5 Changes between 0.9.4 and 0.9.5 [xx XXX 2000]
7 *) In bntest.c don't call BN_rand with zero bits argument.
8 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
10 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
11 case was implemented. This caused BN_div_recp() to fail occasionally.
14 *) Add an optional second argument to the set_label() in the perl
15 assembly language builder. If this argument exists and is set
16 to 1 it signals that the assembler should use a symbol whose
17 scope is the entire file, not just the current function. This
18 is needed with MASM which uses the format label:: for this scope.
19 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
21 *) Change the ASN1 types so they are typedefs by default. Before
22 almost all types were #define'd to ASN1_STRING which was causing
23 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
27 *) Change names of new functions to the new get1/get0 naming
28 convention: After 'get1', the caller owns a reference count
29 and has to call ..._free; 'get0' returns a pointer to some
30 data structure without incrementing reference counters.
31 (Some of the existing 'get' functions increment a reference
33 Similarly, 'set1' and 'add1' functions increase reference
34 counters or duplicate objects.
37 *) Allow for the possibility of temp RSA key generation failure:
38 the code used to assume it always worked and crashed on failure.
41 *) Fix potential buffer overrun problem in BIO_printf().
42 [Ulf Möller, using public domain code by Patrick Powell; problem
43 pointed out by David Sacerdote <das33@cornell.edu>]
45 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
46 RAND_egd() and RAND_status(). In the command line application,
47 the EGD socket can be specified like a seed file using RANDFILE
51 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
52 Some CAs (e.g. Verisign) distribute certificates in this form.
55 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
56 list to exclude them. This means that no special compilation option
57 is needed to use anonymous DH: it just needs to be included in the
61 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
62 EVP_MD_type. The old functionality is available in a new macro called
63 EVP_MD_md(). Change code that uses it and update docs.
66 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
67 where the 'void *' argument is replaced by a function pointer argument.
68 Previously 'void *' was abused to point to functions, which works on
69 many platforms, but is not correct. As these functions are usually
70 called by macros defined in OpenSSL header files, most source code
71 should work without changes.
74 *) <openssl/opensslconf.h> (which is created by Configure) now contains
75 sections with information on -D... compiler switches used for
76 compiling the library so that applications can see them. To enable
77 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
78 must be defined. E.g.,
79 #define OPENSSL_ALGORITHM_DEFINES
80 #include <openssl/opensslconf.h>
81 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
82 [Richard Levitte, Ulf and Bodo Möller]
84 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
88 *) Change the 'other' type in certificate aux info to a STACK_OF
89 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
90 the required ASN1 format: arbitrary types determined by an OID.
93 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
94 argument to 'req'. This is not because the function is newer or
95 better than others it just uses the work 'NEW' in the certificate
96 request header lines. Some software needs this.
99 *) Reorganise password command line arguments: now passwords can be
100 obtained from various sources. Delete the PEM_cb function and make
101 it the default behaviour: i.e. if the callback is NULL and the
102 usrdata argument is not NULL interpret it as a null terminated pass
103 phrase. If usrdata and the callback are NULL then the pass phrase
104 is prompted for as usual.
107 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
108 the support is automatically enabled. The resulting binaries will
109 autodetect the card and use it if present.
110 [Ben Laurie and Compaq Inc.]
112 *) Work around for Netscape hang bug. This sends certificate request
113 and server done in one record. Since this is perfectly legal in the
114 SSL/TLS protocol it isn't a "bug" option and is on by default. See
115 the bugs/SSLv3 entry for more info.
118 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
121 *) Add -rand argument to smime and pkcs12 applications and read/write
125 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
128 *) Add command line password options to the remaining applications.
131 *) Bug fix for BN_div_recp() for numerators with an even number of
135 *) More tests in bntest.c, and changed test_bn output.
138 *) ./config recognizes MacOS X now.
141 *) Bug fix for BN_div() when the first words of num and divsor are
142 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
145 *) Add support for various broken PKCS#8 formats, and command line
146 options to produce them.
149 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
150 get temporary BIGNUMs from a BN_CTX.
153 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
157 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
158 include a #define from the old name to the new. The original intent
159 was that statically linked binaries could for example just call
160 SSLeay_add_all_ciphers() to just add ciphers to the table and not
161 link with digests. This never worked becayse SSLeay_add_all_digests()
162 and SSLeay_add_all_ciphers() were in the same source file so calling
163 one would link with the other. They are now in separate source files.
166 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
169 *) Use a less unusual form of the Miller-Rabin primality test (it used
170 a binary algorithm for exponentiation integrated into the Miller-Rabin
171 loop, our standard modexp algorithms are faster).
174 *) Support for the EBCDIC character set completed.
175 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
177 *) Source code cleanups: use const where appropriate, eliminate casts,
178 use void * instead of char * in lhash.
181 *) Bugfix: ssl3_send_server_key_exchange was not restartable
182 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
183 this the server could overwrite ephemeral keys that the client
187 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
188 using 50 iterations of the Rabin-Miller test.
190 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
191 iterations of the Rabin-Miller test as required by the appendix
192 to FIPS PUB 186[-1]) instead of DSA_is_prime.
193 As BN_is_prime_fasttest includes trial division, DSA parameter
194 generation becomes much faster.
196 This implies a change for the callback functions in DSA_is_prime
197 and DSA_generate_parameters: The callback function is called once
198 for each positive witness in the Rabin-Miller test, not just
199 occasionally in the inner loop; and the parameters to the
200 callback function now provide an iteration count for the outer
201 loop rather than for the current invocation of the inner loop.
202 DSA_generate_parameters additionally can call the callback
203 function with an 'iteration count' of -1, meaning that a
204 candidate has passed the trial division test (when q is generated
205 from an application-provided seed, trial division is skipped).
208 *) New function BN_is_prime_fasttest that optionally does trial
209 division before starting the Rabin-Miller test and has
210 an additional BN_CTX * argument (whereas BN_is_prime always
211 has to allocate at least one BN_CTX).
212 'callback(1, -1, cb_arg)' is called when a number has passed the
213 trial division stage.
216 *) Fix for bug in CRL encoding. The validity dates weren't being handled
220 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
223 *) New function BN_pseudo_rand().
226 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
227 bignum version of BN_from_montgomery() with the working code from
228 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
232 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
233 made it impossible to use the same SSL_SESSION data structure in
234 SSL2 clients in multiple threads.
237 *) The return value of RAND_load_file() no longer counts bytes obtained
238 by stat(). RAND_load_file(..., -1) is new and uses the complete file
239 to seed the PRNG (previously an explicit byte count was required).
240 [Ulf Möller, Bodo Möller]
242 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
243 used (char *) instead of (void *) and had casts all over the place.
246 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
249 *) Retain source code compatibility for BN_prime_checks macro:
250 BN_is_prime(..., BN_prime_checks, ...) now uses
251 BN_prime_checks_for_size to determine the appropriate number of
252 Rabin-Miller iterations.
255 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
256 DH_CHECK_P_NOT_SAFE_PRIME.
257 (Check if this is true? OpenPGP calls them "strong".)
260 *) Merge the functionality of "dh" and "gendh" programs into a new program
261 "dhparam". The old programs are retained for now but will handle DH keys
262 (instead of parameters) in future.
265 *) Make the ciphers, s_server and s_client programs check the return values
266 when a new cipher list is set.
269 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
270 ciphers. Before when the 56bit ciphers were enabled the sorting was
273 The syntax for the cipher sorting has been extended to support sorting by
274 cipher-strength (using the strength_bits hard coded in the tables).
275 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
277 Fix a bug in the cipher-command parser: when supplying a cipher command
278 string with an "undefined" symbol (neither command nor alphanumeric
279 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
282 Due to the strength-sorting extension, the code of the
283 ssl_create_cipher_list() function was completely rearranged. I hope that
284 the readability was also increased :-)
285 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
287 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
288 for the first serial number and places 2 in the serial number file. This
289 avoids problems when the root CA is created with serial number zero and
290 the first user certificate has the same issuer name and serial number
294 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
295 the new code. Add documentation for this stuff.
298 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
299 X509_*() to X509at_*() on the grounds that they don't handle X509
300 structures and behave in an analagous way to the X509v3 functions:
301 they shouldn't be called directly but wrapper functions should be used
304 So we also now have some wrapper functions that call the X509at functions
305 when passed certificate requests. (TO DO: similar things can be done with
306 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
307 things. Some of these need some d2i or i2d and print functionality
308 because they handle more complex structures.)
311 *) Add missing #ifndefs that caused missing symbols when building libssl
312 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
314 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
316 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
317 has a return value which indicates the quality of the random data
318 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
319 error queue. New function RAND_pseudo_bytes() generates output that is
320 guaranteed to be unique but not unpredictable. RAND_add is like
321 RAND_seed, but takes an extra argument for an entropy estimate
322 (RAND_seed always assumes full entropy).
325 *) Do more iterations of Rabin-Miller probable prime test (specifically,
326 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
327 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
328 in crypto/bn/bn_prime.c for the complete table). This guarantees a
329 false-positive rate of at most 2^-80 for random input.
332 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
335 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
336 in the 0.9.5 release), this returns the chain
337 from an X509_CTX structure with a dup of the stack and all
338 the X509 reference counts upped: so the stack will exist
339 after X509_CTX_cleanup() has been called. Modify pkcs12.c
342 Also make SSL_SESSION_print() print out the verify return
346 *) Add manpage for the pkcs12 command. Also change the default
347 behaviour so MAC iteration counts are used unless the new
348 -nomaciter option is used. This improves file security and
349 only older versions of MSIE (4.0 for example) need it.
352 *) Honor the no-xxx Configure options when creating .DEF files.
355 *) Add PKCS#10 attributes to field table: challengePassword,
356 unstructuredName and unstructuredAddress. These are taken from
357 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
358 international characters are used.
360 More changes to X509_ATTRIBUTE code: allow the setting of types
361 based on strings. Remove the 'loc' parameter when adding
362 attributes because these will be a SET OF encoding which is sorted
366 *) Initial changes to the 'req' utility to allow request generation
367 automation. This will allow an application to just generate a template
368 file containing all the field values and have req construct the
371 Initial support for X509_ATTRIBUTE handling. Stacks of these are
372 used all over the place including certificate requests and PKCS#7
373 structures. They are currently handled manually where necessary with
374 some primitive wrappers for PKCS#7. The new functions behave in a
375 manner analogous to the X509 extension functions: they allow
376 attributes to be looked up by NID and added.
378 Later something similar to the X509V3 code would be desirable to
379 automatically handle the encoding, decoding and printing of the
380 more complex types. The string types like challengePassword can
381 be handled by the string table functions.
383 Also modified the multi byte string table handling. Now there is
384 a 'global mask' which masks out certain types. The table itself
385 can use the flag STABLE_NO_MASK to ignore the mask setting: this
386 is useful when for example there is only one permissible type
387 (as in countryName) and using the mask might result in no valid
391 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
392 SSL_get_peer_finished to allow applications to obtain the latest
393 Finished messages sent to the peer or expected from the peer,
394 respectively. (SSL_get_peer_finished is usually the Finished message
395 actually received from the peer, otherwise the protocol will be aborted.)
397 As the Finished message are message digests of the complete handshake
398 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
399 be used for external authentication procedures when the authentication
400 provided by SSL/TLS is not desired or is not enough.
403 *) Enhanced support for Alpha Linux is added. Now ./config checks if
404 the host supports BWX extension and if Compaq C is present on the
405 $PATH. Just exploiting of the BWX extension results in 20-30%
406 performance kick for some algorithms, e.g. DES and RC4 to mention
407 a couple. Compaq C in turn generates ~20% faster code for MD5 and
411 *) Add support for MS "fast SGC". This is arguably a violation of the
412 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
413 weak crypto and after checking the certificate is SGC a second one
414 with strong crypto. MS SGC stops the first handshake after receiving
415 the server certificate message and sends a second client hello. Since
416 a server will typically do all the time consuming operations before
417 expecting any further messages from the client (server key exchange
418 is the most expensive) there is little difference between the two.
420 To get OpenSSL to support MS SGC we have to permit a second client
421 hello message after we have sent server done. In addition we have to
422 reset the MAC if we do get this second client hello.
425 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
426 if a DER encoded private key is RSA or DSA traditional format. Changed
427 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
428 format DER encoded private key. Newer code should use PKCS#8 format which
429 has the key type encoded in the ASN1 structure. Added DER private key
430 support to pkcs8 application.
433 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
434 ciphersuites has been selected (as required by the SSL 3/TLS 1
435 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
436 is set, we interpret this as a request to violate the specification
437 (the worst that can happen is a handshake failure, and 'correct'
438 behaviour would result in a handshake failure anyway).
441 *) In SSL_CTX_add_session, take into account that there might be multiple
442 SSL_SESSION structures with the same session ID (e.g. when two threads
443 concurrently obtain them from an external cache).
444 The internal cache can handle only one SSL_SESSION with a given ID,
445 so if there's a conflict, we now throw out the old one to achieve
449 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
450 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
451 some routines that use cipher OIDs: some ciphers do not have OIDs
452 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
456 *) Simplify the trust setting structure and code. Now we just have
457 two sequences of OIDs for trusted and rejected settings. These will
458 typically have values the same as the extended key usage extension
459 and any application specific purposes.
461 The trust checking code now has a default behaviour: it will just
462 check for an object with the same NID as the passed id. Functions can
463 be provided to override either the default behaviour or the behaviour
464 for a given id. SSL client, server and email already have functions
465 in place for compatibility: they check the NID and also return "trusted"
466 if the certificate is self signed.
469 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
470 traditional format into an EVP_PKEY structure.
473 *) Add a password callback function PEM_cb() which either prompts for
474 a password if usr_data is NULL or otherwise assumes it is a null
475 terminated password. Allow passwords to be passed on command line
476 environment or config files in a few more utilities.
479 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
480 keys. Add some short names for PKCS#8 PBE algorithms and allow them
481 to be specified on the command line for the pkcs8 and pkcs12 utilities.
482 Update documentation.
485 *) Support for ASN1 "NULL" type. This could be handled before by using
486 ASN1_TYPE but there wasn't any function that would try to read a NULL
487 and produce an error if it couldn't. For compatibility we also have
488 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
489 don't allocate anything because they don't need to.
492 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
494 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
496 *) Rebuild of the memory allocation routines used by OpenSSL code and
497 possibly others as well. The purpose is to make an interface that
498 provide hooks so anyone can build a separate set of allocation and
499 deallocation routines to be used by OpenSSL, for example memory
500 pool implementations, or something else, which was previously hard
501 since Malloc(), Realloc() and Free() were defined as macros having
502 the values malloc, realloc and free, respectively (except for Win32
503 compilations). The same is provided for memory debugging code.
504 OpenSSL already comes with functionality to find memory leaks, but
505 this gives people a chance to debug other memory problems.
507 With these changes, a new set of functions and macros have appeared:
509 CRYPTO_set_mem_debug_functions() [F]
510 CRYPTO_get_mem_debug_functions() [F]
511 CRYPTO_dbg_set_options() [F]
512 CRYPTO_dbg_get_options() [F]
513 CRYPTO_malloc_debug_init() [M]
515 The memory debug functions are NULL by default, unless the library
516 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
517 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
518 gives the standard debugging functions that come with OpenSSL) or
519 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
520 provided by the library user) must be used. When the standard
521 debugging functions are used, CRYPTO_dbg_set_options can be used to
522 request additional information:
523 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
524 the CRYPTO_MDEBUG_xxx macro when compiling the library.
526 Also, things like CRYPTO_set_mem_functions will always give the
527 expected result (the new set of functions is used for allocation
528 and deallocation) at all times, regardless of platform and compiler
531 To finish it up, some functions that were never use in any other
532 way than through macros have a new API and new semantic:
538 All macros of value have retained their old syntax.
539 [Richard Levitte and Bodo Moeller]
541 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
542 ordering of SMIMECapabilities wasn't in "strength order" and there
543 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
547 *) Some ASN1 types with illegal zero length encoding (INTEGER,
548 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
549 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
551 *) Merge in my S/MIME library for OpenSSL. This provides a simple
552 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
553 functionality to handle multipart/signed properly) and a utility
554 called 'smime' to call all this stuff. This is based on code I
555 originally wrote for Celo who have kindly allowed it to be
559 *) Add variants des_set_key_checked and des_set_key_unchecked of
560 des_set_key (aka des_key_sched). Global variable des_check_key
561 decides which of these is called by des_set_key; this way
562 des_check_key behaves as it always did, but applications and
563 the library itself, which was buggy for des_check_key == 1,
564 have a cleaner way to pick the version they need.
567 *) New function PKCS12_newpass() which changes the password of a
571 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
572 dynamic mix. In both cases the ids can be used as an index into the
573 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
574 functions so they accept a list of the field values and the
575 application doesn't need to directly manipulate the X509_TRUST
579 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
583 *) Modify the way the V3 extension code looks up extensions. This now
584 works in a similar way to the object code: we have some "standard"
585 extensions in a static table which is searched with OBJ_bsearch()
586 and the application can add dynamic ones if needed. The file
587 crypto/x509v3/ext_dat.h now has the info: this file needs to be
588 updated whenever a new extension is added to the core code and kept
589 in ext_nid order. There is a simple program 'tabtest.c' which checks
590 this. New extensions are not added too often so this file can readily
591 be maintained manually.
593 There are two big advantages in doing things this way. The extensions
594 can be looked up immediately and no longer need to be "added" using
595 X509V3_add_standard_extensions(): this function now does nothing.
596 [Side note: I get *lots* of email saying the extension code doesn't
597 work because people forget to call this function]
598 Also no dynamic allocation is done unless new extensions are added:
599 so if we don't add custom extensions there is no need to call
600 X509V3_EXT_cleanup().
603 *) Modify enc utility's salting as follows: make salting the default. Add a
604 magic header, so unsalted files fail gracefully instead of just decrypting
605 to garbage. This is because not salting is a big security hole, so people
606 should be discouraged from doing it.
609 *) Fixes and enhancements to the 'x509' utility. It allowed a message
610 digest to be passed on the command line but it only used this
611 parameter when signing a certificate. Modified so all relevant
612 operations are affected by the digest parameter including the
613 -fingerprint and -x509toreq options. Also -x509toreq choked if a
614 DSA key was used because it didn't fix the digest.
617 *) Initial certificate chain verify code. Currently tests the untrusted
618 certificates for consistency with the verify purpose (which is set
619 when the X509_STORE_CTX structure is set up) and checks the pathlength.
621 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
622 this is because it will reject chains with invalid extensions whereas
623 every previous version of OpenSSL and SSLeay made no checks at all.
625 Trust code: checks the root CA for the relevant trust settings. Trust
626 settings have an initial value consistent with the verify purpose: e.g.
627 if the verify purpose is for SSL client use it expects the CA to be
628 trusted for SSL client use. However the default value can be changed to
629 permit custom trust settings: one example of this would be to only trust
630 certificates from a specific "secure" set of CAs.
632 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
633 which should be used for version portability: especially since the
634 verify structure is likely to change more often now.
636 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
637 to set them. If not set then assume SSL clients will verify SSL servers
640 Two new options to the verify program: -untrusted allows a set of
641 untrusted certificates to be passed in and -purpose which sets the
642 intended purpose of the certificate. If a purpose is set then the
643 new chain verify code is used to check extension consistency.
646 *) Support for the authority information access extension.
649 *) Modify RSA and DSA PEM read routines to transparently handle
650 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
651 public keys in a format compatible with certificate
652 SubjectPublicKeyInfo structures. Unfortunately there were already
653 functions called *_PublicKey_* which used various odd formats so
654 these are retained for compatibility: however the DSA variants were
655 never in a public release so they have been deleted. Changed dsa/rsa
656 utilities to handle the new format: note no releases ever handled public
657 keys so we should be OK.
659 The primary motivation for this change is to avoid the same fiasco
660 that dogs private keys: there are several incompatible private key
661 formats some of which are standard and some OpenSSL specific and
662 require various evil hacks to allow partial transparent handling and
663 even then it doesn't work with DER formats. Given the option anything
664 other than PKCS#8 should be dumped: but the other formats have to
665 stay in the name of compatibility.
667 With public keys and the benefit of hindsight one standard format
668 is used which works with EVP_PKEY, RSA or DSA structures: though
669 it clearly returns an error if you try to read the wrong kind of key.
671 Added a -pubkey option to the 'x509' utility to output the public key.
672 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
673 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
674 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
675 that do the same as the EVP_PKEY_assign_*() except they up the
676 reference count of the added key (they don't "swallow" the
680 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
681 CRLs would fail if the file contained no certificates or no CRLs:
682 added a new function to read in both types and return the number
683 read: this means that if none are read it will be an error. The
684 DER versions of the certificate and CRL reader would always fail
685 because it isn't possible to mix certificates and CRLs in DER format
686 without choking one or the other routine. Changed this to just read
687 a certificate: this is the best we can do. Also modified the code
688 in apps/verify.c to take notice of return codes: it was previously
689 attempting to read in certificates from NULL pointers and ignoring
690 any errors: this is one reason why the cert and CRL reader seemed
691 to work. It doesn't check return codes from the default certificate
692 routines: these may well fail if the certificates aren't installed.
695 *) Code to support otherName option in GeneralName.
698 *) First update to verify code. Change the verify utility
699 so it warns if it is passed a self signed certificate:
700 for consistency with the normal behaviour. X509_verify
701 has been modified to it will now verify a self signed
702 certificate if *exactly* the same certificate appears
703 in the store: it was previously impossible to trust a
704 single self signed certificate. This means that:
705 openssl verify ss.pem
706 now gives a warning about a self signed certificate but
707 openssl verify -CAfile ss.pem ss.pem
711 *) For servers, store verify_result in SSL_SESSION data structure
712 (and add it to external session representation).
713 This is needed when client certificate verifications fails,
714 but an application-provided verification callback (set by
715 SSL_CTX_set_cert_verify_callback) allows accepting the session
716 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
717 but returns 1): When the session is reused, we have to set
718 ssl->verify_result to the appropriate error code to avoid
720 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
722 *) Fix a bug in the new PKCS#7 code: it didn't consider the
723 case in PKCS7_dataInit() where the signed PKCS7 structure
724 didn't contain any existing data because it was being created.
725 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
727 *) Add a salt to the key derivation routines in enc.c. This
728 forms the first 8 bytes of the encrypted file. Also add a
729 -S option to allow a salt to be input on the command line.
732 *) New function X509_cmp(). Oddly enough there wasn't a function
733 to compare two certificates. We do this by working out the SHA1
734 hash and comparing that. X509_cmp() will be needed by the trust
738 *) SSL_get1_session() is like SSL_get_session(), but increments
739 the reference count in the SSL_SESSION returned.
740 [Geoff Thorpe <geoff@eu.c2.net>]
742 *) Fix for 'req': it was adding a null to request attributes.
743 Also change the X509_LOOKUP and X509_INFO code to handle
744 certificate auxiliary information.
747 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
751 *) Add the possibility to add extra information to the memory leak
752 detecting output, to form tracebacks, showing from where each
753 allocation was originated: CRYPTO_push_info("constant string") adds
754 the string plus current file name and line number to a per-thread
755 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
756 is like calling CYRPTO_pop_info() until the stack is empty.
757 Also updated memory leak detection code to be multi-thread-safe.
760 *) Add options -text and -noout to pkcs7 utility and delete the
761 encryption options which never did anything. Update docs.
764 *) Add options to some of the utilities to allow the pass phrase
765 to be included on either the command line (not recommended on
766 OSes like Unix) or read from the environment. Update the
767 manpages and fix a few bugs.
770 *) Add a few manpages for some of the openssl commands.
773 *) Fix the -revoke option in ca. It was freeing up memory twice,
774 leaking and not finding already revoked certificates.
777 *) Extensive changes to support certificate auxiliary information.
778 This involves the use of X509_CERT_AUX structure and X509_AUX
779 functions. An X509_AUX function such as PEM_read_X509_AUX()
780 can still read in a certificate file in the usual way but it
781 will also read in any additional "auxiliary information". By
782 doing things this way a fair degree of compatibility can be
783 retained: existing certificates can have this information added
784 using the new 'x509' options.
786 Current auxiliary information includes an "alias" and some trust
787 settings. The trust settings will ultimately be used in enhanced
788 certificate chain verification routines: currently a certificate
789 can only be trusted if it is self signed and then it is trusted
793 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
794 The problem was that one of the replacement routines had not been working
795 since SSLeay releases. For now the offending routine has been replaced
796 with non-optimised assembler. Even so, this now gives around 95%
797 performance improvement for 1024 bit RSA signs.
800 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
801 handling. Most clients have the effective key size in bits equal to
802 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
803 A few however don't do this and instead use the size of the decrypted key
804 to determine the RC2 key length and the AlgorithmIdentifier to determine
805 the effective key length. In this case the effective key length can still
806 be 40 bits but the key length can be 168 bits for example. This is fixed
807 by manually forcing an RC2 key into the EVP_PKEY structure because the
808 EVP code can't currently handle unusual RC2 key sizes: it always assumes
809 the key length and effective key length are equal.
812 *) Add a bunch of functions that should simplify the creation of
813 X509_NAME structures. Now you should be able to do:
814 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
815 and have it automatically work out the correct field type and fill in
816 the structures. The more adventurous can try:
817 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
818 and it will (hopefully) work out the correct multibyte encoding.
821 *) Change the 'req' utility to use the new field handling and multibyte
822 copy routines. Before the DN field creation was handled in an ad hoc
823 way in req, ca, and x509 which was rather broken and didn't support
824 BMPStrings or UTF8Strings. Since some software doesn't implement
825 BMPStrings or UTF8Strings yet, they can be enabled using the config file
826 using the dirstring_type option. See the new comment in the default
827 openssl.cnf for more info.
830 *) Make crypto/rand/md_rand.c more robust:
831 - Assure unique random numbers after fork().
832 - Make sure that concurrent threads access the global counter and
833 md serializably so that we never lose entropy in them
834 or use exactly the same state in multiple threads.
835 Access to the large state is not always serializable because
836 the additional locking could be a performance killer, and
837 md should be large enough anyway.
840 *) New file apps/app_rand.c with commonly needed functionality
841 for handling the random seed file.
843 Use the random seed file in some applications that previously did not:
845 dsaparam -genkey (which also ignored its '-rand' option),
849 Except on systems with /dev/urandom, it is crucial to have a random
850 seed file at least for key creation, DSA signing, and for DH exchanges;
851 for RSA signatures we could do without one.
853 gendh and gendsa (unlike genrsa) used to read only the first byte
854 of each file listed in the '-rand' option. The function as previously
855 found in genrsa is now in app_rand.c and is used by all programs
856 that support '-rand'.
859 *) In RAND_write_file, use mode 0600 for creating files;
860 don't just chmod when it may be too late.
863 *) Report an error from X509_STORE_load_locations
864 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
867 *) New function ASN1_mbstring_copy() this copies a string in either
868 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
869 into an ASN1_STRING type. A mask of permissible types is passed
870 and it chooses the "minimal" type to use or an error if not type
874 *) Add function equivalents to the various macros in asn1.h. The old
875 macros are retained with an M_ prefix. Code inside the library can
876 use the M_ macros. External code (including the openssl utility)
877 should *NOT* in order to be "shared library friendly".
880 *) Add various functions that can check a certificate's extensions
881 to see if it usable for various purposes such as SSL client,
882 server or S/MIME and CAs of these types. This is currently
883 VERY EXPERIMENTAL but will ultimately be used for certificate chain
884 verification. Also added a -purpose flag to x509 utility to
885 print out all the purposes.
888 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
892 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
893 for, obtain and decode and extension and obtain its critical flag.
894 This allows all the necessary extension code to be handled in a
895 single function call.
898 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
899 platforms. See crypto/rc4/rc4_enc.c for further details.
902 *) New -noout option to asn1parse. This causes no output to be produced
903 its main use is when combined with -strparse and -out to extract data
904 from a file (which may not be in ASN.1 format).
907 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
908 when producing the local key id.
909 [Richard Levitte <levitte@stacken.kth.se>]
911 *) New option -dhparam in s_server. This allows a DH parameter file to be
912 stated explicitly. If it is not stated then it tries the first server
913 certificate file. The previous behaviour hard coded the filename
917 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
918 a public key to be input or output. For example:
919 openssl rsa -in key.pem -pubout -out pubkey.pem
920 Also added necessary DSA public key functions to handle this.
923 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
924 in the message. This was handled by allowing
925 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
926 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
928 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
929 to the end of the strings whereas this didn't. This would cause problems
930 if strings read with d2i_ASN1_bytes() were later modified.
931 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
933 *) Fix for base64 decode bug. When a base64 bio reads only one line of
934 data and it contains EOF it will end up returning an error. This is
935 caused by input 46 bytes long. The cause is due to the way base64
936 BIOs find the start of base64 encoded data. They do this by trying a
937 trial decode on each line until they find one that works. When they
938 do a flag is set and it starts again knowing it can pass all the
939 data directly through the decoder. Unfortunately it doesn't reset
940 the context it uses. This means that if EOF is reached an attempt
941 is made to pass two EOFs through the context and this causes the
942 resulting error. This can also cause other problems as well. As is
943 usual with these problems it takes *ages* to find and the fix is
944 trivial: move one line.
945 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
947 *) Ugly workaround to get s_client and s_server working under Windows. The
948 old code wouldn't work because it needed to select() on sockets and the
949 tty (for keypresses and to see if data could be written). Win32 only
950 supports select() on sockets so we select() with a 1s timeout on the
951 sockets and then see if any characters are waiting to be read, if none
952 are present then we retry, we also assume we can always write data to
953 the tty. This isn't nice because the code then blocks until we've
954 received a complete line of data and it is effectively polling the
955 keyboard at 1s intervals: however it's quite a bit better than not
956 working at all :-) A dedicated Windows application might handle this
957 with an event loop for example.
960 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
961 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
962 will be called when RSA_sign() and RSA_verify() are used. This is useful
963 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
964 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
965 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
966 This necessitated the support of an extra signature type NID_md5_sha1
967 for SSL signatures and modifications to the SSL library to use it instead
968 of calling RSA_public_decrypt() and RSA_private_encrypt().
971 *) Add new -verify -CAfile and -CApath options to the crl program, these
972 will lookup a CRL issuers certificate and verify the signature in a
973 similar way to the verify program. Tidy up the crl program so it
974 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
975 less strict. It will now permit CRL extensions even if it is not
976 a V2 CRL: this will allow it to tolerate some broken CRLs.
979 *) Initialize all non-automatic variables each time one of the openssl
980 sub-programs is started (this is necessary as they may be started
981 multiple times from the "OpenSSL>" prompt).
982 [Lennart Bang, Bodo Moeller]
984 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
985 removing all other RSA functionality (this is what NO_RSA does). This
986 is so (for example) those in the US can disable those operations covered
987 by the RSA patent while allowing storage and parsing of RSA keys and RSA
991 *) Non-copying interface to BIO pairs.
992 (still largely untested)
995 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
996 ASCII string. This was handled independently in various places before.
999 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
1000 UTF8 strings a character at a time.
1003 *) Use client_version from client hello to select the protocol
1004 (s23_srvr.c) and for RSA client key exchange verification
1005 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
1008 *) Add various utility functions to handle SPKACs, these were previously
1009 handled by poking round in the structure internals. Added new function
1010 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
1011 print, verify and generate SPKACs. Based on an original idea from
1012 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
1015 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
1018 *) Allow the config file extension section to be overwritten on the
1019 command line. Based on an original idea from Massimiliano Pala
1020 <madwolf@comune.modena.it>. The new option is called -extensions
1021 and can be applied to ca, req and x509. Also -reqexts to override
1022 the request extensions in req and -crlexts to override the crl extensions
1026 *) Add new feature to the SPKAC handling in ca. Now you can include
1027 the same field multiple times by preceding it by "XXXX." for example:
1030 this is the same syntax as used in the req config file.
1033 *) Allow certificate extensions to be added to certificate requests. These
1034 are specified in a 'req_extensions' option of the req section of the
1035 config file. They can be printed out with the -text option to req but
1036 are otherwise ignored at present.
1039 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
1040 data read consists of only the final block it would not decrypted because
1041 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
1042 A misplaced 'break' also meant the decrypted final block might not be
1043 copied until the next read.
1046 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
1047 a few extra parameters to the DH structure: these will be useful if
1048 for example we want the value of 'q' or implement X9.42 DH.
1051 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
1052 provides hooks that allow the default DSA functions or functions on a
1053 "per key" basis to be replaced. This allows hardware acceleration and
1054 hardware key storage to be handled without major modification to the
1055 library. Also added low level modexp hooks and CRYPTO_EX structure and
1056 associated functions.
1059 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
1060 as "read only": it can't be written to and the buffer it points to will
1061 not be freed. Reading from a read only BIO is much more efficient than
1062 a normal memory BIO. This was added because there are several times when
1063 an area of memory needs to be read from a BIO. The previous method was
1064 to create a memory BIO and write the data to it, this results in two
1065 copies of the data and an O(n^2) reading algorithm. There is a new
1066 function BIO_new_mem_buf() which creates a read only memory BIO from
1067 an area of memory. Also modified the PKCS#7 routines to use read only
1071 *) Bugfix: ssl23_get_client_hello did not work properly when called in
1072 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
1073 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
1074 but a retry condition occured while trying to read the rest.
1077 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
1078 NID_pkcs7_encrypted by default: this was wrong since this should almost
1079 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
1080 the encrypted data type: this is a more sensible place to put it and it
1081 allows the PKCS#12 code to be tidied up that duplicated this
1085 *) Changed obj_dat.pl script so it takes its input and output files on
1086 the command line. This should avoid shell escape redirection problems
1090 *) Initial support for certificate extension requests, these are included
1091 in things like Xenroll certificate requests. Included functions to allow
1092 extensions to be obtained and added.
1095 *) -crlf option to s_client and s_server for sending newlines as
1096 CRLF (as required by many protocols).
1099 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
1101 *) Install libRSAglue.a when OpenSSL is built with RSAref.
1102 [Ralf S. Engelschall]
1104 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
1105 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
1107 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
1111 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
1112 DH parameters/keys (q is lost during that conversion, but the resulting
1113 DH parameters contain its length).
1115 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
1116 much faster than DH_generate_parameters (which creates parameters
1117 where p = 2*q + 1), and also the smaller q makes DH computations
1118 much more efficient (160-bit exponentiation instead of 1024-bit
1119 exponentiation); so this provides a convenient way to support DHE
1120 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
1121 utter importance to use
1122 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1124 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1125 when such DH parameters are used, because otherwise small subgroup
1126 attacks may become possible!
1129 *) Avoid memory leak in i2d_DHparams.
1132 *) Allow the -k option to be used more than once in the enc program:
1133 this allows the same encrypted message to be read by multiple recipients.
1136 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
1137 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
1138 it will always use the numerical form of the OID, even if it has a short
1142 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
1143 method only got called if p,q,dmp1,dmq1,iqmp components were present,
1144 otherwise bn_mod_exp was called. In the case of hardware keys for example
1145 no private key components need be present and it might store extra data
1146 in the RSA structure, which cannot be accessed from bn_mod_exp.
1147 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
1148 private key operations.
1151 *) Added support for SPARC Linux.
1154 *) pem_password_cb function type incompatibly changed from
1155 typedef int pem_password_cb(char *buf, int size, int rwflag);
1157 ....(char *buf, int size, int rwflag, void *userdata);
1158 so that applications can pass data to their callbacks:
1159 The PEM[_ASN1]_{read,write}... functions and macros now take an
1160 additional void * argument, which is just handed through whenever
1161 the password callback is called.
1162 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
1164 New function SSL_CTX_set_default_passwd_cb_userdata.
1166 Compatibility note: As many C implementations push function arguments
1167 onto the stack in reverse order, the new library version is likely to
1168 interoperate with programs that have been compiled with the old
1169 pem_password_cb definition (PEM_whatever takes some data that
1170 happens to be on the stack as its last argument, and the callback
1171 just ignores this garbage); but there is no guarantee whatsoever that
1174 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
1175 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
1176 problems not only on Windows, but also on some Unix platforms.
1177 To avoid problematic command lines, these definitions are now in an
1178 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
1179 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
1182 *) MIPS III/IV assembler module is reimplemented.
1185 *) More DES library cleanups: remove references to srand/rand and
1186 delete an unused file.
1189 *) Add support for the the free Netwide assembler (NASM) under Win32,
1190 since not many people have MASM (ml) and it can be hard to obtain.
1191 This is currently experimental but it seems to work OK and pass all
1192 the tests. Check out INSTALL.W32 for info.
1195 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
1196 without temporary keys kept an extra copy of the server key,
1197 and connections with temporary keys did not free everything in case
1201 *) New function RSA_check_key and new openssl rsa option -check
1202 for verifying the consistency of RSA keys.
1203 [Ulf Moeller, Bodo Moeller]
1205 *) Various changes to make Win32 compile work:
1206 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
1207 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
1208 comparison" warnings.
1209 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
1212 *) Add a debugging option to PKCS#5 v2 key generation function: when
1213 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
1214 derived keys are printed to stderr.
1217 *) Copy the flags in ASN1_STRING_dup().
1218 [Roman E. Pavlov <pre@mo.msk.ru>]
1220 *) The x509 application mishandled signing requests containing DSA
1221 keys when the signing key was also DSA and the parameters didn't match.
1223 It was supposed to omit the parameters when they matched the signing key:
1224 the verifying software was then supposed to automatically use the CA's
1225 parameters if they were absent from the end user certificate.
1227 Omitting parameters is no longer recommended. The test was also
1228 the wrong way round! This was probably due to unusual behaviour in
1229 EVP_cmp_parameters() which returns 1 if the parameters match.
1230 This meant that parameters were omitted when they *didn't* match and
1231 the certificate was useless. Certificates signed with 'ca' didn't have
1233 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
1235 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
1236 The interface is as follows:
1237 Applications can use
1238 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
1239 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
1240 "off" is now the default.
1241 The library internally uses
1242 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
1243 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
1244 to disable memory-checking temporarily.
1246 Some inconsistent states that previously were possible (and were
1247 even the default) are now avoided.
1249 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
1250 with each memory chunk allocated; this is occasionally more helpful
1251 than just having a counter.
1253 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
1255 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
1259 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
1260 which largely parallels "options", but is for changing API behaviour,
1261 whereas "options" are about protocol behaviour.
1262 Initial "mode" flags are:
1264 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
1265 a single record has been written.
1266 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
1267 retries use the same buffer location.
1268 (But all of the contents must be
1272 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
1275 *) Fix problems with no-hmac etc.
1276 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
1278 *) New functions RSA_get_default_method(), RSA_set_method() and
1279 RSA_get_method(). These allows replacement of RSA_METHODs without having
1280 to mess around with the internals of an RSA structure.
1283 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
1284 Also really enable memory leak checks in openssl.c and in some
1286 [Chad C. Mulligan, Bodo Moeller]
1288 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
1289 up the length of negative integers. This has now been simplified to just
1290 store the length when it is first determined and use it later, rather
1291 than trying to keep track of where data is copied and updating it to
1293 [Steve Henson, reported by Brien Wheeler
1294 <bwheeler@authentica-security.com>]
1296 *) Add a new function PKCS7_signatureVerify. This allows the verification
1297 of a PKCS#7 signature but with the signing certificate passed to the
1298 function itself. This contrasts with PKCS7_dataVerify which assumes the
1299 certificate is present in the PKCS#7 structure. This isn't always the
1300 case: certificates can be omitted from a PKCS#7 structure and be
1301 distributed by "out of band" means (such as a certificate database).
1304 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
1305 function prototypes in pem.h, also change util/mkdef.pl to add the
1306 necessary function names.
1309 *) mk1mf.pl (used by Windows builds) did not properly read the
1310 options set by Configure in the top level Makefile, and Configure
1311 was not even able to write more than one option correctly.
1312 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
1315 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
1316 file to be loaded from a BIO or FILE pointer. The BIO version will
1317 for example allow memory BIOs to contain config info.
1320 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
1321 Whoever hopes to achieve shared-library compatibility across versions
1322 must use this, not the compile-time macro.
1323 (Exercise 0.9.4: Which is the minimum library version required by
1325 Note: All this applies only to multi-threaded programs, others don't
1329 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
1330 through a BIO pair triggered the default case, i.e.
1331 SSLerr(...,SSL_R_UNKNOWN_STATE).
1334 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
1335 can use the SSL library even if none of the specific BIOs is
1339 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
1340 for the encoded length.
1341 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
1343 *) Add initial documentation of the X509V3 functions.
1346 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
1347 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
1348 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
1349 secure PKCS#8 private key format with a high iteration count.
1352 *) Fix determination of Perl interpreter: A perl or perl5
1353 _directory_ in $PATH was also accepted as the interpreter.
1354 [Ralf S. Engelschall]
1356 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
1357 wrong with it but it was very old and did things like calling
1358 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
1362 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
1363 to use the new extension code.
1366 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
1367 with macros. This should make it easier to change their form, add extra
1368 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
1372 *) Add to configuration table a new entry that can specify an alternative
1373 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
1374 according to Mark Crispin <MRC@Panda.COM>.
1378 *) DES CBC did not update the IV. Weird.
1381 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
1382 Changing the behaviour of the former might break existing programs --
1383 where IV updating is needed, des_ncbc_encrypt can be used.
1386 *) When bntest is run from "make test" it drives bc to check its
1387 calculations, as well as internally checking them. If an internal check
1388 fails, it needs to cause bc to give a non-zero result or make test carries
1389 on without noticing the failure. Fixed.
1392 *) DES library cleanups.
1395 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
1396 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
1397 ciphers. NOTE: although the key derivation function has been verified
1398 against some published test vectors it has not been extensively tested
1399 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
1403 *) Instead of "mkdir -p", which is not fully portable, use new
1404 Perl script "util/mkdir-p.pl".
1407 *) Rewrite the way password based encryption (PBE) is handled. It used to
1408 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
1409 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
1410 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
1411 the 'parameter' field of the AlgorithmIdentifier is passed to the
1412 underlying key generation function so it must do its own ASN1 parsing.
1413 This has also changed the EVP_PBE_CipherInit() function which now has a
1414 'parameter' argument instead of literal salt and iteration count values
1415 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
1418 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
1419 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
1420 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
1421 KEY" because this clashed with PKCS#8 unencrypted string. Since this
1422 value was just used as a "magic string" and not used directly its
1423 value doesn't matter.
1426 *) Introduce some semblance of const correctness to BN. Shame C doesn't
1430 *) "linux-sparc64" configuration (ultrapenguin).
1431 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
1432 "linux-sparc" configuration.
1433 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
1435 *) config now generates no-xxx options for missing ciphers.
1438 *) Support the EBCDIC character set (work in progress).
1439 File ebcdic.c not yet included because it has a different license.
1440 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1442 *) Support BS2000/OSD-POSIX.
1443 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1445 *) Make callbacks for key generation use void * instead of char *.
1448 *) Make S/MIME samples compile (not yet tested).
1451 *) Additional typesafe stacks.
1454 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
1458 Changes between 0.9.3 and 0.9.3a [29 May 1999]
1460 *) New configuration variant "sco5-gcc".
1462 *) Updated some demos.
1463 [Sean O Riordain, Wade Scholine]
1465 *) Add missing BIO_free at exit of pkcs12 application.
1468 *) Fix memory leak in conf.c.
1471 *) Updates for Win32 to assembler version of MD5.
1474 *) Set #! path to perl in apps/der_chop to where we found it
1475 instead of using a fixed path.
1478 *) SHA library changes for irix64-mips4-cc.
1481 *) Improvements for VMS support.
1485 Changes between 0.9.2b and 0.9.3 [24 May 1999]
1487 *) Bignum library bug fix. IRIX 6 passes "make test" now!
1488 This also avoids the problems with SC4.2 and unpatched SC5.
1489 [Andy Polyakov <appro@fy.chalmers.se>]
1491 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
1492 These are required because of the typesafe stack would otherwise break
1493 existing code. If old code used a structure member which used to be STACK
1494 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
1495 sk_num or sk_value it would produce an error because the num, data members
1496 are not present in STACK_OF. Now it just produces a warning. sk_set
1497 replaces the old method of assigning a value to sk_value
1498 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
1499 that does this will no longer work (and should use sk_set instead) but
1500 this could be regarded as a "questionable" behaviour anyway.
1503 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
1504 correctly handle encrypted S/MIME data.
1507 *) Change type of various DES function arguments from des_cblock
1508 (which means, in function argument declarations, pointer to char)
1509 to des_cblock * (meaning pointer to array with 8 char elements),
1510 which allows the compiler to do more typechecking; it was like
1511 that back in SSLeay, but with lots of ugly casts.
1513 Introduce new type const_des_cblock.
1516 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
1517 problems: find RecipientInfo structure that matches recipient certificate
1518 and initialise the ASN1 structures properly based on passed cipher.
1521 *) Belatedly make the BN tests actually check the results.
1524 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
1525 to and from BNs: it was completely broken. New compilation option
1526 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
1527 key elements as negative integers.
1530 *) Reorganize and speed up MD5.
1531 [Andy Polyakov <appro@fy.chalmers.se>]
1534 [Richard Levitte <richard@levitte.org>]
1536 *) New option -out to asn1parse to allow the parsed structure to be
1537 output to a file. This is most useful when combined with the -strparse
1538 option to examine the output of things like OCTET STRINGS.
1541 *) Make SSL library a little more fool-proof by not requiring any longer
1542 that SSL_set_{accept,connect}_state be called before
1543 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
1544 in many applications because usually everything *appeared* to work as
1545 intended anyway -- now it really works as intended).
1548 *) Move openssl.cnf out of lib/.
1551 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
1552 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
1553 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
1554 [Ralf S. Engelschall]
1556 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
1557 handle PKCS#7 enveloped data properly.
1558 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
1560 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
1561 copying pointers. The cert_st handling is changed by this in
1562 various ways (and thus what used to be known as ctx->default_cert
1563 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
1564 any longer when s->cert does not give us what we need).
1565 ssl_cert_instantiate becomes obsolete by this change.
1566 As soon as we've got the new code right (possibly it already is?),
1567 we have solved a couple of bugs of the earlier code where s->cert
1568 was used as if it could not have been shared with other SSL structures.
1570 Note that using the SSL API in certain dirty ways now will result
1571 in different behaviour than observed with earlier library versions:
1572 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
1573 does not influence s as it used to.
1575 In order to clean up things more thoroughly, inside SSL_SESSION
1576 we don't use CERT any longer, but a new structure SESS_CERT
1577 that holds per-session data (if available); currently, this is
1578 the peer's certificate chain and, for clients, the server's certificate
1579 and temporary key. CERT holds only those values that can have
1580 meaningful defaults in an SSL_CTX.
1583 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
1584 from the internal representation. Various PKCS#7 fixes: remove some
1585 evil casts and set the enc_dig_alg field properly based on the signing
1589 *) Allow PKCS#12 password to be set from the command line or the
1590 environment. Let 'ca' get its config file name from the environment
1591 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
1595 *) Allow certificate policies extension to use an IA5STRING for the
1596 organization field. This is contrary to the PKIX definition but
1597 VeriSign uses it and IE5 only recognises this form. Document 'x509'
1601 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
1602 without disallowing inline assembler and the like for non-pedantic builds.
1605 *) Support Borland C++ builder.
1606 [Janez Jere <jj@void.si>, modified by Ulf Möller]
1611 *) SHA-1 cleanups and performance enhancements.
1612 [Andy Polyakov <appro@fy.chalmers.se>]
1614 *) Sparc v8plus assembler for the bignum library.
1615 [Andy Polyakov <appro@fy.chalmers.se>]
1617 *) Accept any -xxx and +xxx compiler options in Configure.
1620 *) Update HPUX configuration.
1623 *) Add missing sk_<type>_unshift() function to safestack.h
1624 [Ralf S. Engelschall]
1626 *) New function SSL_CTX_use_certificate_chain_file that sets the
1627 "extra_cert"s in addition to the certificate. (This makes sense
1628 only for "PEM" format files, as chains as a whole are not
1632 *) Support verify_depth from the SSL API.
1633 x509_vfy.c had what can be considered an off-by-one-error:
1634 Its depth (which was not part of the external interface)
1635 was actually counting the number of certificates in a chain;
1636 now it really counts the depth.
1639 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
1640 instead of X509err, which often resulted in confusing error
1641 messages since the error codes are not globally unique
1642 (e.g. an alleged error in ssl3_accept when a certificate
1643 didn't match the private key).
1645 *) New function SSL_CTX_set_session_id_context that allows to set a default
1646 value (so that you don't need SSL_set_session_id_context for each
1647 connection using the SSL_CTX).
1650 *) OAEP decoding bug fix.
1653 *) Support INSTALL_PREFIX for package builders, as proposed by
1657 *) New Configure options "threads" and "no-threads". For systems
1658 where the proper compiler options are known (currently Solaris
1659 and Linux), "threads" is the default.
1662 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
1665 *) Install various scripts to $(OPENSSLDIR)/misc, not to
1666 $(INSTALLTOP)/bin -- they shouldn't clutter directories
1667 such as /usr/local/bin.
1670 *) "make linux-shared" to build shared libraries.
1671 [Niels Poppe <niels@netbox.org>]
1673 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
1676 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
1677 extension adding in x509 utility.
1680 *) Remove NOPROTO sections and error code comments.
1683 *) Partial rewrite of the DEF file generator to now parse the ANSI
1687 *) New Configure options --prefix=DIR and --openssldir=DIR.
1690 *) Complete rewrite of the error code script(s). It is all now handled
1691 by one script at the top level which handles error code gathering,
1692 header rewriting and C source file generation. It should be much better
1693 than the old method: it now uses a modified version of Ulf's parser to
1694 read the ANSI prototypes in all header files (thus the old K&R definitions
1695 aren't needed for error creation any more) and do a better job of
1696 translating function codes into names. The old 'ASN1 error code imbedded
1697 in a comment' is no longer necessary and it doesn't use .err files which
1698 have now been deleted. Also the error code call doesn't have to appear all
1699 on one line (which resulted in some large lines...).
1702 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
1705 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
1706 0 (which usually indicates a closed connection), but continue reading.
1709 *) Fix some race conditions.
1712 *) Add support for CRL distribution points extension. Add Certificate
1713 Policies and CRL distribution points documentation.
1716 *) Move the autogenerated header file parts to crypto/opensslconf.h.
1719 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
1720 8 of keying material. Merlin has also confirmed interop with this fix
1721 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
1722 [Merlin Hughes <merlin@baltimore.ie>]
1724 *) Fix lots of warnings.
1725 [Richard Levitte <levitte@stacken.kth.se>]
1727 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
1728 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
1729 [Richard Levitte <levitte@stacken.kth.se>]
1731 *) Fix problems with sizeof(long) == 8.
1732 [Andy Polyakov <appro@fy.chalmers.se>]
1734 *) Change functions to ANSI C.
1737 *) Fix typos in error codes.
1738 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
1740 *) Remove defunct assembler files from Configure.
1743 *) SPARC v8 assembler BIGNUM implementation.
1744 [Andy Polyakov <appro@fy.chalmers.se>]
1746 *) Support for Certificate Policies extension: both print and set.
1747 Various additions to support the r2i method this uses.
1750 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
1751 return a const string when you are expecting an allocated buffer.
1754 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
1755 types DirectoryString and DisplayText.
1758 *) Add code to allow r2i extensions to access the configuration database,
1759 add an LHASH database driver and add several ctx helper functions.
1762 *) Fix an evil bug in bn_expand2() which caused various BN functions to
1763 fail when they extended the size of a BIGNUM.
1766 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
1767 support typesafe stack.
1770 *) Fix typo in SSL_[gs]et_options().
1771 [Nils Frostberg <nils@medcom.se>]
1773 *) Delete various functions and files that belonged to the (now obsolete)
1774 old X509V3 handling code.
1777 *) New Configure option "rsaref".
1780 *) Don't auto-generate pem.h.
1783 *) Introduce type-safe ASN.1 SETs.
1786 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
1787 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
1789 *) Introduce type-safe STACKs. This will almost certainly break lots of code
1790 that links with OpenSSL (well at least cause lots of warnings), but fear
1791 not: the conversion is trivial, and it eliminates loads of evil casts. A
1792 few STACKed things have been converted already. Feel free to convert more.
1793 In the fullness of time, I'll do away with the STACK type altogether.
1796 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
1797 specified in <certfile> by updating the entry in the index.txt file.
1798 This way one no longer has to edit the index.txt file manually for
1799 revoking a certificate. The -revoke option does the gory details now.
1800 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
1802 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
1803 `-text' option at all and this way the `-noout -text' combination was
1804 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
1805 [Ralf S. Engelschall]
1807 *) Make sure a corresponding plain text error message exists for the
1808 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
1809 verify callback function determined that a certificate was revoked.
1810 [Ralf S. Engelschall]
1812 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
1813 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
1814 all available cipers including rc5, which was forgotten until now.
1815 In order to let the testing shell script know which algorithms
1816 are available, a new (up to now undocumented) command
1817 "openssl list-cipher-commands" is used.
1820 *) Bugfix: s_client occasionally would sleep in select() when
1821 it should have checked SSL_pending() first.
1824 *) New functions DSA_do_sign and DSA_do_verify to provide access to
1825 the raw DSA values prior to ASN.1 encoding.
1828 *) Tweaks to Configure
1829 [Niels Poppe <niels@netbox.org>]
1831 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
1835 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
1838 *) New config option to avoid instructions that are illegal on the 80386.
1839 The default code is faster, but requires at least a 486.
1842 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
1843 SSL2_SERVER_VERSION (not used at all) macros, which are now the
1844 same as SSL2_VERSION anyway.
1847 *) New "-showcerts" option for s_client.
1850 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
1851 application. Various cleanups and fixes.
1854 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
1855 modify error routines to work internally. Add error codes and PBE init
1856 to library startup routines.
1859 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
1860 packing functions to asn1 and evp. Changed function names and error
1861 codes along the way.
1864 *) PKCS12 integration: and so it begins... First of several patches to
1865 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
1866 objects to objects.h
1869 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
1870 and display support for Thawte strong extranet extension.
1873 *) Add LinuxPPC support.
1874 [Jeff Dubrule <igor@pobox.org>]
1876 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
1877 bn_div_words in alpha.s.
1878 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
1880 *) Make sure the RSA OAEP test is skipped under -DRSAref because
1881 OAEP isn't supported when OpenSSL is built with RSAref.
1882 [Ulf Moeller <ulf@fitug.de>]
1884 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
1885 so they no longer are missing under -DNOPROTO.
1886 [Soren S. Jorvang <soren@t.dk>]
1889 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
1891 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
1892 doesn't work when the session is reused. Coming soon!
1895 *) Fix a security hole, that allows sessions to be reused in the wrong
1896 context thus bypassing client cert protection! All software that uses
1897 client certs and session caches in multiple contexts NEEDS PATCHING to
1898 allow session reuse! A fuller solution is in the works.
1899 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
1901 *) Some more source tree cleanups (removed obsolete files
1902 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
1903 permission on "config" script to be executable) and a fix for the INSTALL
1905 [Ulf Moeller <ulf@fitug.de>]
1907 *) Remove some legacy and erroneous uses of malloc, free instead of
1909 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
1911 *) Make rsa_oaep_test return non-zero on error.
1912 [Ulf Moeller <ulf@fitug.de>]
1914 *) Add support for native Solaris shared libraries. Configure
1915 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
1916 if someone would make that last step automatic.
1917 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
1919 *) ctx_size was not built with the right compiler during "make links". Fixed.
1922 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
1923 except NULL ciphers". This means the default cipher list will no longer
1924 enable NULL ciphers. They need to be specifically enabled e.g. with
1925 the string "DEFAULT:eNULL".
1928 *) Fix to RSA private encryption routines: if p < q then it would
1929 occasionally produce an invalid result. This will only happen with
1930 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
1933 *) Be less restrictive and allow also `perl util/perlpath.pl
1934 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
1935 because this way one can also use an interpreter named `perl5' (which is
1936 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
1937 installed as `perl').
1938 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1940 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
1941 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1943 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
1944 advapi32.lib to Win32 build and change the pem test comparision
1945 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
1946 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
1947 and crypto/des/ede_cbcm_enc.c.
1950 *) DES quad checksum was broken on big-endian architectures. Fixed.
1953 *) Comment out two functions in bio.h that aren't implemented. Fix up the
1954 Win32 test batch file so it (might) work again. The Win32 test batch file
1955 is horrible: I feel ill....
1958 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
1959 in e_os.h. Audit of header files to check ANSI and non ANSI
1960 sections: 10 functions were absent from non ANSI section and not exported
1961 from Windows DLLs. Fixed up libeay.num for new functions.
1964 *) Make `openssl version' output lines consistent.
1965 [Ralf S. Engelschall]
1967 *) Fix Win32 symbol export lists for BIO functions: Added
1968 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
1969 to ms/libeay{16,32}.def.
1970 [Ralf S. Engelschall]
1972 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
1973 fine under Unix and passes some trivial tests I've now added. But the
1974 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
1975 added to make sure no one expects that this stuff really works in the
1976 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
1977 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
1979 [Ralf S. Engelschall]
1981 *) Fix the generation of two part addresses in perl.
1982 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
1984 *) Add config entry for Linux on MIPS.
1985 [John Tobey <jtobey@channel1.com>]
1987 *) Make links whenever Configure is run, unless we are on Windoze.
1990 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
1991 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
1995 *) Add a useful kludge to allow package maintainers to specify compiler and
1996 other platforms details on the command line without having to patch the
1997 Configure script everytime: One now can use ``perl Configure
1998 <id>:<details>'', i.e. platform ids are allowed to have details appended
1999 to them (seperated by colons). This is treated as there would be a static
2000 pre-configured entry in Configure's %table under key <id> with value
2001 <details> and ``perl Configure <id>'' is called. So, when you want to
2002 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
2003 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
2004 now, which overrides the FreeBSD-elf entry on-the-fly.
2005 [Ralf S. Engelschall]
2007 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
2010 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
2011 on the `perl Configure ...' command line. This way one can compile
2012 OpenSSL libraries with Position Independent Code (PIC) which is needed
2013 for linking it into DSOs.
2014 [Ralf S. Engelschall]
2016 *) Remarkably, export ciphers were totally broken and no-one had noticed!
2020 *) Cleaned up the LICENSE document: The official contact for any license
2021 questions now is the OpenSSL core team under openssl-core@openssl.org.
2022 And add a paragraph about the dual-license situation to make sure people
2023 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
2024 to the OpenSSL toolkit.
2025 [Ralf S. Engelschall]
2027 *) General source tree makefile cleanups: Made `making xxx in yyy...'
2028 display consistent in the source tree and replaced `/bin/rm' by `rm'.
2029 Additonally cleaned up the `make links' target: Remove unnecessary
2030 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
2031 to speed processing and no longer clutter the display with confusing
2032 stuff. Instead only the actually done links are displayed.
2033 [Ralf S. Engelschall]
2035 *) Permit null encryption ciphersuites, used for authentication only. It used
2036 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
2037 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
2041 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
2042 signed attributes when verifying signatures (this would break them),
2043 the detached data encoding was wrong and public keys obtained using
2044 X509_get_pubkey() weren't freed.
2047 *) Add text documentation for the BUFFER functions. Also added a work around
2048 to a Win95 console bug. This was triggered by the password read stuff: the
2049 last character typed gets carried over to the next fread(). If you were
2050 generating a new cert request using 'req' for example then the last
2051 character of the passphrase would be CR which would then enter the first
2055 *) Added the new `Includes OpenSSL Cryptography Software' button as
2056 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
2057 button and can be used by applications based on OpenSSL to show the
2058 relationship to the OpenSSL project.
2059 [Ralf S. Engelschall]
2061 *) Remove confusing variables in function signatures in files
2062 ssl/ssl_lib.c and ssl/ssl.h.
2063 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2065 *) Don't install bss_file.c under PREFIX/include/
2066 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2068 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
2069 functions that return function pointers and has support for NT specific
2070 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
2071 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
2072 unsigned to signed types: this was killing the Win32 compile.
2075 *) Add new certificate file to stack functions,
2076 SSL_add_dir_cert_subjects_to_stack() and
2077 SSL_add_file_cert_subjects_to_stack(). These largely supplant
2078 SSL_load_client_CA_file(), and can be used to add multiple certs easily
2079 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
2080 This means that Apache-SSL and similar packages don't have to mess around
2081 to add as many CAs as they want to the preferred list.
2084 *) Experiment with doxygen documentation. Currently only partially applied to
2086 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
2087 openssl.doxy as the configuration file.
2090 *) Get rid of remaining C++-style comments which strict C compilers hate.
2091 [Ralf S. Engelschall, pointed out by Carlos Amengual]
2093 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
2094 compiled in by default: it has problems with large keys.
2097 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
2098 DH private keys and/or callback functions which directly correspond to
2099 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
2100 is needed for applications which have to configure certificates on a
2101 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
2103 For the RSA certificate situation is makes no difference, but
2104 for the DSA certificate situation this fixes the "no shared cipher"
2105 problem where the OpenSSL cipher selection procedure failed because the
2106 temporary keys were not overtaken from the context and the API provided
2107 no way to reconfigure them.
2108 The new functions now let applications reconfigure the stuff and they
2109 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
2110 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
2111 non-public-API function ssl_cert_instantiate() is used as a helper
2112 function and also to reduce code redundancy inside ssl_rsa.c.
2113 [Ralf S. Engelschall]
2115 *) Move s_server -dcert and -dkey options out of the undocumented feature
2116 area because they are useful for the DSA situation and should be
2117 recognized by the users.
2118 [Ralf S. Engelschall]
2120 *) Fix the cipher decision scheme for export ciphers: the export bits are
2121 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
2122 SSL_EXP_MASK. So, the original variable has to be used instead of the
2123 already masked variable.
2124 [Richard Levitte <levitte@stacken.kth.se>]
2126 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
2127 [Richard Levitte <levitte@stacken.kth.se>]
2129 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
2130 from `int' to `unsigned int' because it's a length and initialized by
2131 EVP_DigestFinal() which expects an `unsigned int *'.
2132 [Richard Levitte <levitte@stacken.kth.se>]
2134 *) Don't hard-code path to Perl interpreter on shebang line of Configure
2135 script. Instead use the usual Shell->Perl transition trick.
2136 [Ralf S. Engelschall]
2138 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
2139 (in addition to RSA certificates) to match the behaviour of `openssl dsa
2140 -noout -modulus' as it's already the case for `openssl rsa -noout
2141 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
2142 currently the public key is printed (a decision which was already done by
2143 `openssl dsa -modulus' in the past) which serves a similar purpose.
2144 Additionally the NO_RSA no longer completely removes the whole -modulus
2145 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
2147 [Ralf S. Engelschall]
2149 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
2150 BIO. See the source (crypto/evp/bio_ok.c) for more info.
2151 [Arne Ansper <arne@ats.cyber.ee>]
2153 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
2154 to be added. Now both 'req' and 'ca' can use new objects defined in the
2158 *) Add cool BIO that does syslog (or event log on NT).
2159 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
2161 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
2162 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
2163 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
2164 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
2167 *) Add preliminary config info for new extension code.
2170 *) Make RSA_NO_PADDING really use no padding.
2171 [Ulf Moeller <ulf@fitug.de>]
2173 *) Generate errors when private/public key check is done.
2176 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
2177 for some CRL extensions and new objects added.
2180 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
2181 key usage extension and fuller support for authority key id.
2184 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
2185 padding method for RSA, which is recommended for new applications in PKCS
2186 #1 v2.0 (RFC 2437, October 1998).
2187 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
2188 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
2189 against Bleichbacher's attack on RSA.
2190 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
2193 *) Updates to the new SSL compression code
2194 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2196 *) Fix so that the version number in the master secret, when passed
2197 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
2198 (because the server will not accept higher), that the version number
2199 is 0x03,0x01, not 0x03,0x00
2200 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2202 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
2203 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
2204 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
2207 *) Support for RAW extensions where an arbitrary extension can be
2208 created by including its DER encoding. See apps/openssl.cnf for
2212 *) Make sure latest Perl versions don't interpret some generated C array
2213 code as Perl array code in the crypto/err/err_genc.pl script.
2214 [Lars Weber <3weber@informatik.uni-hamburg.de>]
2216 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
2217 not many people have the assembler. Various Win32 compilation fixes and
2218 update to the INSTALL.W32 file with (hopefully) more accurate Win32
2222 *) Modify configure script 'Configure' to automatically create crypto/date.h
2223 file under Win32 and also build pem.h from pem.org. New script
2224 util/mkfiles.pl to create the MINFO file on environments that can't do a
2225 'make files': perl util/mkfiles.pl >MINFO should work.
2228 *) Major rework of DES function declarations, in the pursuit of correctness
2229 and purity. As a result, many evil casts evaporated, and some weirdness,
2230 too. You may find this causes warnings in your code. Zapping your evil
2231 casts will probably fix them. Mostly.
2234 *) Fix for a typo in asn1.h. Bug fix to object creation script
2235 obj_dat.pl. It considered a zero in an object definition to mean
2236 "end of object": none of the objects in objects.h have any zeros
2237 so it wasn't spotted.
2238 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
2240 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
2241 Masking (CBCM). In the absence of test vectors, the best I have been able
2242 to do is check that the decrypt undoes the encrypt, so far. Send me test
2243 vectors if you have them.
2246 *) Correct calculation of key length for export ciphers (too much space was
2247 allocated for null ciphers). This has not been tested!
2250 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
2251 message is now correct (it understands "crypto" and "ssl" on its
2252 command line). There is also now an "update" option. This will update
2253 the util/ssleay.num and util/libeay.num files with any new functions.
2255 perl util/mkdef.pl crypto ssl update
2256 it will update them.
2259 *) Overhauled the Perl interface (perl/*):
2260 - ported BN stuff to OpenSSL's different BN library
2261 - made the perl/ source tree CVS-aware
2262 - renamed the package from SSLeay to OpenSSL (the files still contain
2263 their history because I've copied them in the repository)
2264 - removed obsolete files (the test scripts will be replaced
2265 by better Test::Harness variants in the future)
2266 [Ralf S. Engelschall]
2268 *) First cut for a very conservative source tree cleanup:
2269 1. merge various obsolete readme texts into doc/ssleay.txt
2270 where we collect the old documents and readme texts.
2271 2. remove the first part of files where I'm already sure that we no
2272 longer need them because of three reasons: either they are just temporary
2273 files which were left by Eric or they are preserved original files where
2274 I've verified that the diff is also available in the CVS via "cvs diff
2275 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
2276 the crypto/md/ stuff).
2277 [Ralf S. Engelschall]
2279 *) More extension code. Incomplete support for subject and issuer alt
2280 name, issuer and authority key id. Change the i2v function parameters
2281 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
2282 what that's for :-) Fix to ASN1 macro which messed up
2283 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
2286 *) Preliminary support for ENUMERATED type. This is largely copied from the
2290 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
2291 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2293 *) Make sure `make rehash' target really finds the `openssl' program.
2294 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2296 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
2297 like to hear about it if this slows down other processors.
2300 *) Add CygWin32 platform information to Configure script.
2301 [Alan Batie <batie@aahz.jf.intel.com>]
2303 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
2304 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
2306 *) New program nseq to manipulate netscape certificate sequences
2309 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
2313 *) Fixes to BN code. Previously the default was to define BN_RECURSION
2314 but the BN code had some problems that would cause failures when
2315 doing certificate verification and some other functions.
2316 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2318 *) Add ASN1 and PEM code to support netscape certificate sequences.
2321 *) Add ASN1 and PEM code to support netscape certificate sequences.
2324 *) Add several PKIX and private extended key usage OIDs.
2327 *) Modify the 'ca' program to handle the new extension code. Modify
2328 openssl.cnf for new extension format, add comments.
2331 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
2332 and add a sample to openssl.cnf so req -x509 now adds appropriate
2336 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
2337 error code, add initial support to X509_print() and x509 application.
2340 *) Takes a deep breath and start addding X509 V3 extension support code. Add
2341 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
2342 stuff is currently isolated and isn't even compiled yet.
2345 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
2346 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
2347 Removed the versions check from X509 routines when loading extensions:
2348 this allows certain broken certificates that don't set the version
2349 properly to be processed.
2352 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
2353 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
2354 can still be regenerated with "make depend".
2357 *) Spelling mistake in C version of CAST-128.
2358 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
2360 *) Changes to the error generation code. The perl script err-code.pl
2361 now reads in the old error codes and retains the old numbers, only
2362 adding new ones if necessary. It also only changes the .err files if new
2363 codes are added. The makefiles have been modified to only insert errors
2364 when needed (to avoid needlessly modifying header files). This is done
2365 by only inserting errors if the .err file is newer than the auto generated
2366 C file. To rebuild all the error codes from scratch (the old behaviour)
2367 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
2368 or delete all the .err files.
2371 *) CAST-128 was incorrectly implemented for short keys. The C version has
2372 been fixed, but is untested. The assembler versions are also fixed, but
2373 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
2374 to regenerate it if needed.
2375 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
2376 Hagino <itojun@kame.net>]
2378 *) File was opened incorrectly in randfile.c.
2379 [Ulf Möller <ulf@fitug.de>]
2381 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
2382 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
2383 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
2384 al: it's just almost always a UTCTime. Note this patch adds new error
2385 codes so do a "make errors" if there are problems.
2388 *) Correct Linux 1 recognition in config.
2389 [Ulf Möller <ulf@fitug.de>]
2391 *) Remove pointless MD5 hash when using DSA keys in ca.
2392 [Anonymous <nobody@replay.com>]
2394 *) Generate an error if given an empty string as a cert directory. Also
2395 generate an error if handed NULL (previously returned 0 to indicate an
2396 error, but didn't set one).
2397 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
2399 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
2402 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
2403 parameters. This was causing a warning which killed off the Win32 compile.
2406 *) Remove C++ style comments from crypto/bn/bn_local.h.
2407 [Neil Costigan <neil.costigan@celocom.com>]
2409 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
2410 based on a text string, looking up short and long names and finally
2411 "dot" format. The "dot" format stuff didn't work. Added new function
2412 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
2413 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
2414 OID is not part of the table.
2417 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
2418 X509_LOOKUP_by_alias().
2421 *) Sort openssl functions by name.
2424 *) Get the gendsa program working (hopefully) and add it to app list. Remove
2425 encryption from sample DSA keys (in case anyone is interested the password
2429 *) Make _all_ *_free functions accept a NULL pointer.
2430 [Frans Heymans <fheymans@isaserver.be>]
2432 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
2434 [Anonymous <nobody@replay.com>]
2436 *) s_server should send the CAfile as acceptable CAs, not its own cert.
2437 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2439 *) Don't blow it for numeric -newkey arguments to apps/req.
2440 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2442 *) Temp key "for export" tests were wrong in s3_srvr.c.
2443 [Anonymous <nobody@replay.com>]
2445 *) Add prototype for temp key callback functions
2446 SSL_CTX_set_tmp_{rsa,dh}_callback().
2449 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
2450 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
2453 *) X509_name_add_entry() freed the wrong thing after an error.
2454 [Arne Ansper <arne@ats.cyber.ee>]
2456 *) rsa_eay.c would attempt to free a NULL context.
2457 [Arne Ansper <arne@ats.cyber.ee>]
2459 *) BIO_s_socket() had a broken should_retry() on Windoze.
2460 [Arne Ansper <arne@ats.cyber.ee>]
2462 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
2463 [Arne Ansper <arne@ats.cyber.ee>]
2465 *) Make sure the already existing X509_STORE->depth variable is initialized
2466 in X509_STORE_new(), but document the fact that this variable is still
2467 unused in the certificate verification process.
2468 [Ralf S. Engelschall]
2470 *) Fix the various library and apps files to free up pkeys obtained from
2471 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
2474 *) Fix reference counting in X509_PUBKEY_get(). This makes
2475 demos/maurice/example2.c work, amongst others, probably.
2476 [Steve Henson and Ben Laurie]
2478 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
2479 `openssl' and second, the shortcut symlinks for the `openssl <command>'
2480 are no longer created. This way we have a single and consistent command
2481 line interface `openssl <command>', similar to `cvs <command>'.
2482 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
2484 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
2485 BIT STRING wrapper always have zero unused bits.
2488 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
2491 *) Make the top-level INSTALL documentation easier to understand.
2494 *) Makefiles updated to exit if an error occurs in a sub-directory
2495 make (including if user presses ^C) [Paul Sutton]
2497 *) Make Montgomery context stuff explicit in RSA data structure.
2500 *) Fix build order of pem and err to allow for generated pem.h.
2503 *) Fix renumbering bug in X509_NAME_delete_entry().
2506 *) Enhanced the err-ins.pl script so it makes the error library number
2507 global and can add a library name. This is needed for external ASN1 and
2508 other error libraries.
2511 *) Fixed sk_insert which never worked properly.
2514 *) Fix ASN1 macros so they can handle indefinite length construted
2515 EXPLICIT tags. Some non standard certificates use these: they can now
2519 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
2520 into a single doc/ssleay.txt bundle. This way the information is still
2521 preserved but no longer messes up this directory. Now it's new room for
2522 the new set of documenation files.
2523 [Ralf S. Engelschall]
2525 *) SETs were incorrectly DER encoded. This was a major pain, because they
2526 shared code with SEQUENCEs, which aren't coded the same. This means that
2527 almost everything to do with SETs or SEQUENCEs has either changed name or
2528 number of arguments.
2529 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
2531 *) Fix test data to work with the above.
2534 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
2535 was already fixed by Eric for 0.9.1 it seems.
2536 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
2538 *) Autodetect FreeBSD3.
2541 *) Fix various bugs in Configure. This affects the following platforms:
2545 unixware-2.0-pentium
2549 *) Eliminate generated files from CVS. Reorder tests to regenerate files
2550 before they are needed.
2553 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
2557 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
2559 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
2560 changed SSLeay to OpenSSL in version strings.
2561 [Ralf S. Engelschall]
2563 *) Some fixups to the top-level documents.
2566 *) Fixed the nasty bug where rsaref.h was not found under compile-time
2567 because the symlink to include/ was missing.
2568 [Ralf S. Engelschall]
2570 *) Incorporated the popular no-RSA/DSA-only patches
2571 which allow to compile a RSA-free SSLeay.
2572 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
2574 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
2575 when "ssleay" is still not found.
2576 [Ralf S. Engelschall]
2578 *) Added more platforms to Configure: Cray T3E, HPUX 11,
2579 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
2581 *) Updated the README file.
2582 [Ralf S. Engelschall]
2584 *) Added various .cvsignore files in the CVS repository subdirs
2585 to make a "cvs update" really silent.
2586 [Ralf S. Engelschall]
2588 *) Recompiled the error-definition header files and added
2589 missing symbols to the Win32 linker tables.
2590 [Ralf S. Engelschall]
2592 *) Cleaned up the top-level documents;
2593 o new files: CHANGES and LICENSE
2594 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
2595 o merged COPYRIGHT into LICENSE
2596 o removed obsolete TODO file
2597 o renamed MICROSOFT to INSTALL.W32
2598 [Ralf S. Engelschall]
2600 *) Removed dummy files from the 0.9.1b source tree:
2601 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
2602 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
2603 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
2604 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
2605 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
2606 [Ralf S. Engelschall]
2608 *) Added various platform portability fixes.
2611 *) The Genesis of the OpenSSL rpject:
2612 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
2613 Young and Tim J. Hudson created while they were working for C2Net until
2615 [The OpenSSL Project]
2618 Changes between 0.9.0b and 0.9.1b [not released]
2620 *) Updated a few CA certificates under certs/
2623 *) Changed some BIGNUM api stuff.
2626 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
2627 DGUX x86, Linux Alpha, etc.
2630 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
2631 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
2635 *) Add -strparse option to asn1pars program which parses nested
2637 [Dr Stephen Henson <shenson@bigfoot.com>]
2639 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
2642 *) DSA fix for "ca" program.
2645 *) Added "-genkey" option to "dsaparam" program.
2648 *) Added RIPE MD160 (rmd160) message digest.
2651 *) Added -a (all) option to "ssleay version" command.
2654 *) Added PLATFORM define which is the id given to Configure.
2657 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
2660 *) Extended the ASN.1 parser routines.
2663 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
2666 *) Added a BN_CTX to the BN library.
2669 *) Fixed the weak key values in DES library
2672 *) Changed API in EVP library for cipher aliases.
2675 *) Added support for RC2/64bit cipher.
2678 *) Converted the lhash library to the crypto/mem.c functions.
2681 *) Added more recognized ASN.1 object ids.
2684 *) Added more RSA padding checks for SSL/TLS.
2687 *) Added BIO proxy/filter functionality.
2690 *) Added extra_certs to SSL_CTX which can be used
2691 send extra CA certificates to the client in the CA cert chain sending
2692 process. It can be configured with SSL_CTX_add_extra_chain_cert().
2695 *) Now Fortezza is denied in the authentication phase because
2696 this is key exchange mechanism is not supported by SSLeay at all.
2699 *) Additional PKCS1 checks.
2702 *) Support the string "TLSv1" for all TLS v1 ciphers.
2705 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
2706 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
2709 *) Fixed a few memory leaks.
2712 *) Fixed various code and comment typos.
2715 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
2716 bytes sent in the client random.
