name changes.
630 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
633 *) Addition of the command line parameter '-rand file' to 'openssl req'.
634 The given file adds to whatever has already been seeded into the
635 random pool through the RANDFILE configuration file option or
636 environment variable, or the default random state file.
639 *) mkstack.pl now sorts each macro group into lexical order.
640 Previously the output order depended on the order the files
641 appeared in the directory, resulting in needless rewriting
645 *) Patches to make OpenSSL compile under Win32 again. Mostly
646 work arounds for the VC++ problem that it treats func() as
647 func(void). Also stripped out the parts of mkdef.pl that
648 added extra typesafe functions: these no longer exist.
651 *) Reorganisation of the stack code. The macros are now all
652 collected in safestack.h . Each macro is defined in terms of
653 a "stack macro" of the form SKM_<name>(type, a, b). The
654 DEBUG_SAFESTACK is now handled in terms of function casts,
655 this has the advantage of retaining type safety without the
656 use of additional functions. If DEBUG_SAFESTACK is not defined
657 then the non typesafe macros are used instead. Also modified the
658 mkstack.pl script to handle the new form. Needs testing to see
659 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
660 the default if no major problems. Similar behaviour for ASN1_SET_OF
664 *) When some versions of IIS use the 'NET' form of private key the
665 key derivation algorithm is different. Normally MD5(password) is
666 used as a 128 bit RC4 key. In the modified case
667 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
668 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
669 as the old Netscape_RSA functions except they have an additional
670 'sgckey' parameter which uses the modified algorithm. Also added
671 an -sgckey command line option to the rsa utility. Thanks to
672 Adrian Peck <bertie@ncipher.com> for posting details of the modified
673 algorithm to openssl-dev.
676 *) The evp_local.h macros were using 'c.##kname' which resulted in
677 invalid expansion on some systems (SCO 5.0.5 for example).
678 Corrected to 'c.kname'.
679 [Phillip Porch <root@theporch.com>]
681 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
682 a STACK of email addresses from a certificate or request, these look
683 in the subject name and the subject alternative name extensions and
684 omit any duplicate addresses.
687 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
688 This makes DSA verification about 2 % faster.
691 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
692 (meaning that now 2^5 values will be precomputed, which is only 4 KB
693 plus overhead for 1024 bit moduli).
694 This makes exponentiations about 0.5 % faster for 1024 bit
695 exponents (as measured by "openssl speed rsa2048").
698 *) Rename memory handling macros to avoid conflicts with other
700 Malloc => OPENSSL_malloc
701 Malloc_locked => OPENSSL_malloc_locked
702 Realloc => OPENSSL_realloc
706 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
707 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
711 [John Jarvie <jjarvie@newsguy.com>]
713 *) The type-safe stack code has been rejigged. It is now only compiled
714 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
715 by default all type-specific stack functions are "#define"d back to
716 standard stack functions. This results in more streamlined output
717 but retains the type-safety checking possibilities of the original
721 *) The STACK code has been cleaned up, and certain type declarations
722 that didn't make a lot of sense have been brought in line. This has
723 also involved a cleanup of sorts in safestack.h to more correctly
724 map type-safe stack functions onto their plain stack counterparts.
725 This work has also resulted in a variety of "const"ifications of
726 lots of the code, especially "_cmp" operations which should normally
727 be prototyped with "const" parameters anyway.
730 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
731 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
732 (The PRNG state consists of two parts, the large pool 'state' and 'md',
733 where all of 'md' is used each time the PRNG is used, but 'state'
734 is used only indexed by a cyclic counter. As entropy may not be
735 well distributed from the beginning, 'md' is important as a
736 chaining variable. However, the output function chains only half
737 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
738 all of 'md', and seeding with STATE_SIZE dummy bytes will result
739 in all of 'state' being rewritten, with the new values depending
740 on virtually all of 'md'. This overcomes the 80 bit limitation.)
743 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
744 the handshake is continued after ssl_verify_cert_chain();
745 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
746 can lead to 'unexplainable' connection aborts later.
747 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
749 *) Major EVP API cipher revision.
750 Add hooks for extra EVP features. This allows various cipher
751 parameters to be set in the EVP interface. Support added for variable
752 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
753 setting of RC2 and RC5 parameters.
755 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
758 Remove lots of duplicated code from the EVP library. For example *every*
759 cipher init() function handles the 'iv' in the same way according to the
760 cipher mode. They also all do nothing if the 'key' parameter is NULL and
761 for CFB and OFB modes they zero ctx->num.
763 New functionality allows removal of S/MIME code RC2 hack.
765 Most of the routines have the same form and so can be declared in terms
768 By shifting this to the top level EVP_CipherInit() it can be removed from
769 all individual ciphers. If the cipher wants to handle IVs or keys
770 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
773 Change lots of functions like EVP_EncryptUpdate() to now return a
774 value: although software versions of the algorithms cannot fail
775 any installed hardware versions can.
778 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
779 this option is set, tolerate broken clients that send the negotiated
780 protocol version number instead of the requested protocol version
784 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
785 i.e. non-zero for export ciphersuites, zero otherwise.
786 Previous versions had this flag inverted, inconsistent with
787 rsa_tmp_cb (..._TMP_RSA_CB).
788 [Bodo Moeller; problem reported by Amit Chopra]
790 *) Add missing DSA library text string. Work around for some IIS
791 key files with invalid SEQUENCE encoding.
794 *) Add a document (doc/standards.txt) that list all kinds of standards
795 and so on that are implemented in OpenSSL.
798 *) Enhance c_rehash script. Old version would mishandle certificates
799 with the same subject name hash and wouldn't handle CRLs at all.
800 Added -fingerprint option to crl utility, to support new c_rehash
804 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
807 *) Fix for SSL server purpose checking. Server checking was
808 rejecting certificates which had extended key usage present
809 but no ssl client purpose.
810 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
812 *) Make PKCS#12 code work with no password. The PKCS#12 spec
813 is a little unclear about how a blank password is handled.
814 Since the password in encoded as a BMPString with terminating
815 double NULL a zero length password would end up as just the
816 double NULL. However no password at all is different and is
817 handled differently in the PKCS#12 key generation code. NS
818 treats a blank password as zero length. MSIE treats it as no
819 password on export: but it will try both on import. We now do
820 the same: PKCS12_parse() tries zero length and no password if
821 the password is set to "" or NULL (NULL is now a valid password:
822 it wasn't before) as does the pkcs12 application.
825 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
826 perror when PEM_read_bio_X509_REQ fails, the error message must
827 be obtained from the error queue.
830 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
831 it in ERR_remove_state if appropriate, and change ERR_get_state
832 accordingly to avoid race conditions (this is necessary because
833 thread_hash is no longer constant once set).
836 *) Bugfix for linux-elf makefile.one.
839 *) RSA_get_default_method() will now cause a default
840 RSA_METHOD to be chosen if one doesn't exist already.
841 Previously this was only set during a call to RSA_new()
842 or RSA_new_method(NULL) meaning it was possible for
843 RSA_get_default_method() to return NULL.
846 *) Added native name translation to the existing DSO code
847 that will convert (if the flag to do so is set) filenames
848 that are sufficiently small and have no path information
849 into a canonical native form. Eg. "blah" converted to
850 "libblah.so" or "blah.dll" etc.
853 *) New function ERR_error_string_n(e, buf, len) which is like
854 ERR_error_string(e, buf), but writes at most 'len' bytes
855 including the 0 terminator. For ERR_error_string_n, 'buf'
857 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
859 *) CONF library reworked to become more general. A new CONF
860 configuration file reader "class" is implemented as well as a
861 new functions (NCONF_*, for "New CONF") to handle it. The now
862 old CONF_* functions are still there, but are reimplemented to
863 work in terms of the new functions. Also, a set of functions
864 to handle the internal storage of the configuration data is
865 provided to make it easier to write new configuration file
866 reader "classes" (I can definitely see something reading a
867 configuration file in XML format, for example), called _CONF_*,
868 or "the configuration storage API"...
870 The new configuration file reading functions are:
872 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
873 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
875 NCONF_default, NCONF_WIN32
877 NCONF_dump_fp, NCONF_dump_bio
879 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
880 NCONF_new creates a new CONF object. This works in the same way
881 as other interfaces in OpenSSL, like the BIO interface.
882 NCONF_dump_* dump the internal storage of the configuration file,
883 which is useful for debugging. All other functions take the same
884 arguments as the old CONF_* functions wth the exception of the
885 first that must be a `CONF *' instead of a `LHASH *'.
887 To make it easer to use the new classes with the old CONF_* functions,
888 the function CONF_set_default_method is provided.
891 *) Add '-tls1' option to 'openssl ciphers', which was already
892 mentioned in the documentation but had not been implemented.
893 (This option is not yet really useful because even the additional
894 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
897 *) Initial DSO code added into libcrypto for letting OpenSSL (and
898 OpenSSL-based applications) load shared libraries and bind to
899 them in a portable way.
900 [Geoff Thorpe, with contributions from Richard Levitte]
902 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
904 *) Make sure _lrotl and _lrotr are only used with MSVC.
906 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
907 (the default implementation of RAND_status).
909 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
910 to '-clrext' (= clear extensions), as intended and documented.
911 [Bodo Moeller; inconsistency pointed out by Michael Attili
914 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
915 was larger than the MD block size.
916 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
918 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
919 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
920 using the passed key: if the passed key was a private key the result
921 of X509_print(), for example, would be to print out all the private key
925 *) des_quad_cksum() byte order bug fix.
926 [Ulf Möller, using the problem description in krb4-0.9.7, where
927 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
929 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
931 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
933 *) For easily testing in shell scripts whether some command
934 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
935 returns with exit code 0 iff no command of the given name is available.
936 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
937 the output goes to stdout and nothing is printed to stderr.
938 Additional arguments are always ignored.
940 Since for each cipher there is a command of the same name,
941 the 'no-cipher' compilation switches can be tested this way.
943 ('openssl no-XXX' is not able to detect pseudo-commands such
944 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
947 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
950 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
951 is set; it will be thrown away anyway because each handshake creates
953 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
954 to parameters -- in previous versions (since OpenSSL 0.9.3) the
955 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
956 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
959 *) New s_client option -ign_eof: EOF at stdin is ignored, and
960 'Q' and 'R' lose their special meanings (quit/renegotiate).
961 This is part of what -quiet does; unlike -quiet, -ign_eof
962 does not suppress any output.
965 *) Add compatibility options to the purpose and trust code. The
966 purpose X509_PURPOSE_ANY is "any purpose" which automatically
967 accepts a certificate or CA, this was the previous behaviour,
968 with all the associated security issues.
970 X509_TRUST_COMPAT is the old trust behaviour: only and
971 automatically trust self signed roots in certificate store. A
972 new trust setting X509_TRUST_DEFAULT is used to specify that
973 a purpose has no associated trust setting and it should instead
974 use the value in the default purpose.
977 *) Fix the PKCS#8 DSA private key code so it decodes keys again
978 and fix a memory leak.
981 *) In util/mkerr.pl (which implements 'make errors'), preserve
982 reason strings from the previous version of the .c file, as
983 the default to have only downcase letters (and digits) in
984 automatically generated reasons codes is not always appropriate.
987 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
988 using strerror. Previously, ERR_reason_error_string() returned
989 library names as reason strings for SYSerr; but SYSerr is a special
990 case where small numbers are errno values, not library numbers.
993 *) Add '-dsaparam' option to 'openssl dhparam' application. This
994 converts DSA parameters into DH parameters. (When creating parameters,
995 DSA_generate_parameters is used.)
998 *) Include 'length' (recommended exponent length) in C code generated
999 by 'openssl dhparam -C'.
1002 *) The second argument to set_label in perlasm was already being used
1003 so couldn't be used as a "file scope" flag. Moved to third argument
1007 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
1008 instead of RAND_bytes for encryption IVs and salts.
1011 *) Include RAND_status() into RAND_METHOD instead of implementing
1012 it only for md_rand.c Otherwise replacing the PRNG by calling
1013 RAND_set_rand_method would be impossible.
1016 *) Don't let DSA_generate_key() enter an infinite loop if the random
1017 number generation fails.
1020 *) New 'rand' application for creating pseudo-random output.
1023 *) Added configuration support for Linux/IA64
1024 [Rolf Haberrecker <rolf@suse.de>]
1026 *) Assembler module support for Mingw32.
1029 *) Shared library support for HPUX (in shlib/).
1030 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
1032 *) Shared library support for Solaris gcc.
1033 [Lutz Behnke <behnke@trustcenter.de>]
1035 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
1037 *) PKCS7_encrypt() was adding text MIME headers twice because they
1038 were added manually and by SMIME_crlf_copy().
1041 *) In bntest.c don't call BN_rand with zero bits argument.
1042 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
1044 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
1045 case was implemented. This caused BN_div_recp() to fail occasionally.
1048 *) Add an optional second argument to the set_label() in the perl
1049 assembly language builder. If this argument exists and is set
1050 to 1 it signals that the assembler should use a symbol whose
1051 scope is the entire file, not just the current function. This
1052 is needed with MASM which uses the format label:: for this scope.
1053 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
1055 *) Change the ASN1 types so they are typedefs by default. Before
1056 almost all types were #define'd to ASN1_STRING which was causing
1057 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
1061 *) Change names of new functions to the new get1/get0 naming
1062 convention: After 'get1', the caller owns a reference count
1063 and has to call ..._free; 'get0' returns a pointer to some
1064 data structure without incrementing reference counters.
1065 (Some of the existing 'get' functions increment a reference
1066 counter, some don't.)
1067 Similarly, 'set1' and 'add1' functions increase reference
1068 counters or duplicate objects.
1071 *) Allow for the possibility of temp RSA key generation failure:
1072 the code used to assume it always worked and crashed on failure.
1075 *) Fix potential buffer overrun problem in BIO_printf().
1076 [Ulf Möller, using public domain code by Patrick Powell; problem
1077 pointed out by David Sacerdote <das33@cornell.edu>]
1079 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
1080 RAND_egd() and RAND_status(). In the command line application,
1081 the EGD socket can be specified like a seed file using RANDFILE
1085 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
1086 Some CAs (e.g. Verisign) distribute certificates in this form.
1089 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
1090 list to exclude them. This means that no special compilation option
1091 is needed to use anonymous DH: it just needs to be included in the
1095 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
1096 EVP_MD_type. The old functionality is available in a new macro called
1097 EVP_MD_md(). Change code that uses it and update docs.
1100 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
1101 where the 'void *' argument is replaced by a function pointer argument.
1102 Previously 'void *' was abused to point to functions, which works on
1103 many platforms, but is not correct. As these functions are usually
1104 called by macros defined in OpenSSL header files, most source code
1105 should work without changes.
1108 *) <openssl/opensslconf.h> (which is created by Configure) now contains
1109 sections with information on -D... compiler switches used for
1110 compiling the library so that applications can see them. To enable
1111 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
1112 must be defined. E.g.,
1113 #define OPENSSL_ALGORITHM_DEFINES
1114 #include <openssl/opensslconf.h>
1115 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
1116 [Richard Levitte, Ulf and Bodo Möller]
1118 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
1122 *) Change the 'other' type in certificate aux info to a STACK_OF
1123 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
1124 the required ASN1 format: arbitrary types determined by an OID.
1127 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
1128 argument to 'req'. This is not because the function is newer or
1129 better than others it just uses the work 'NEW' in the certificate
1130 request header lines. Some software needs this.
1133 *) Reorganise password command line arguments: now passwords can be
1134 obtained from various sources. Delete the PEM_cb function and make
1135 it the default behaviour: i.e. if the callback is NULL and the
1136 usrdata argument is not NULL interpret it as a null terminated pass
1137 phrase. If usrdata and the callback are NULL then the pass phrase
1138 is prompted for as usual.
1141 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
1142 the support is automatically enabled. The resulting binaries will
1143 autodetect the card and use it if present.
1144 [Ben Laurie and Compaq Inc.]
1146 *) Work around for Netscape hang bug. This sends certificate request
1147 and server done in one record. Since this is perfectly legal in the
1148 SSL/TLS protocol it isn't a "bug" option and is on by default. See
1149 the bugs/SSLv3 entry for more info.
1152 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
1155 *) Add -rand argument to smime and pkcs12 applications and read/write
1159 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
1162 *) Add command line password options to the remaining applications.
1165 *) Bug fix for BN_div_recp() for numerators with an even number of
1169 *) More tests in bntest.c, and changed test_bn output.
1172 *) ./config recognizes MacOS X now.
1175 *) Bug fix for BN_div() when the first words of num and divsor are
1176 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
1179 *) Add support for various broken PKCS#8 formats, and command line
1180 options to produce them.
1183 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
1184 get temporary BIGNUMs from a BN_CTX.
1187 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
1191 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
1192 include a #define from the old name to the new. The original intent
1193 was that statically linked binaries could for example just call
1194 SSLeay_add_all_ciphers() to just add ciphers to the table and not
1195 link with digests. This never worked becayse SSLeay_add_all_digests()
1196 and SSLeay_add_all_ciphers() were in the same source file so calling
1197 one would link with the other. They are now in separate source files.
1200 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
1203 *) Use a less unusual form of the Miller-Rabin primality test (it used
1204 a binary algorithm for exponentiation integrated into the Miller-Rabin
1205 loop, our standard modexp algorithms are faster).
1208 *) Support for the EBCDIC character set completed.
1209 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
1211 *) Source code cleanups: use const where appropriate, eliminate casts,
1212 use void * instead of char * in lhash.
1215 *) Bugfix: ssl3_send_server_key_exchange was not restartable
1216 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
1217 this the server could overwrite ephemeral keys that the client
1221 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
1222 using 50 iterations of the Rabin-Miller test.
1224 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
1225 iterations of the Rabin-Miller test as required by the appendix
1226 to FIPS PUB 186[-1]) instead of DSA_is_prime.
1227 As BN_is_prime_fasttest includes trial division, DSA parameter
1228 generation becomes much faster.
1230 This implies a change for the callback functions in DSA_is_prime
1231 and DSA_generate_parameters: The callback function is called once
1232 for each positive witness in the Rabin-Miller test, not just
1233 occasionally in the inner loop; and the parameters to the
1234 callback function now provide an iteration count for the outer
1235 loop rather than for the current invocation of the inner loop.
1236 DSA_generate_parameters additionally can call the callback
1237 function with an 'iteration count' of -1, meaning that a
1238 candidate has passed the trial division test (when q is generated
1239 from an application-provided seed, trial division is skipped).
1242 *) New function BN_is_prime_fasttest that optionally does trial
1243 division before starting the Rabin-Miller test and has
1244 an additional BN_CTX * argument (whereas BN_is_prime always
1245 has to allocate at least one BN_CTX).
1246 'callback(1, -1, cb_arg)' is called when a number has passed the
1247 trial division stage.
1250 *) Fix for bug in CRL encoding. The validity dates weren't being handled
1254 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
1257 *) New function BN_pseudo_rand().
1260 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
1261 bignum version of BN_from_montgomery() with the working code from
1262 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
1266 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
1267 made it impossible to use the same SSL_SESSION data structure in
1268 SSL2 clients in multiple threads.
1271 *) The return value of RAND_load_file() no longer counts bytes obtained
1272 by stat(). RAND_load_file(..., -1) is new and uses the complete file
1273 to seed the PRNG (previously an explicit byte count was required).
1274 [Ulf Möller, Bodo Möller]
1276 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
1277 used (char *) instead of (void *) and had casts all over the place.
1280 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
1283 *) Retain source code compatibility for BN_prime_checks macro:
1284 BN_is_prime(..., BN_prime_checks, ...) now uses
1285 BN_prime_checks_for_size to determine the appropriate number of
1286 Rabin-Miller iterations.
1289 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
1290 DH_CHECK_P_NOT_SAFE_PRIME.
1291 (Check if this is true? OpenPGP calls them "strong".)
1294 *) Merge the functionality of "dh" and "gendh" programs into a new program
1295 "dhparam". The old programs are retained for now but will handle DH keys
1296 (instead of parameters) in future.
1299 *) Make the ciphers, s_server and s_client programs check the return values
1300 when a new cipher list is set.
1303 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
1304 ciphers. Before when the 56bit ciphers were enabled the sorting was
1307 The syntax for the cipher sorting has been extended to support sorting by
1308 cipher-strength (using the strength_bits hard coded in the tables).
1309 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
1311 Fix a bug in the cipher-command parser: when supplying a cipher command
1312 string with an "undefined" symbol (neither command nor alphanumeric
1313 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
1314 an error is flagged.
1316 Due to the strength-sorting extension, the code of the
1317 ssl_create_cipher_list() function was completely rearranged. I hope that
1318 the readability was also increased :-)
1319 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1321 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
1322 for the first serial number and places 2 in the serial number file. This
1323 avoids problems when the root CA is created with serial number zero and
1324 the first user certificate has the same issuer name and serial number
1328 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
1329 the new code. Add documentation for this stuff.
1332 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
1333 X509_*() to X509at_*() on the grounds that they don't handle X509
1334 structures and behave in an analagous way to the X509v3 functions:
1335 they shouldn't be called directly but wrapper functions should be used
1338 So we also now have some wrapper functions that call the X509at functions
1339 when passed certificate requests. (TO DO: similar things can be done with
1340 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
1341 things. Some of these need some d2i or i2d and print functionality
1342 because they handle more complex structures.)
1345 *) Add missing #ifndefs that caused missing symbols when building libssl
1346 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
1347 NO_RSA in ssl/s2*.c.
1348 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
1350 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
1351 has a return value which indicates the quality of the random data
1352 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
1353 error queue. New function RAND_pseudo_bytes() generates output that is
1354 guaranteed to be unique but not unpredictable. RAND_add is like
1355 RAND_seed, but takes an extra argument for an entropy estimate
1356 (RAND_seed always assumes full entropy).
1359 *) Do more iterations of Rabin-Miller probable prime test (specifically,
1360 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
1361 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
1362 in crypto/bn/bn_prime.c for the complete table). This guarantees a
1363 false-positive rate of at most 2^-80 for random input.
1366 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
1369 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
1370 in the 0.9.5 release), this returns the chain
1371 from an X509_CTX structure with a dup of the stack and all
1372 the X509 reference counts upped: so the stack will exist
1373 after X509_CTX_cleanup() has been called. Modify pkcs12.c
1376 Also make SSL_SESSION_print() print out the verify return
1380 *) Add manpage for the pkcs12 command. Also change the default
1381 behaviour so MAC iteration counts are used unless the new
1382 -nomaciter option is used. This improves file security and
1383 only older versions of MSIE (4.0 for example) need it.
1386 *) Honor the no-xxx Configure options when creating .DEF files.
1389 *) Add PKCS#10 attributes to field table: challengePassword,
1390 unstructuredName and unstructuredAddress. These are taken from
1391 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
1392 international characters are used.
1394 More changes to X509_ATTRIBUTE code: allow the setting of types
1395 based on strings. Remove the 'loc' parameter when adding
1396 attributes because these will be a SET OF encoding which is sorted
1400 *) Initial changes to the 'req' utility to allow request generation
1401 automation. This will allow an application to just generate a template
1402 file containing all the field values and have req construct the
1405 Initial support for X509_ATTRIBUTE handling. Stacks of these are
1406 used all over the place including certificate requests and PKCS#7
1407 structures. They are currently handled manually where necessary with
1408 some primitive wrappers for PKCS#7. The new functions behave in a
1409 manner analogous to the X509 extension functions: they allow
1410 attributes to be looked up by NID and added.
1412 Later something similar to the X509V3 code would be desirable to
1413 automatically handle the encoding, decoding and printing of the
1414 more complex types. The string types like challengePassword can
1415 be handled by the string table functions.
1417 Also modified the multi byte string table handling. Now there is
1418 a 'global mask' which masks out certain types. The table itself
1419 can use the flag STABLE_NO_MASK to ignore the mask setting: this
1420 is useful when for example there is only one permissible type
1421 (as in countryName) and using the mask might result in no valid
1425 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
1426 SSL_get_peer_finished to allow applications to obtain the latest
1427 Finished messages sent to the peer or expected from the peer,
1428 respectively. (SSL_get_peer_finished is usually the Finished message
1429 actually received from the peer, otherwise the protocol will be aborted.)
1431 As the Finished message are message digests of the complete handshake
1432 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
1433 be used for external authentication procedures when the authentication
1434 provided by SSL/TLS is not desired or is not enough.
1437 *) Enhanced support for Alpha Linux is added. Now ./config checks if
1438 the host supports BWX extension and if Compaq C is present on the
1439 $PATH. Just exploiting of the BWX extension results in 20-30%
1440 performance kick for some algorithms, e.g. DES and RC4 to mention
1441 a couple. Compaq C in turn generates ~20% faster code for MD5 and
1445 *) Add support for MS "fast SGC". This is arguably a violation of the
1446 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
1447 weak crypto and after checking the certificate is SGC a second one
1448 with strong crypto. MS SGC stops the first handshake after receiving
1449 the server certificate message and sends a second client hello. Since
1450 a server will typically do all the time consuming operations before
1451 expecting any further messages from the client (server key exchange
1452 is the most expensive) there is little difference between the two.
1454 To get OpenSSL to support MS SGC we have to permit a second client
1455 hello message after we have sent server done. In addition we have to
1456 reset the MAC if we do get this second client hello.
1459 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
1460 if a DER encoded private key is RSA or DSA traditional format. Changed
1461 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
1462 format DER encoded private key. Newer code should use PKCS#8 format which
1463 has the key type encoded in the ASN1 structure. Added DER private key
1464 support to pkcs8 application.
1467 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
1468 ciphersuites has been selected (as required by the SSL 3/TLS 1
1469 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
1470 is set, we interpret this as a request to violate the specification
1471 (the worst that can happen is a handshake failure, and 'correct'
1472 behaviour would result in a handshake failure anyway).
1475 *) In SSL_CTX_add_session, take into account that there might be multiple
1476 SSL_SESSION structures with the same session ID (e.g. when two threads
1477 concurrently obtain them from an external cache).
1478 The internal cache can handle only one SSL_SESSION with a given ID,
1479 so if there's a conflict, we now throw out the old one to achieve
1483 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
1484 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
1485 some routines that use cipher OIDs: some ciphers do not have OIDs
1486 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
1490 *) Simplify the trust setting structure and code. Now we just have
1491 two sequences of OIDs for trusted and rejected settings. These will
1492 typically have values the same as the extended key usage extension
1493 and any application specific purposes.
1495 The trust checking code now has a default behaviour: it will just
1496 check for an object with the same NID as the passed id. Functions can
1497 be provided to override either the default behaviour or the behaviour
1498 for a given id. SSL client, server and email already have functions
1499 in place for compatibility: they check the NID and also return "trusted"
1500 if the certificate is self signed.
1503 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
1504 traditional format into an EVP_PKEY structure.
1507 *) Add a password callback function PEM_cb() which either prompts for
1508 a password if usr_data is NULL or otherwise assumes it is a null
1509 terminated password. Allow passwords to be passed on command line
1510 environment or config files in a few more utilities.
1513 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
1514 keys. Add some short names for PKCS#8 PBE algorithms and allow them
1515 to be specified on the command line for the pkcs8 and pkcs12 utilities.
1516 Update documentation.
1519 *) Support for ASN1 "NULL" type. This could be handled before by using
1520 ASN1_TYPE but there wasn't any function that would try to read a NULL
1521 and produce an error if it couldn't. For compatibility we also have
1522 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
1523 don't allocate anything because they don't need to.
1526 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
1528 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
1530 *) Rebuild of the memory allocation routines used by OpenSSL code and
1531 possibly others as well. The purpose is to make an interface that
1532 provide hooks so anyone can build a separate set of allocation and
1533 deallocation routines to be used by OpenSSL, for example memory
1534 pool implementations, or something else, which was previously hard
1535 since Malloc(), Realloc() and Free() were defined as macros having
1536 the values malloc, realloc and free, respectively (except for Win32
1537 compilations). The same is provided for memory debugging code.
1538 OpenSSL already comes with functionality to find memory leaks, but
1539 this gives people a chance to debug other memory problems.
1541 With these changes, a new set of functions and macros have appeared:
1543 CRYPTO_set_mem_debug_functions() [F]
1544 CRYPTO_get_mem_debug_functions() [F]
1545 CRYPTO_dbg_set_options() [F]
1546 CRYPTO_dbg_get_options() [F]
1547 CRYPTO_malloc_debug_init() [M]
1549 The memory debug functions are NULL by default, unless the library
1550 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
1551 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
1552 gives the standard debugging functions that come with OpenSSL) or
1553 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
1554 provided by the library user) must be used. When the standard
1555 debugging functions are used, CRYPTO_dbg_set_options can be used to
1556 request additional information:
1557 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
1558 the CRYPTO_MDEBUG_xxx macro when compiling the library.
1560 Also, things like CRYPTO_set_mem_functions will always give the
1561 expected result (the new set of functions is used for allocation
1562 and deallocation) at all times, regardless of platform and compiler
1565 To finish it up, some functions that were never use in any other
1566 way than through macros have a new API and new semantic:
1569 CRYPTO_dbg_realloc()
1572 All macros of value have retained their old syntax.
1573 [Richard Levitte and Bodo Moeller]
1575 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
1576 ordering of SMIMECapabilities wasn't in "strength order" and there
1577 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
1581 *) Some ASN1 types with illegal zero length encoding (INTEGER,
1582 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
1583 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
1585 *) Merge in my S/MIME library for OpenSSL. This provides a simple
1586 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
1587 functionality to handle multipart/signed properly) and a utility
1588 called 'smime' to call all this stuff. This is based on code I
1589 originally wrote for Celo who have kindly allowed it to be
1590 included in OpenSSL.
1593 *) Add variants des_set_key_checked and des_set_key_unchecked of
1594 des_set_key (aka des_key_sched). Global variable des_check_key
1595 decides which of these is called by des_set_key; this way
1596 des_check_key behaves as it always did, but applications and
1597 the library itself, which was buggy for des_check_key == 1,
1598 have a cleaner way to pick the version they need.
1601 *) New function PKCS12_newpass() which changes the password of a
1605 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
1606 dynamic mix. In both cases the ids can be used as an index into the
1607 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
1608 functions so they accept a list of the field values and the
1609 application doesn't need to directly manipulate the X509_TRUST
1613 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
1617 *) Modify the way the V3 extension code looks up extensions. This now
1618 works in a similar way to the object code: we have some "standard"
1619 extensions in a static table which is searched with OBJ_bsearch()
1620 and the application can add dynamic ones if needed. The file
1621 crypto/x509v3/ext_dat.h now has the info: this file needs to be
1622 updated whenever a new extension is added to the core code and kept
1623 in ext_nid order. There is a simple program 'tabtest.c' which checks
1624 this. New extensions are not added too often so this file can readily
1625 be maintained manually.
1627 There are two big advantages in doing things this way. The extensions
1628 can be looked up immediately and no longer need to be "added" using
1629 X509V3_add_standard_extensions(): this function now does nothing.
1630 [Side note: I get *lots* of email saying the extension code doesn't
1631 work because people forget to call this function]
1632 Also no dynamic allocation is done unless new extensions are added:
1633 so if we don't add custom extensions there is no need to call
1634 X509V3_EXT_cleanup().
1637 *) Modify enc utility's salting as follows: make salting the default. Add a
1638 magic header, so unsalted files fail gracefully instead of just decrypting
1639 to garbage. This is because not salting is a big security hole, so people
1640 should be discouraged from doing it.
1643 *) Fixes and enhancements to the 'x509' utility. It allowed a message
1644 digest to be passed on the command line but it only used this
1645 parameter when signing a certificate. Modified so all relevant
1646 operations are affected by the digest parameter including the
1647 -fingerprint and -x509toreq options. Also -x509toreq choked if a
1648 DSA key was used because it didn't fix the digest.
1651 *) Initial certificate chain verify code. Currently tests the untrusted
1652 certificates for consistency with the verify purpose (which is set
1653 when the X509_STORE_CTX structure is set up) and checks the pathlength.
1655 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
1656 this is because it will reject chains with invalid extensions whereas
1657 every previous version of OpenSSL and SSLeay made no checks at all.
1659 Trust code: checks the root CA for the relevant trust settings. Trust
1660 settings have an initial value consistent with the verify purpose: e.g.
1661 if the verify purpose is for SSL client use it expects the CA to be
1662 trusted for SSL client use. However the default value can be changed to
1663 permit custom trust settings: one example of this would be to only trust
1664 certificates from a specific "secure" set of CAs.
1666 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
1667 which should be used for version portability: especially since the
1668 verify structure is likely to change more often now.
1670 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
1671 to set them. If not set then assume SSL clients will verify SSL servers
1674 Two new options to the verify program: -untrusted allows a set of
1675 untrusted certificates to be passed in and -purpose which sets the
1676 intended purpose of the certificate. If a purpose is set then the
1677 new chain verify code is used to check extension consistency.
1680 *) Support for the authority information access extension.
1683 *) Modify RSA and DSA PEM read routines to transparently handle
1684 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
1685 public keys in a format compatible with certificate
1686 SubjectPublicKeyInfo structures. Unfortunately there were already
1687 functions called *_PublicKey_* which used various odd formats so
1688 these are retained for compatibility: however the DSA variants were
1689 never in a public release so they have been deleted. Changed dsa/rsa
1690 utilities to handle the new format: note no releases ever handled public
1691 keys so we should be OK.
1693 The primary motivation for this change is to avoid the same fiasco
1694 that dogs private keys: there are several incompatible private key
1695 formats some of which are standard and some OpenSSL specific and
1696 require various evil hacks to allow partial transparent handling and
1697 even then it doesn't work with DER formats. Given the option anything
1698 other than PKCS#8 should be dumped: but the other formats have to
1699 stay in the name of compatibility.
1701 With public keys and the benefit of hindsight one standard format
1702 is used which works with EVP_PKEY, RSA or DSA structures: though
1703 it clearly returns an error if you try to read the wrong kind of key.
1705 Added a -pubkey option to the 'x509' utility to output the public key.
1706 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
1707 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
1708 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
1709 that do the same as the EVP_PKEY_assign_*() except they up the
1710 reference count of the added key (they don't "swallow" the
1714 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
1715 CRLs would fail if the file contained no certificates or no CRLs:
1716 added a new function to read in both types and return the number
1717 read: this means that if none are read it will be an error. The
1718 DER versions of the certificate and CRL reader would always fail
1719 because it isn't possible to mix certificates and CRLs in DER format
1720 without choking one or the other routine. Changed this to just read
1721 a certificate: this is the best we can do. Also modified the code
1722 in apps/verify.c to take notice of return codes: it was previously
1723 attempting to read in certificates from NULL pointers and ignoring
1724 any errors: this is one reason why the cert and CRL reader seemed
1725 to work. It doesn't check return codes from the default certificate
1726 routines: these may well fail if the certificates aren't installed.
1729 *) Code to support otherName option in GeneralName.
1732 *) First update to verify code. Change the verify utility
1733 so it warns if it is passed a self signed certificate:
1734 for consistency with the normal behaviour. X509_verify
1735 has been modified to it will now verify a self signed
1736 certificate if *exactly* the same certificate appears
1737 in the store: it was previously impossible to trust a
1738 single self signed certificate. This means that:
1739 openssl verify ss.pem
1740 now gives a warning about a self signed certificate but
1741 openssl verify -CAfile ss.pem ss.pem
1745 *) For servers, store verify_result in SSL_SESSION data structure
1746 (and add it to external session representation).
1747 This is needed when client certificate verifications fails,
1748 but an application-provided verification callback (set by
1749 SSL_CTX_set_cert_verify_callback) allows accepting the session
1750 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
1751 but returns 1): When the session is reused, we have to set
1752 ssl->verify_result to the appropriate error code to avoid
1754 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
1756 *) Fix a bug in the new PKCS#7 code: it didn't consider the
1757 case in PKCS7_dataInit() where the signed PKCS7 structure
1758 didn't contain any existing data because it was being created.
1759 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
1761 *) Add a salt to the key derivation routines in enc.c. This
1762 forms the first 8 bytes of the encrypted file. Also add a
1763 -S option to allow a salt to be input on the command line.
1766 *) New function X509_cmp(). Oddly enough there wasn't a function
1767 to compare two certificates. We do this by working out the SHA1
1768 hash and comparing that. X509_cmp() will be needed by the trust
1772 *) SSL_get1_session() is like SSL_get_session(), but increments
1773 the reference count in the SSL_SESSION returned.
1774 [Geoff Thorpe <geoff@eu.c2.net>]
1776 *) Fix for 'req': it was adding a null to request attributes.
1777 Also change the X509_LOOKUP and X509_INFO code to handle
1778 certificate auxiliary information.
1781 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
1785 *) Add the possibility to add extra information to the memory leak
1786 detecting output, to form tracebacks, showing from where each
1787 allocation was originated: CRYPTO_push_info("constant string") adds
1788 the string plus current file name and line number to a per-thread
1789 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
1790 is like calling CYRPTO_pop_info() until the stack is empty.
1791 Also updated memory leak detection code to be multi-thread-safe.
1794 *) Add options -text and -noout to pkcs7 utility and delete the
1795 encryption options which never did anything. Update docs.
1798 *) Add options to some of the utilities to allow the pass phrase
1799 to be included on either the command line (not recommended on
1800 OSes like Unix) or read from the environment. Update the
1801 manpages and fix a few bugs.
1804 *) Add a few manpages for some of the openssl commands.
1807 *) Fix the -revoke option in ca. It was freeing up memory twice,
1808 leaking and not finding already revoked certificates.
1811 *) Extensive changes to support certificate auxiliary information.
1812 This involves the use of X509_CERT_AUX structure and X509_AUX
1813 functions. An X509_AUX function such as PEM_read_X509_AUX()
1814 can still read in a certificate file in the usual way but it
1815 will also read in any additional "auxiliary information". By
1816 doing things this way a fair degree of compatibility can be
1817 retained: existing certificates can have this information added
1818 using the new 'x509' options.
1820 Current auxiliary information includes an "alias" and some trust
1821 settings. The trust settings will ultimately be used in enhanced
1822 certificate chain verification routines: currently a certificate
1823 can only be trusted if it is self signed and then it is trusted
1827 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
1828 The problem was that one of the replacement routines had not been working
1829 since SSLeay releases. For now the offending routine has been replaced
1830 with non-optimised assembler. Even so, this now gives around 95%
1831 performance improvement for 1024 bit RSA signs.
1834 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
1835 handling. Most clients have the effective key size in bits equal to
1836 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
1837 A few however don't do this and instead use the size of the decrypted key
1838 to determine the RC2 key length and the AlgorithmIdentifier to determine
1839 the effective key length. In this case the effective key length can still
1840 be 40 bits but the key length can be 168 bits for example. This is fixed
1841 by manually forcing an RC2 key into the EVP_PKEY structure because the
1842 EVP code can't currently handle unusual RC2 key sizes: it always assumes
1843 the key length and effective key length are equal.
1846 *) Add a bunch of functions that should simplify the creation of
1847 X509_NAME structures. Now you should be able to do:
1848 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
1849 and have it automatically work out the correct field type and fill in
1850 the structures. The more adventurous can try:
1851 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
1852 and it will (hopefully) work out the correct multibyte encoding.
1855 *) Change the 'req' utility to use the new field handling and multibyte
1856 copy routines. Before the DN field creation was handled in an ad hoc
1857 way in req, ca, and x509 which was rather broken and didn't support
1858 BMPStrings or UTF8Strings. Since some software doesn't implement
1859 BMPStrings or UTF8Strings yet, they can be enabled using the config file
1860 using the dirstring_type option. See the new comment in the default
1861 openssl.cnf for more info.
1864 *) Make crypto/rand/md_rand.c more robust:
1865 - Assure unique random numbers after fork().
1866 - Make sure that concurrent threads access the global counter and
1867 md serializably so that we never lose entropy in them
1868 or use exactly the same state in multiple threads.
1869 Access to the large state is not always serializable because
1870 the additional locking could be a performance killer, and
1871 md should be large enough anyway.
1874 *) New file apps/app_rand.c with commonly needed functionality
1875 for handling the random seed file.
1877 Use the random seed file in some applications that previously did not:
1879 dsaparam -genkey (which also ignored its '-rand' option),
1882 x509 (when signing).
1883 Except on systems with /dev/urandom, it is crucial to have a random
1884 seed file at least for key creation, DSA signing, and for DH exchanges;
1885 for RSA signatures we could do without one.
1887 gendh and gendsa (unlike genrsa) used to read only the first byte
1888 of each file listed in the '-rand' option. The function as previously
1889 found in genrsa is now in app_rand.c and is used by all programs
1890 that support '-rand'.
1893 *) In RAND_write_file, use mode 0600 for creating files;
1894 don't just chmod when it may be too late.
1897 *) Report an error from X509_STORE_load_locations
1898 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
1901 *) New function ASN1_mbstring_copy() this copies a string in either
1902 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
1903 into an ASN1_STRING type. A mask of permissible types is passed
1904 and it chooses the "minimal" type to use or an error if not type
1908 *) Add function equivalents to the various macros in asn1.h. The old
1909 macros are retained with an M_ prefix. Code inside the library can
1910 use the M_ macros. External code (including the openssl utility)
1911 should *NOT* in order to be "shared library friendly".
1914 *) Add various functions that can check a certificate's extensions
1915 to see if it usable for various purposes such as SSL client,
1916 server or S/MIME and CAs of these types. This is currently
1917 VERY EXPERIMENTAL but will ultimately be used for certificate chain
1918 verification. Also added a -purpose flag to x509 utility to
1919 print out all the purposes.
1922 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
1926 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
1927 for, obtain and decode and extension and obtain its critical flag.
1928 This allows all the necessary extension code to be handled in a
1929 single function call.
1932 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
1933 platforms. See crypto/rc4/rc4_enc.c for further details.
1936 *) New -noout option to asn1parse. This causes no output to be produced
1937 its main use is when combined with -strparse and -out to extract data
1938 from a file (which may not be in ASN.1 format).
1941 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
1942 when producing the local key id.
1943 [Richard Levitte <levitte@stacken.kth.se>]
1945 *) New option -dhparam in s_server. This allows a DH parameter file to be
1946 stated explicitly. If it is not stated then it tries the first server
1947 certificate file. The previous behaviour hard coded the filename
1951 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
1952 a public key to be input or output. For example:
1953 openssl rsa -in key.pem -pubout -out pubkey.pem
1954 Also added necessary DSA public key functions to handle this.
1957 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
1958 in the message. This was handled by allowing
1959 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
1960 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
1962 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
1963 to the end of the strings whereas this didn't. This would cause problems
1964 if strings read with d2i_ASN1_bytes() were later modified.
1965 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
1967 *) Fix for base64 decode bug. When a base64 bio reads only one line of
1968 data and it contains EOF it will end up returning an error. This is
1969 caused by input 46 bytes long. The cause is due to the way base64
1970 BIOs find the start of base64 encoded data. They do this by trying a
1971 trial decode on each line until they find one that works. When they
1972 do a flag is set and it starts again knowing it can pass all the
1973 data directly through the decoder. Unfortunately it doesn't reset
1974 the context it uses. This means that if EOF is reached an attempt
1975 is made to pass two EOFs through the context and this causes the
1976 resulting error. This can also cause other problems as well. As is
1977 usual with these problems it takes *ages* to find and the fix is
1978 trivial: move one line.
1979 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
1981 *) Ugly workaround to get s_client and s_server working under Windows. The
1982 old code wouldn't work because it needed to select() on sockets and the
1983 tty (for keypresses and to see if data could be written). Win32 only
1984 supports select() on sockets so we select() with a 1s timeout on the
1985 sockets and then see if any characters are waiting to be read, if none
1986 are present then we retry, we also assume we can always write data to
1987 the tty. This isn't nice because the code then blocks until we've
1988 received a complete line of data and it is effectively polling the
1989 keyboard at 1s intervals: however it's quite a bit better than not
1990 working at all :-) A dedicated Windows application might handle this
1991 with an event loop for example.
1994 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
1995 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
1996 will be called when RSA_sign() and RSA_verify() are used. This is useful
1997 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
1998 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
1999 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
2000 This necessitated the support of an extra signature type NID_md5_sha1
2001 for SSL signatures and modifications to the SSL library to use it instead
2002 of calling RSA_public_decrypt() and RSA_private_encrypt().
2005 *) Add new -verify -CAfile and -CApath options to the crl program, these
2006 will lookup a CRL issuers certificate and verify the signature in a
2007 similar way to the verify program. Tidy up the crl program so it
2008 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
2009 less strict. It will now permit CRL extensions even if it is not
2010 a V2 CRL: this will allow it to tolerate some broken CRLs.
2013 *) Initialize all non-automatic variables each time one of the openssl
2014 sub-programs is started (this is necessary as they may be started
2015 multiple times from the "OpenSSL>" prompt).
2016 [Lennart Bang, Bodo Moeller]
2018 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
2019 removing all other RSA functionality (this is what NO_RSA does). This
2020 is so (for example) those in the US can disable those operations covered
2021 by the RSA patent while allowing storage and parsing of RSA keys and RSA
2025 *) Non-copying interface to BIO pairs.
2026 (still largely untested)
2029 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
2030 ASCII string. This was handled independently in various places before.
2033 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
2034 UTF8 strings a character at a time.
2037 *) Use client_version from client hello to select the protocol
2038 (s23_srvr.c) and for RSA client key exchange verification
2039 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
2042 *) Add various utility functions to handle SPKACs, these were previously
2043 handled by poking round in the structure internals. Added new function
2044 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
2045 print, verify and generate SPKACs. Based on an original idea from
2046 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
2049 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
2052 *) Allow the config file extension section to be overwritten on the
2053 command line. Based on an original idea from Massimiliano Pala
2054 <madwolf@comune.modena.it>. The new option is called -extensions
2055 and can be applied to ca, req and x509. Also -reqexts to override
2056 the request extensions in req and -crlexts to override the crl extensions
2060 *) Add new feature to the SPKAC handling in ca. Now you can include
2061 the same field multiple times by preceding it by "XXXX." for example:
2064 this is the same syntax as used in the req config file.
2067 *) Allow certificate extensions to be added to certificate requests. These
2068 are specified in a 'req_extensions' option of the req section of the
2069 config file. They can be printed out with the -text option to req but
2070 are otherwise ignored at present.
2073 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
2074 data read consists of only the final block it would not decrypted because
2075 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
2076 A misplaced 'break' also meant the decrypted final block might not be
2077 copied until the next read.
2080 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
2081 a few extra parameters to the DH structure: these will be useful if
2082 for example we want the value of 'q' or implement X9.42 DH.
2085 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
2086 provides hooks that allow the default DSA functions or functions on a
2087 "per key" basis to be replaced. This allows hardware acceleration and
2088 hardware key storage to be handled without major modification to the
2089 library. Also added low level modexp hooks and CRYPTO_EX structure and
2090 associated functions.
2093 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
2094 as "read only": it can't be written to and the buffer it points to will
2095 not be freed. Reading from a read only BIO is much more efficient than
2096 a normal memory BIO. This was added because there are several times when
2097 an area of memory needs to be read from a BIO. The previous method was
2098 to create a memory BIO and write the data to it, this results in two
2099 copies of the data and an O(n^2) reading algorithm. There is a new
2100 function BIO_new_mem_buf() which creates a read only memory BIO from
2101 an area of memory. Also modified the PKCS#7 routines to use read only
2105 *) Bugfix: ssl23_get_client_hello did not work properly when called in
2106 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
2107 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
2108 but a retry condition occured while trying to read the rest.
2111 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
2112 NID_pkcs7_encrypted by default: this was wrong since this should almost
2113 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
2114 the encrypted data type: this is a more sensible place to put it and it
2115 allows the PKCS#12 code to be tidied up that duplicated this
2119 *) Changed obj_dat.pl script so it takes its input and output files on
2120 the command line. This should avoid shell escape redirection problems
2124 *) Initial support for certificate extension requests, these are included
2125 in things like Xenroll certificate requests. Included functions to allow
2126 extensions to be obtained and added.
2129 *) -crlf option to s_client and s_server for sending newlines as
2130 CRLF (as required by many protocols).
2133 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
2135 *) Install libRSAglue.a when OpenSSL is built with RSAref.
2136 [Ralf S. Engelschall]
2138 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
2139 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
2141 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
2145 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
2146 DH parameters/keys (q is lost during that conversion, but the resulting
2147 DH parameters contain its length).
2149 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
2150 much faster than DH_generate_parameters (which creates parameters
2151 where p = 2*q + 1), and also the smaller q makes DH computations
2152 much more efficient (160-bit exponentiation instead of 1024-bit
2153 exponentiation); so this provides a convenient way to support DHE
2154 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
2155 utter importance to use
2156 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2158 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2159 when such DH parameters are used, because otherwise small subgroup
2160 attacks may become possible!
2163 *) Avoid memory leak in i2d_DHparams.
2166 *) Allow the -k option to be used more than once in the enc program:
2167 this allows the same encrypted message to be read by multiple recipients.
2170 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
2171 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
2172 it will always use the numerical form of the OID, even if it has a short
2176 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
2177 method only got called if p,q,dmp1,dmq1,iqmp components were present,
2178 otherwise bn_mod_exp was called. In the case of hardware keys for example
2179 no private key components need be present and it might store extra data
2180 in the RSA structure, which cannot be accessed from bn_mod_exp.
2181 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
2182 private key operations.
2185 *) Added support for SPARC Linux.
2188 *) pem_password_cb function type incompatibly changed from
2189 typedef int pem_password_cb(char *buf, int size, int rwflag);
2191 ....(char *buf, int size, int rwflag, void *userdata);
2192 so that applications can pass data to their callbacks:
2193 The PEM[_ASN1]_{read,write}... functions and macros now take an
2194 additional void * argument, which is just handed through whenever
2195 the password callback is called.
2196 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
2198 New function SSL_CTX_set_default_passwd_cb_userdata.
2200 Compatibility note: As many C implementations push function arguments
2201 onto the stack in reverse order, the new library version is likely to
2202 interoperate with programs that have been compiled with the old
2203 pem_password_cb definition (PEM_whatever takes some data that
2204 happens to be on the stack as its last argument, and the callback
2205 just ignores this garbage); but there is no guarantee whatsoever that
2208 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
2209 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
2210 problems not only on Windows, but also on some Unix platforms.
2211 To avoid problematic command lines, these definitions are now in an
2212 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
2213 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
2216 *) MIPS III/IV assembler module is reimplemented.
2219 *) More DES library cleanups: remove references to srand/rand and
2220 delete an unused file.
2223 *) Add support for the the free Netwide assembler (NASM) under Win32,
2224 since not many people have MASM (ml) and it can be hard to obtain.
2225 This is currently experimental but it seems to work OK and pass all
2226 the tests. Check out INSTALL.W32 for info.
2229 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
2230 without temporary keys kept an extra copy of the server key,
2231 and connections with temporary keys did not free everything in case
2235 *) New function RSA_check_key and new openssl rsa option -check
2236 for verifying the consistency of RSA keys.
2237 [Ulf Moeller, Bodo Moeller]
2239 *) Various changes to make Win32 compile work:
2240 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
2241 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
2242 comparison" warnings.
2243 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
2246 *) Add a debugging option to PKCS#5 v2 key generation function: when
2247 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
2248 derived keys are printed to stderr.
2251 *) Copy the flags in ASN1_STRING_dup().
2252 [Roman E. Pavlov <pre@mo.msk.ru>]
2254 *) The x509 application mishandled signing requests containing DSA
2255 keys when the signing key was also DSA and the parameters didn't match.
2257 It was supposed to omit the parameters when they matched the signing key:
2258 the verifying software was then supposed to automatically use the CA's
2259 parameters if they were absent from the end user certificate.
2261 Omitting parameters is no longer recommended. The test was also
2262 the wrong way round! This was probably due to unusual behaviour in
2263 EVP_cmp_parameters() which returns 1 if the parameters match.
2264 This meant that parameters were omitted when they *didn't* match and
2265 the certificate was useless. Certificates signed with 'ca' didn't have
2267 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
2269 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
2270 The interface is as follows:
2271 Applications can use
2272 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
2273 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
2274 "off" is now the default.
2275 The library internally uses
2276 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
2277 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
2278 to disable memory-checking temporarily.
2280 Some inconsistent states that previously were possible (and were
2281 even the default) are now avoided.
2283 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
2284 with each memory chunk allocated; this is occasionally more helpful
2285 than just having a counter.
2287 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
2289 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
2293 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
2294 which largely parallels "options", but is for changing API behaviour,
2295 whereas "options" are about protocol behaviour.
2296 Initial "mode" flags are:
2298 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
2299 a single record has been written.
2300 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
2301 retries use the same buffer location.
2302 (But all of the contents must be
2306 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
2309 *) Fix problems with no-hmac etc.
2310 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
2312 *) New functions RSA_get_default_method(), RSA_set_method() and
2313 RSA_get_method(). These allows replacement of RSA_METHODs without having
2314 to mess around with the internals of an RSA structure.
2317 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
2318 Also really enable memory leak checks in openssl.c and in some
2320 [Chad C. Mulligan, Bodo Moeller]
2322 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
2323 up the length of negative integers. This has now been simplified to just
2324 store the length when it is first determined and use it later, rather
2325 than trying to keep track of where data is copied and updating it to
2327 [Steve Henson, reported by Brien Wheeler
2328 <bwheeler@authentica-security.com>]
2330 *) Add a new function PKCS7_signatureVerify. This allows the verification
2331 of a PKCS#7 signature but with the signing certificate passed to the
2332 function itself. This contrasts with PKCS7_dataVerify which assumes the
2333 certificate is present in the PKCS#7 structure. This isn't always the
2334 case: certificates can be omitted from a PKCS#7 structure and be
2335 distributed by "out of band" means (such as a certificate database).
2338 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
2339 function prototypes in pem.h, also change util/mkdef.pl to add the
2340 necessary function names.
2343 *) mk1mf.pl (used by Windows builds) did not properly read the
2344 options set by Configure in the top level Makefile, and Configure
2345 was not even able to write more than one option correctly.
2346 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
2349 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
2350 file to be loaded from a BIO or FILE pointer. The BIO version will
2351 for example allow memory BIOs to contain config info.
2354 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
2355 Whoever hopes to achieve shared-library compatibility across versions
2356 must use this, not the compile-time macro.
2357 (Exercise 0.9.4: Which is the minimum library version required by
2359 Note: All this applies only to multi-threaded programs, others don't
2363 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
2364 through a BIO pair triggered the default case, i.e.
2365 SSLerr(...,SSL_R_UNKNOWN_STATE).
2368 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
2369 can use the SSL library even if none of the specific BIOs is
2373 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
2374 for the encoded length.
2375 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
2377 *) Add initial documentation of the X509V3 functions.
2380 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
2381 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
2382 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
2383 secure PKCS#8 private key format with a high iteration count.
2386 *) Fix determination of Perl interpreter: A perl or perl5
2387 _directory_ in $PATH was also accepted as the interpreter.
2388 [Ralf S. Engelschall]
2390 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
2391 wrong with it but it was very old and did things like calling
2392 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
2396 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
2397 to use the new extension code.
2400 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
2401 with macros. This should make it easier to change their form, add extra
2402 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
2406 *) Add to configuration table a new entry that can specify an alternative
2407 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
2408 according to Mark Crispin <MRC@Panda.COM>.
2412 *) DES CBC did not update the IV. Weird.
2415 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
2416 Changing the behaviour of the former might break existing programs --
2417 where IV updating is needed, des_ncbc_encrypt can be used.
2420 *) When bntest is run from "make test" it drives bc to check its
2421 calculations, as well as internally checking them. If an internal check
2422 fails, it needs to cause bc to give a non-zero result or make test carries
2423 on without noticing the failure. Fixed.
2426 *) DES library cleanups.
2429 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
2430 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
2431 ciphers. NOTE: although the key derivation function has been verified
2432 against some published test vectors it has not been extensively tested
2433 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
2437 *) Instead of "mkdir -p", which is not fully portable, use new
2438 Perl script "util/mkdir-p.pl".
2441 *) Rewrite the way password based encryption (PBE) is handled. It used to
2442 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
2443 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
2444 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
2445 the 'parameter' field of the AlgorithmIdentifier is passed to the
2446 underlying key generation function so it must do its own ASN1 parsing.
2447 This has also changed the EVP_PBE_CipherInit() function which now has a
2448 'parameter' argument instead of literal salt and iteration count values
2449 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
2452 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
2453 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
2454 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
2455 KEY" because this clashed with PKCS#8 unencrypted string. Since this
2456 value was just used as a "magic string" and not used directly its
2457 value doesn't matter.
2460 *) Introduce some semblance of const correctness to BN. Shame C doesn't
2464 *) "linux-sparc64" configuration (ultrapenguin).
2465 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
2466 "linux-sparc" configuration.
2467 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
2469 *) config now generates no-xxx options for missing ciphers.
2472 *) Support the EBCDIC character set (work in progress).
2473 File ebcdic.c not yet included because it has a different license.
2474 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2476 *) Support BS2000/OSD-POSIX.
2477 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2479 *) Make callbacks for key generation use void * instead of char *.
2482 *) Make S/MIME samples compile (not yet tested).
2485 *) Additional typesafe stacks.
2488 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
2492 Changes between 0.9.3 and 0.9.3a [29 May 1999]
2494 *) New configuration variant "sco5-gcc".
2496 *) Updated some demos.
2497 [Sean O Riordain, Wade Scholine]
2499 *) Add missing BIO_free at exit of pkcs12 application.
2502 *) Fix memory leak in conf.c.
2505 *) Updates for Win32 to assembler version of MD5.
2508 *) Set #! path to perl in apps/der_chop to where we found it
2509 instead of using a fixed path.
2512 *) SHA library changes for irix64-mips4-cc.
2515 *) Improvements for VMS support.
2519 Changes between 0.9.2b and 0.9.3 [24 May 1999]
2521 *) Bignum library bug fix. IRIX 6 passes "make test" now!
2522 This also avoids the problems with SC4.2 and unpatched SC5.
2523 [Andy Polyakov <appro@fy.chalmers.se>]
2525 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
2526 These are required because of the typesafe stack would otherwise break
2527 existing code. If old code used a structure member which used to be STACK
2528 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
2529 sk_num or sk_value it would produce an error because the num, data members
2530 are not present in STACK_OF. Now it just produces a warning. sk_set
2531 replaces the old method of assigning a value to sk_value
2532 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
2533 that does this will no longer work (and should use sk_set instead) but
2534 this could be regarded as a "questionable" behaviour anyway.
2537 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
2538 correctly handle encrypted S/MIME data.
2541 *) Change type of various DES function arguments from des_cblock
2542 (which means, in function argument declarations, pointer to char)
2543 to des_cblock * (meaning pointer to array with 8 char elements),
2544 which allows the compiler to do more typechecking; it was like
2545 that back in SSLeay, but with lots of ugly casts.
2547 Introduce new type const_des_cblock.
2550 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
2551 problems: find RecipientInfo structure that matches recipient certificate
2552 and initialise the ASN1 structures properly based on passed cipher.
2555 *) Belatedly make the BN tests actually check the results.
2558 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
2559 to and from BNs: it was completely broken. New compilation option
2560 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
2561 key elements as negative integers.
2564 *) Reorganize and speed up MD5.
2565 [Andy Polyakov <appro@fy.chalmers.se>]
2568 [Richard Levitte <richard@levitte.org>]
2570 *) New option -out to asn1parse to allow the parsed structure to be
2571 output to a file. This is most useful when combined with the -strparse
2572 option to examine the output of things like OCTET STRINGS.
2575 *) Make SSL library a little more fool-proof by not requiring any longer
2576 that SSL_set_{accept,connect}_state be called before
2577 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
2578 in many applications because usually everything *appeared* to work as
2579 intended anyway -- now it really works as intended).
2582 *) Move openssl.cnf out of lib/.
2585 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
2586 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
2587 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
2588 [Ralf S. Engelschall]
2590 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
2591 handle PKCS#7 enveloped data properly.
2592 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
2594 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
2595 copying pointers. The cert_st handling is changed by this in
2596 various ways (and thus what used to be known as ctx->default_cert
2597 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
2598 any longer when s->cert does not give us what we need).
2599 ssl_cert_instantiate becomes obsolete by this change.
2600 As soon as we've got the new code right (possibly it already is?),
2601 we have solved a couple of bugs of the earlier code where s->cert
2602 was used as if it could not have been shared with other SSL structures.
2604 Note that using the SSL API in certain dirty ways now will result
2605 in different behaviour than observed with earlier library versions:
2606 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
2607 does not influence s as it used to.
2609 In order to clean up things more thoroughly, inside SSL_SESSION
2610 we don't use CERT any longer, but a new structure SESS_CERT
2611 that holds per-session data (if available); currently, this is
2612 the peer's certificate chain and, for clients, the server's certificate
2613 and temporary key. CERT holds only those values that can have
2614 meaningful defaults in an SSL_CTX.
2617 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
2618 from the internal representation. Various PKCS#7 fixes: remove some
2619 evil casts and set the enc_dig_alg field properly based on the signing
2623 *) Allow PKCS#12 password to be set from the command line or the
2624 environment. Let 'ca' get its config file name from the environment
2625 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
2629 *) Allow certificate policies extension to use an IA5STRING for the
2630 organization field. This is contrary to the PKIX definition but
2631 VeriSign uses it and IE5 only recognises this form. Document 'x509'
2635 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
2636 without disallowing inline assembler and the like for non-pedantic builds.
2639 *) Support Borland C++ builder.
2640 [Janez Jere <jj@void.si>, modified by Ulf Möller]
2645 *) SHA-1 cleanups and performance enhancements.
2646 [Andy Polyakov <appro@fy.chalmers.se>]
2648 *) Sparc v8plus assembler for the bignum library.
2649 [Andy Polyakov <appro@fy.chalmers.se>]
2651 *) Accept any -xxx and +xxx compiler options in Configure.
2654 *) Update HPUX configuration.
2657 *) Add missing sk_<type>_unshift() function to safestack.h
2658 [Ralf S. Engelschall]
2660 *) New function SSL_CTX_use_certificate_chain_file that sets the
2661 "extra_cert"s in addition to the certificate. (This makes sense
2662 only for "PEM" format files, as chains as a whole are not
2666 *) Support verify_depth from the SSL API.
2667 x509_vfy.c had what can be considered an off-by-one-error:
2668 Its depth (which was not part of the external interface)
2669 was actually counting the number of certificates in a chain;
2670 now it really counts the depth.
2673 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
2674 instead of X509err, which often resulted in confusing error
2675 messages since the error codes are not globally unique
2676 (e.g. an alleged error in ssl3_accept when a certificate
2677 didn't match the private key).
2679 *) New function SSL_CTX_set_session_id_context that allows to set a default
2680 value (so that you don't need SSL_set_session_id_context for each
2681 connection using the SSL_CTX).
2684 *) OAEP decoding bug fix.
2687 *) Support INSTALL_PREFIX for package builders, as proposed by
2691 *) New Configure options "threads" and "no-threads". For systems
2692 where the proper compiler options are known (currently Solaris
2693 and Linux), "threads" is the default.
2696 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
2699 *) Install various scripts to $(OPENSSLDIR)/misc, not to
2700 $(INSTALLTOP)/bin -- they shouldn't clutter directories
2701 such as /usr/local/bin.
2704 *) "make linux-shared" to build shared libraries.
2705 [Niels Poppe <niels@netbox.org>]
2707 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
2710 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
2711 extension adding in x509 utility.
2714 *) Remove NOPROTO sections and error code comments.
2717 *) Partial rewrite of the DEF file generator to now parse the ANSI
2721 *) New Configure options --prefix=DIR and --openssldir=DIR.
2724 *) Complete rewrite of the error code script(s). It is all now handled
2725 by one script at the top level which handles error code gathering,
2726 header rewriting and C source file generation. It should be much better
2727 than the old method: it now uses a modified version of Ulf's parser to
2728 read the ANSI prototypes in all header files (thus the old K&R definitions
2729 aren't needed for error creation any more) and do a better job of
2730 translating function codes into names. The old 'ASN1 error code imbedded
2731 in a comment' is no longer necessary and it doesn't use .err files which
2732 have now been deleted. Also the error code call doesn't have to appear all
2733 on one line (which resulted in some large lines...).
2736 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
2739 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
2740 0 (which usually indicates a closed connection), but continue reading.
2743 *) Fix some race conditions.
2746 *) Add support for CRL distribution points extension. Add Certificate
2747 Policies and CRL distribution points documentation.
2750 *) Move the autogenerated header file parts to crypto/opensslconf.h.
2753 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
2754 8 of keying material. Merlin has also confirmed interop with this fix
2755 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
2756 [Merlin Hughes <merlin@baltimore.ie>]
2758 *) Fix lots of warnings.
2759 [Richard Levitte <levitte@stacken.kth.se>]
2761 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
2762 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
2763 [Richard Levitte <levitte@stacken.kth.se>]
2765 *) Fix problems with sizeof(long) == 8.
2766 [Andy Polyakov <appro@fy.chalmers.se>]
2768 *) Change functions to ANSI C.
2771 *) Fix typos in error codes.
2772 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
2774 *) Remove defunct assembler files from Configure.
2777 *) SPARC v8 assembler BIGNUM implementation.
2778 [Andy Polyakov <appro@fy.chalmers.se>]
2780 *) Support for Certificate Policies extension: both print and set.
2781 Various additions to support the r2i method this uses.
2784 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
2785 return a const string when you are expecting an allocated buffer.
2788 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
2789 types DirectoryString and DisplayText.
2792 *) Add code to allow r2i extensions to access the configuration database,
2793 add an LHASH database driver and add several ctx helper functions.
2796 *) Fix an evil bug in bn_expand2() which caused various BN functions to
2797 fail when they extended the size of a BIGNUM.
2800 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
2801 support typesafe stack.
2804 *) Fix typo in SSL_[gs]et_options().
2805 [Nils Frostberg <nils@medcom.se>]
2807 *) Delete various functions and files that belonged to the (now obsolete)
2808 old X509V3 handling code.
2811 *) New Configure option "rsaref".
2814 *) Don't auto-generate pem.h.
2817 *) Introduce type-safe ASN.1 SETs.
2820 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
2821 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
2823 *) Introduce type-safe STACKs. This will almost certainly break lots of code
2824 that links with OpenSSL (well at least cause lots of warnings), but fear
2825 not: the conversion is trivial, and it eliminates loads of evil casts. A
2826 few STACKed things have been converted already. Feel free to convert more.
2827 In the fullness of time, I'll do away with the STACK type altogether.
2830 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
2831 specified in <certfile> by updating the entry in the index.txt file.
2832 This way one no longer has to edit the index.txt file manually for
2833 revoking a certificate. The -revoke option does the gory details now.
2834 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
2836 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
2837 `-text' option at all and this way the `-noout -text' combination was
2838 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
2839 [Ralf S. Engelschall]
2841 *) Make sure a corresponding plain text error message exists for the
2842 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
2843 verify callback function determined that a certificate was revoked.
2844 [Ralf S. Engelschall]
2846 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
2847 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
2848 all available cipers including rc5, which was forgotten until now.
2849 In order to let the testing shell script know which algorithms
2850 are available, a new (up to now undocumented) command
2851 "openssl list-cipher-commands" is used.
2854 *) Bugfix: s_client occasionally would sleep in select() when
2855 it should have checked SSL_pending() first.
2858 *) New functions DSA_do_sign and DSA_do_verify to provide access to
2859 the raw DSA values prior to ASN.1 encoding.
2862 *) Tweaks to Configure
2863 [Niels Poppe <niels@netbox.org>]
2865 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
2869 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
2872 *) New config option to avoid instructions that are illegal on the 80386.
2873 The default code is faster, but requires at least a 486.
2876 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
2877 SSL2_SERVER_VERSION (not used at all) macros, which are now the
2878 same as SSL2_VERSION anyway.
2881 *) New "-showcerts" option for s_client.
2884 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
2885 application. Various cleanups and fixes.
2888 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
2889 modify error routines to work internally. Add error codes and PBE init
2890 to library startup routines.
2893 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
2894 packing functions to asn1 and evp. Changed function names and error
2895 codes along the way.
2898 *) PKCS12 integration: and so it begins... First of several patches to
2899 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
2900 objects to objects.h
2903 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
2904 and display support for Thawte strong extranet extension.
2907 *) Add LinuxPPC support.
2908 [Jeff Dubrule <igor@pobox.org>]
2910 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
2911 bn_div_words in alpha.s.
2912 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
2914 *) Make sure the RSA OAEP test is skipped under -DRSAref because
2915 OAEP isn't supported when OpenSSL is built with RSAref.
2916 [Ulf Moeller <ulf@fitug.de>]
2918 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
2919 so they no longer are missing under -DNOPROTO.
2920 [Soren S. Jorvang <soren@t.dk>]
2923 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
2925 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
2926 doesn't work when the session is reused. Coming soon!
2929 *) Fix a security hole, that allows sessions to be reused in the wrong
2930 context thus bypassing client cert protection! All software that uses
2931 client certs and session caches in multiple contexts NEEDS PATCHING to
2932 allow session reuse! A fuller solution is in the works.
2933 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
2935 *) Some more source tree cleanups (removed obsolete files
2936 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
2937 permission on "config" script to be executable) and a fix for the INSTALL
2939 [Ulf Moeller <ulf@fitug.de>]
2941 *) Remove some legacy and erroneous uses of malloc, free instead of
2943 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
2945 *) Make rsa_oaep_test return non-zero on error.
2946 [Ulf Moeller <ulf@fitug.de>]
2948 *) Add support for native Solaris shared libraries. Configure
2949 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
2950 if someone would make that last step automatic.
2951 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
2953 *) ctx_size was not built with the right compiler during "make links". Fixed.
2956 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
2957 except NULL ciphers". This means the default cipher list will no longer
2958 enable NULL ciphers. They need to be specifically enabled e.g. with
2959 the string "DEFAULT:eNULL".
2962 *) Fix to RSA private encryption routines: if p < q then it would
2963 occasionally produce an invalid result. This will only happen with
2964 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
2967 *) Be less restrictive and allow also `perl util/perlpath.pl
2968 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
2969 because this way one can also use an interpreter named `perl5' (which is
2970 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
2971 installed as `perl').
2972 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2974 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
2975 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2977 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
2978 advapi32.lib to Win32 build and change the pem test comparision
2979 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
2980 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
2981 and crypto/des/ede_cbcm_enc.c.
2984 *) DES quad checksum was broken on big-endian architectures. Fixed.
2987 *) Comment out two functions in bio.h that aren't implemented. Fix up the
2988 Win32 test batch file so it (might) work again. The Win32 test batch file
2989 is horrible: I feel ill....
2992 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
2993 in e_os.h. Audit of header files to check ANSI and non ANSI
2994 sections: 10 functions were absent from non ANSI section and not exported
2995 from Windows DLLs. Fixed up libeay.num for new functions.
2998 *) Make `openssl version' output lines consistent.
2999 [Ralf S. Engelschall]
3001 *) Fix Win32 symbol export lists for BIO functions: Added
3002 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
3003 to ms/libeay{16,32}.def.
3004 [Ralf S. Engelschall]
3006 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
3007 fine under Unix and passes some trivial tests I've now added. But the
3008 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
3009 added to make sure no one expects that this stuff really works in the
3010 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
3011 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
3013 [Ralf S. Engelschall]
3015 *) Fix the generation of two part addresses in perl.
3016 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
3018 *) Add config entry for Linux on MIPS.
3019 [John Tobey <jtobey@channel1.com>]
3021 *) Make links whenever Configure is run, unless we are on Windoze.
3024 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
3025 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
3029 *) Add a useful kludge to allow package maintainers to specify compiler and
3030 other platforms details on the command line without having to patch the
3031 Configure script everytime: One now can use ``perl Configure
3032 <id>:<details>'', i.e. platform ids are allowed to have details appended
3033 to them (seperated by colons). This is treated as there would be a static
3034 pre-configured entry in Configure's %table under key <id> with value
3035 <details> and ``perl Configure <id>'' is called. So, when you want to
3036 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
3037 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
3038 now, which overrides the FreeBSD-elf entry on-the-fly.
3039 [Ralf S. Engelschall]
3041 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
3044 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
3045 on the `perl Configure ...' command line. This way one can compile
3046 OpenSSL libraries with Position Independent Code (PIC) which is needed
3047 for linking it into DSOs.
3048 [Ralf S. Engelschall]
3050 *) Remarkably, export ciphers were totally broken and no-one had noticed!
3054 *) Cleaned up the LICENSE document: The official contact for any license
3055 questions now is the OpenSSL core team under openssl-core@openssl.org.
3056 And add a paragraph about the dual-license situation to make sure people
3057 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
3058 to the OpenSSL toolkit.
3059 [Ralf S. Engelschall]
3061 *) General source tree makefile cleanups: Made `making xxx in yyy...'
3062 display consistent in the source tree and replaced `/bin/rm' by `rm'.
3063 Additonally cleaned up the `make links' target: Remove unnecessary
3064 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
3065 to speed processing and no longer clutter the display with confusing
3066 stuff. Instead only the actually done links are displayed.
3067 [Ralf S. Engelschall]
3069 *) Permit null encryption ciphersuites, used for authentication only. It used
3070 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
3071 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
3075 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
3076 signed attributes when verifying signatures (this would break them),
3077 the detached data encoding was wrong and public keys obtained using
3078 X509_get_pubkey() weren't freed.
3081 *) Add text documentation for the BUFFER functions. Also added a work around
3082 to a Win95 console bug. This was triggered by the password read stuff: the
3083 last character typed gets carried over to the next fread(). If you were
3084 generating a new cert request using 'req' for example then the last
3085 character of the passphrase would be CR which would then enter the first
3089 *) Added the new `Includes OpenSSL Cryptography Software' button as
3090 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
3091 button and can be used by applications based on OpenSSL to show the
3092 relationship to the OpenSSL project.
3093 [Ralf S. Engelschall]
3095 *) Remove confusing variables in function signatures in files
3096 ssl/ssl_lib.c and ssl/ssl.h.
3097 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3099 *) Don't install bss_file.c under PREFIX/include/
3100 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3102 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
3103 functions that return function pointers and has support for NT specific
3104 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
3105 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
3106 unsigned to signed types: this was killing the Win32 compile.
3109 *) Add new certificate file to stack functions,
3110 SSL_add_dir_cert_subjects_to_stack() and
3111 SSL_add_file_cert_subjects_to_stack(). These largely supplant
3112 SSL_load_client_CA_file(), and can be used to add multiple certs easily
3113 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
3114 This means that Apache-SSL and similar packages don't have to mess around
3115 to add as many CAs as they want to the preferred list.
3118 *) Experiment with doxygen documentation. Currently only partially applied to
3120 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
3121 openssl.doxy as the configuration file.
3124 *) Get rid of remaining C++-style comments which strict C compilers hate.
3125 [Ralf S. Engelschall, pointed out by Carlos Amengual]
3127 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
3128 compiled in by default: it has problems with large keys.
3131 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
3132 DH private keys and/or callback functions which directly correspond to
3133 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
3134 is needed for applications which have to configure certificates on a
3135 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
3137 For the RSA certificate situation is makes no difference, but
3138 for the DSA certificate situation this fixes the "no shared cipher"
3139 problem where the OpenSSL cipher selection procedure failed because the
3140 temporary keys were not overtaken from the context and the API provided
3141 no way to reconfigure them.
3142 The new functions now let applications reconfigure the stuff and they
3143 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
3144 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
3145 non-public-API function ssl_cert_instantiate() is used as a helper
3146 function and also to reduce code redundancy inside ssl_rsa.c.
3147 [Ralf S. Engelschall]
3149 *) Move s_server -dcert and -dkey options out of the undocumented feature
3150 area because they are useful for the DSA situation and should be
3151 recognized by the users.
3152 [Ralf S. Engelschall]
3154 *) Fix the cipher decision scheme for export ciphers: the export bits are
3155 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
3156 SSL_EXP_MASK. So, the original variable has to be used instead of the
3157 already masked variable.
3158 [Richard Levitte <levitte@stacken.kth.se>]
3160 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
3161 [Richard Levitte <levitte@stacken.kth.se>]
3163 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
3164 from `int' to `unsigned int' because it's a length and initialized by
3165 EVP_DigestFinal() which expects an `unsigned int *'.
3166 [Richard Levitte <levitte@stacken.kth.se>]
3168 *) Don't hard-code path to Perl interpreter on shebang line of Configure
3169 script. Instead use the usual Shell->Perl transition trick.
3170 [Ralf S. Engelschall]
3172 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
3173 (in addition to RSA certificates) to match the behaviour of `openssl dsa
3174 -noout -modulus' as it's already the case for `openssl rsa -noout
3175 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
3176 currently the public key is printed (a decision which was already done by
3177 `openssl dsa -modulus' in the past) which serves a similar purpose.
3178 Additionally the NO_RSA no longer completely removes the whole -modulus
3179 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
3181 [Ralf S. Engelschall]
3183 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
3184 BIO. See the source (crypto/evp/bio_ok.c) for more info.
3185 [Arne Ansper <arne@ats.cyber.ee>]
3187 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
3188 to be added. Now both 'req' and 'ca' can use new objects defined in the
3192 *) Add cool BIO that does syslog (or event log on NT).
3193 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
3195 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
3196 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
3197 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
3198 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
3201 *) Add preliminary config info for new extension code.
3204 *) Make RSA_NO_PADDING really use no padding.
3205 [Ulf Moeller <ulf@fitug.de>]
3207 *) Generate errors when private/public key check is done.
3210 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
3211 for some CRL extensions and new objects added.
3214 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
3215 key usage extension and fuller support for authority key id.
3218 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
3219 padding method for RSA, which is recommended for new applications in PKCS
3220 #1 v2.0 (RFC 2437, October 1998).
3221 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
3222 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
3223 against Bleichbacher's attack on RSA.
3224 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
3227 *) Updates to the new SSL compression code
3228 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3230 *) Fix so that the version number in the master secret, when passed
3231 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
3232 (because the server will not accept higher), that the version number
3233 is 0x03,0x01, not 0x03,0x00
3234 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3236 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
3237 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
3238 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
3241 *) Support for RAW extensions where an arbitrary extension can be
3242 created by including its DER encoding. See apps/openssl.cnf for
3246 *) Make sure latest Perl versions don't interpret some generated C array
3247 code as Perl array code in the crypto/err/err_genc.pl script.
3248 [Lars Weber <3weber@informatik.uni-hamburg.de>]
3250 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
3251 not many people have the assembler. Various Win32 compilation fixes and
3252 update to the INSTALL.W32 file with (hopefully) more accurate Win32
3256 *) Modify configure script 'Configure' to automatically create crypto/date.h
3257 file under Win32 and also build pem.h from pem.org. New script
3258 util/mkfiles.pl to create the MINFO file on environments that can't do a
3259 'make files': perl util/mkfiles.pl >MINFO should work.
3262 *) Major rework of DES function declarations, in the pursuit of correctness
3263 and purity. As a result, many evil casts evaporated, and some weirdness,
3264 too. You may find this causes warnings in your code. Zapping your evil
3265 casts will probably fix them. Mostly.
3268 *) Fix for a typo in asn1.h. Bug fix to object creation script
3269 obj_dat.pl. It considered a zero in an object definition to mean
3270 "end of object": none of the objects in objects.h have any zeros
3271 so it wasn't spotted.
3272 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
3274 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
3275 Masking (CBCM). In the absence of test vectors, the best I have been able
3276 to do is check that the decrypt undoes the encrypt, so far. Send me test
3277 vectors if you have them.
3280 *) Correct calculation of key length for export ciphers (too much space was
3281 allocated for null ciphers). This has not been tested!
3284 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
3285 message is now correct (it understands "crypto" and "ssl" on its
3286 command line). There is also now an "update" option. This will update
3287 the util/ssleay.num and util/libeay.num files with any new functions.
3289 perl util/mkdef.pl crypto ssl update
3290 it will update them.
3293 *) Overhauled the Perl interface (perl/*):
3294 - ported BN stuff to OpenSSL's different BN library
3295 - made the perl/ source tree CVS-aware
3296 - renamed the package from SSLeay to OpenSSL (the files still contain
3297 their history because I've copied them in the repository)
3298 - removed obsolete files (the test scripts will be replaced
3299 by better Test::Harness variants in the future)
3300 [Ralf S. Engelschall]
3302 *) First cut for a very conservative source tree cleanup:
3303 1. merge various obsolete readme texts into doc/ssleay.txt
3304 where we collect the old documents and readme texts.
3305 2. remove the first part of files where I'm already sure that we no
3306 longer need them because of three reasons: either they are just temporary
3307 files which were left by Eric or they are preserved original files where
3308 I've verified that the diff is also available in the CVS via "cvs diff
3309 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
3310 the crypto/md/ stuff).
3311 [Ralf S. Engelschall]
3313 *) More extension code. Incomplete support for subject and issuer alt
3314 name, issuer and authority key id. Change the i2v function parameters
3315 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
3316 what that's for :-) Fix to ASN1 macro which messed up
3317 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
3320 *) Preliminary support for ENUMERATED type. This is largely copied from the
3324 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
3325 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3327 *) Make sure `make rehash' target really finds the `openssl' program.
3328 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3330 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
3331 like to hear about it if this slows down other processors.
3334 *) Add CygWin32 platform information to Configure script.
3335 [Alan Batie <batie@aahz.jf.intel.com>]
3337 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
3338 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
3340 *) New program nseq to manipulate netscape certificate sequences
3343 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
3347 *) Fixes to BN code. Previously the default was to define BN_RECURSION
3348 but the BN code had some problems that would cause failures when
3349 doing certificate verification and some other functions.
3350 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3352 *) Add ASN1 and PEM code to support netscape certificate sequences.
3355 *) Add ASN1 and PEM code to support netscape certificate sequences.
3358 *) Add several PKIX and private extended key usage OIDs.
3361 *) Modify the 'ca' program to handle the new extension code. Modify
3362 openssl.cnf for new extension format, add comments.
3365 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
3366 and add a sample to openssl.cnf so req -x509 now adds appropriate
3370 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
3371 error code, add initial support to X509_print() and x509 application.
3374 *) Takes a deep breath and start addding X509 V3 extension support code. Add
3375 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
3376 stuff is currently isolated and isn't even compiled yet.
3379 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
3380 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
3381 Removed the versions check from X509 routines when loading extensions:
3382 this allows certain broken certificates that don't set the version
3383 properly to be processed.
3386 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
3387 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
3388 can still be regenerated with "make depend".
3391 *) Spelling mistake in C version of CAST-128.
3392 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
3394 *) Changes to the error generation code. The perl script err-code.pl
3395 now reads in the old error codes and retains the old numbers, only
3396 adding new ones if necessary. It also only changes the .err files if new
3397 codes are added. The makefiles have been modified to only insert errors
3398 when needed (to avoid needlessly modifying header files). This is done
3399 by only inserting errors if the .err file is newer than the auto generated
3400 C file. To rebuild all the error codes from scratch (the old behaviour)
3401 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
3402 or delete all the .err files.
3405 *) CAST-128 was incorrectly implemented for short keys. The C version has
3406 been fixed, but is untested. The assembler versions are also fixed, but
3407 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
3408 to regenerate it if needed.
3409 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
3410 Hagino <itojun@kame.net>]
3412 *) File was opened incorrectly in randfile.c.
3413 [Ulf Möller <ulf@fitug.de>]
3415 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
3416 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
3417 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
3418 al: it's just almost always a UTCTime. Note this patch adds new error
3419 codes so do a "make errors" if there are problems.
3422 *) Correct Linux 1 recognition in config.
3423 [Ulf Möller <ulf@fitug.de>]
3425 *) Remove pointless MD5 hash when using DSA keys in ca.
3426 [Anonymous <nobody@replay.com>]
3428 *) Generate an error if given an empty string as a cert directory. Also
3429 generate an error if handed NULL (previously returned 0 to indicate an
3430 error, but didn't set one).
3431 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
3433 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
3436 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
3437 parameters. This was causing a warning which killed off the Win32 compile.
3440 *) Remove C++ style comments from crypto/bn/bn_local.h.
3441 [Neil Costigan <neil.costigan@celocom.com>]
3443 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
3444 based on a text string, looking up short and long names and finally
3445 "dot" format. The "dot" format stuff didn't work. Added new function
3446 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
3447 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
3448 OID is not part of the table.
3451 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
3452 X509_LOOKUP_by_alias().
3455 *) Sort openssl functions by name.
3458 *) Get the gendsa program working (hopefully) and add it to app list. Remove
3459 encryption from sample DSA keys (in case anyone is interested the password
3463 *) Make _all_ *_free functions accept a NULL pointer.
3464 [Frans Heymans <fheymans@isaserver.be>]
3466 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
3468 [Anonymous <nobody@replay.com>]
3470 *) s_server should send the CAfile as acceptable CAs, not its own cert.
3471 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3473 *) Don't blow it for numeric -newkey arguments to apps/req.
3474 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3476 *) Temp key "for export" tests were wrong in s3_srvr.c.
3477 [Anonymous <nobody@replay.com>]
3479 *) Add prototype for temp key callback functions
3480 SSL_CTX_set_tmp_{rsa,dh}_callback().
3483 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
3484 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
3487 *) X509_name_add_entry() freed the wrong thing after an error.
3488 [Arne Ansper <arne@ats.cyber.ee>]
3490 *) rsa_eay.c would attempt to free a NULL context.
3491 [Arne Ansper <arne@ats.cyber.ee>]
3493 *) BIO_s_socket() had a broken should_retry() on Windoze.
3494 [Arne Ansper <arne@ats.cyber.ee>]
3496 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
3497 [Arne Ansper <arne@ats.cyber.ee>]
3499 *) Make sure the already existing X509_STORE->depth variable is initialized
3500 in X509_STORE_new(), but document the fact that this variable is still
3501 unused in the certificate verification process.
3502 [Ralf S. Engelschall]
3504 *) Fix the various library and apps files to free up pkeys obtained from
3505 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
3508 *) Fix reference counting in X509_PUBKEY_get(). This makes
3509 demos/maurice/example2.c work, amongst others, probably.
3510 [Steve Henson and Ben Laurie]
3512 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
3513 `openssl' and second, the shortcut symlinks for the `openssl <command>'
3514 are no longer created. This way we have a single and consistent command
3515 line interface `openssl <command>', similar to `cvs <command>'.
3516 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
3518 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
3519 BIT STRING wrapper always have zero unused bits.
3522 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
3525 *) Make the top-level INSTALL documentation easier to understand.
3528 *) Makefiles updated to exit if an error occurs in a sub-directory
3529 make (including if user presses ^C) [Paul Sutton]
3531 *) Make Montgomery context stuff explicit in RSA data structure.
3534 *) Fix build order of pem and err to allow for generated pem.h.
3537 *) Fix renumbering bug in X509_NAME_delete_entry().
3540 *) Enhanced the err-ins.pl script so it makes the error library number
3541 global and can add a library name. This is needed for external ASN1 and
3542 other error libraries.
3545 *) Fixed sk_insert which never worked properly.
3548 *) Fix ASN1 macros so they can handle indefinite length construted
3549 EXPLICIT tags. Some non standard certificates use these: they can now
3553 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
3554 into a single doc/ssleay.txt bundle. This way the information is still
3555 preserved but no longer messes up this directory. Now it's new room for
3556 the new set of documenation files.
3557 [Ralf S. Engelschall]
3559 *) SETs were incorrectly DER encoded. This was a major pain, because they
3560 shared code with SEQUENCEs, which aren't coded the same. This means that
3561 almost everything to do with SETs or SEQUENCEs has either changed name or
3562 number of arguments.
3563 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
3565 *) Fix test data to work with the above.
3568 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
3569 was already fixed by Eric for 0.9.1 it seems.
3570 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
3572 *) Autodetect FreeBSD3.
3575 *) Fix various bugs in Configure. This affects the following platforms:
3579 unixware-2.0-pentium
3583 *) Eliminate generated files from CVS. Reorder tests to regenerate files
3584 before they are needed.

3665 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
3669 *) Add -strparse option to asn1pars program which parses nested
3671 [Dr Stephen Henson <shenson@bigfoot.com>]
3673 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
3676 *) DSA fix for "ca" program.

3685 *) Added -a (all) option to "ssleay version" command.
3688 *) Added PLATFORM define which is the id given to Configure.
3691 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
3694 *) Extended the ASN.1 parser routines.
3697 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.

3718 *) Added more RSA padding checks for SSL/TLS.
3721 *) Added BIO proxy/filter functionality.
3724 *) Added extra_certs to SSL_CTX which can be used
3725 send extra CA certificates to the client in the CA cert chain sending
3726 process. It can be configured with SSL_CTX_add_extra_chain_cert().
3729 *) Now Fortezza is denied in the authentication phase because
3730 this is key exchange mechanism is not supported by SSLeay at all.
3733 *) Additional PKCS1 checks.
3736 *) Support the string "TLSv1" for all TLS v1 ciphers.
3739 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
