OpenSSL CHANGES
_______________
- Changes between 0.9.6 and 0.9.7 [xx XXX 2001]
-
- Both OpenSSL 0.9.6a (bugfix release, 5 Apr 2001) and OpenSSL 0.9.7
- are based on OpenSSL 0.9.6.
- Change log entries are tagged as follows:
- -) applies to 0.9.6a (/0.9.6b) only
- *) applies to 0.9.6a (/0.9.6b) and 0.9.7
- +) applies to 0.9.7 only
-
- *) Change all calls to low level digest routines in the library and
- applications to use EVP. Add missing calls to HMAC_cleanup() and
- don't assume HMAC_CTX can be copied using memcpy().
- [Verdon Walker <VWalker@novell.com>, Steve Henson]
-
- +) Add the possibility to control engines through control names but with
- arbitrary arguments instead of just a string.
- Change the key loaders to take a UI_METHOD instead of a callback
- function pointer. NOTE: this breaks binary compatibility with earlier
- versions of OpenSSL [engine].
- Addapt the nCipher code for these new conditions and add a card insertion
- callback.
- [Richard Levitte]
+ Changes between 0.9.6b and 0.9.6c [XX xxx XXXX]
- +) Enhance the general user interface with mechanisms to better support
- dialog box interfaces, application-defined prompts, the possibility
- to use defaults (for example default passwords from somewhere else)
- and interrupts/cancelations.
- [Richard Levitte]
+ *) Rabin-Miller test analyses assume uniformly distributed witnesses,
+ so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
+ followed by modular reduction.
+ [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
+
+ *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
+ requivalent based on BN_pseudo_rand() instead of BN_rand().
+ [Bodo Moeller]
+
+ *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
+ This function was broken, as the check for a new client hello message
+ to handle SGC did not allow these large messages.
+ (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
+ [Lutz Jaenicke]
+
+ *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
+ [Lutz Jaenicke]
+
+ *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
+ for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
+ [Lutz Jaenicke]
+
+ *) Rework the configuration and shared library support for Tru64 Unix.
+ The configuration part makes use of modern compiler features and
+ still retains old compiler behavior for those that run older versions
+ of the OS. The shared library support part includes a variant that
+ uses the RPATH feature, and is available through the speciel
+ configuration target "alpha-cc-rpath", which will never be selected
+ automatically.
+ [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
+
+ *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
+ with the same message size as in ssl3_get_certificate_request().
+ Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
+ messages might inadvertently be reject as too long.
+ [Petr Lampa <lampa@fee.vutbr.cz>]
+
+ *) Modified SSL library such that the verify_callback that has been set
+ specificly for an SSL object with SSL_set_verify() is actually being
+ used. Before the change, a verify_callback set with this function was
+ ignored and the verify_callback() set in the SSL_CTX at the time of
+ the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
+ to allow the necessary settings.
+ [Lutz Jaenicke]
+
+ *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
+ explicitely to NULL, as at least on Solaris 8 this seems not always to be
+ done automatically (in contradiction to the requirements of the C
+ standard). This made problems when used from OpenSSH.
+ [Lutz Jaenicke]
+
+ *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
+ dh->length and always used
+
+ BN_rand_range(priv_key, dh->p).
+
+ BN_rand_range() is not necessary for Diffie-Hellman, and this
+ specific range makes Diffie-Hellman unnecessarily inefficient if
+ dh->length (recommended exponent length) is much smaller than the
+ length of dh->p. We could use BN_rand_range() if the order of
+ the subgroup was stored in the DH structure, but we only have
+ dh->length.
+
+ So switch back to
+
+ BN_rand(priv_key, l, ...)
+
+ where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
+ otherwise.
+ [Bodo Moeller]
+
+ *) In
+
+ RSA_eay_public_encrypt
+ RSA_eay_private_decrypt
+ RSA_eay_private_encrypt (signing)
+ RSA_eay_public_decrypt (signature verification)
+
+ (default implementations for RSA_public_encrypt,
+ RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
+ always reject numbers >= n.
+ [Bodo Moeller]
+
+ *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
+ to synchronize access to 'locking_thread'. This is necessary on
+ systems where access to 'locking_thread' (an 'unsigned long'
+ variable) is not atomic.
+ [Bodo Moeller]
+
+ *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
+ *before* setting the 'crypto_lock_rand' flag. The previous code had
+ a race condition if 0 is a valid thread ID.
+ [Travis Vitek <vitek@roguewave.com>]
+
+ Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
+
+ *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
+ to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
+ Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
+ PRNG state recovery was possible based on the output of
+ one PRNG request appropriately sized to gain knowledge on
+ 'md' followed by enough consecutive 1-byte PRNG requests
+ to traverse all of 'state'.
+
+ 1. When updating 'md_local' (the current thread's copy of 'md')
+ during PRNG output generation, hash all of the previous
+ 'md_local' value, not just the half used for PRNG output.
+
+ 2. Make the number of bytes from 'state' included into the hash
+ independent from the number of PRNG bytes requested.
+
+ The first measure alone would be sufficient to avoid
+ Markku-Juhani's attack. (Actually it had never occurred
+ to me that the half of 'md_local' used for chaining was the
+ half from which PRNG output bytes were taken -- I had always
+ assumed that the secret half would be used.) The second
+ measure makes sure that additional data from 'state' is never
+ mixed into 'md_local' in small portions; this heuristically
+ further strengthens the PRNG.
+ [Bodo Moeller]
+
+ *) Fix crypto/bn/asm/mips3.s.
+ [Andy Polyakov]
+
+ *) When only the key is given to "enc", the IV is undefined. Print out
+ an error message in this case.
+ [Lutz Jaenicke]
+
+ *) Handle special case when X509_NAME is empty in X509 printing routines.
+ [Steve Henson]
+
+ *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
+ positive and less than q.
+ [Bodo Moeller]
*) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
used: it isn't thread safe and the add_lock_callback should handle
ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
[Bodo Moeller]
- +) Tidy up PKCS#12 attribute handling. Add support for the CSP name
- attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
- [Steve Henson]
-
*) Fix OAEP check.
[Ulf Möller, Bodo Möller]
(previously it was 1024).
[Bodo Moeller]
- +) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
- tidy up some unecessarily weird code in 'sk_new()').
- [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
-
- +) Change the key loading routines for ENGINEs to use the same kind
- callback (pem_password_cb) as all other routines that need this
- kind of callback.
- [Richard Levitte]
-
*) Fix for compatibility mode trust settings: ignore trust settings
unless some valid trust or reject settings are present.
[Steve Henson]
*) Fix for blowfish EVP: its a variable length cipher.
[Steve Henson]
- +) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
- 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
- than this minimum value is recommended.
- [Lutz Jaenicke]
-
- +) New random seeder for OpenVMS, using the system process statistics
- that are easily reachable.
- [Richard Levitte]
-
- +) Windows apparently can't transparently handle global
- variables defined in DLLs. Initialisations such as:
-
- const ASN1_ITEM *it = &ASN1_INTEGER_it;
-
- wont compile. This is used by the any applications that need to
- delcare their own ASN1 modules. This was fixed by adding the option
- EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
- needed for static libraries under Win32.
- [Steve Henson]
-
- +) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
- setting of purpose and trust fields. New X509_STORE trust and
- purpose functions and tidy up setting in other SSL functions.
- [Steve Henson]
-
- +) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
- structure. These are inherited by X509_STORE_CTX when it is
- initialised. This allows various defaults to be set in the
- X509_STORE structure (such as flags for CRL checking and custom
- purpose or trust settings) for functions which only use X509_STORE_CTX
- internally such as S/MIME.
-
- Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
- trust settings if they are not set in X509_STORE. This allows X509_STORE
- purposes and trust (in S/MIME for example) to override any set by default.
-
- Add command line options for CRL checking to smime, s_client and s_server
- applications.
- [Steve Henson]
-
- +) Initial CRL based revocation checking. If the CRL checking flag(s)
- are set then the CRL is looked up in the X509_STORE structure and
- its validity and signature checked, then if the certificate is found
- in the CRL the verify fails with a revoked error.
-
- Various new CRL related callbacks added to X509_STORE_CTX structure.
-
- Command line options added to 'verify' application to support this.
-
- This needs some additional work, such as being able to handle multiple
- CRLs with different times, extension based lookup (rather than just
- by subject name) and ultimately more complete V2 CRL extension
- handling.
+ *) Fix various bugs related to DSA S/MIME verification. Handle missing
+ parameters in DSA public key structures and return an error in the
+ DSA routines if parameters are absent.
[Steve Henson]
- +) Add a general user interface API (crypto/ui/). This is designed
- to replace things like des_read_password and friends (backward
- compatibility functions using this new API are provided).
- The purpose is to remove prompting functions from the DES code
- section as well as provide for prompting through dialog boxes in
- a window system and the like.
- [Richard Levitte]
-
*) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
in the current directory if neither $RANDFILE nor $HOME was set.
RAND_file_name() in 0.9.6a returned NULL in this case. This has
For Windows, we use "C:"; on other platforms, we still require
environment variables.
- +) Add "ex_data" support to ENGINE so implementations can add state at a
- per-structure level rather than having to store it globally.
- [Geoff]
-
- +) Make it possible for ENGINE structures to be copied when retrieved by
- ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
- This causes the "original" ENGINE structure to act like a template,
- analogous to the RSA vs. RSA_METHOD type of separation. Because of this
- operational state can be localised to each ENGINE structure, despite the
- fact they all share the same "methods". New ENGINE structures returned in
- this case have no functional references and the return value is the single
- structural reference. This matches the single structural reference returned
- by ENGINE_by_id() normally, when it is incremented on the pre-existing
- ENGINE structure.
- [Geoff]
-
- *) Fix various bugs related to DSA S/MIME verification. Handle missing
- parameters in DSA public key structures and return an error in the
- DSA routines if parameters are absent.
- [Steve Henson]
-
- +) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
- needs to match any other type at all we need to manually clear the
- tag cache.
- [Steve Henson]
-
- +) Changes to the "openssl engine" utility to include;
- - verbosity levels ('-v', '-vv', and '-vvv') that provide information
- about an ENGINE's available control commands.
- - executing control commands from command line arguments using the
- '-pre' and '-post' switches. '-post' is only used if '-t' is
- specified and the ENGINE is successfully initialised. The syntax for
- the individual commands are colon-separated, for example;
- openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
- [Geoff]
-
- +) New dynamic control command support for ENGINEs. ENGINEs can now
- declare their own commands (numbers), names (strings), descriptions,
- and input types for run-time discovery by calling applications. A
- subset of these commands are implicitly classed as "executable"
- depending on their input type, and only these can be invoked through
- the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
- can be based on user input, config files, etc). The distinction is
- that "executable" commands cannot return anything other than a boolean
- result and can only support numeric or string input, whereas some
- discoverable commands may only be for direct use through
- ENGINE_ctrl(), eg. supporting the exchange of binary data, function
- pointers, or other custom uses. The "executable" commands are to
- support parameterisations of ENGINE behaviour that can be
- unambiguously defined by ENGINEs and used consistently across any
- OpenSSL-based application. Commands have been added to all the
- existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
- control over shared-library paths without source code alterations.
- [Geoff]
-
- +) Changed all ENGINE implementations to dynamically allocate their
- ENGINEs rather than declaring them statically. Apart from this being
- necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
- this also allows the implementations to compile without using the
- internal engine_int.h header.
- [Geoff]
-
- +) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
- 'const' value. Any code that should be able to modify a RAND_METHOD
- should already have non-const pointers to it (ie. they should only
- modify their own ones).
- [Geoff]
-
- +) Made a variety of little tweaks to the ENGINE code.
- - "atalla" and "ubsec" string definitions were moved from header files
- to C code. "nuron" string definitions were placed in variables
- rather than hard-coded - allowing parameterisation of these values
- later on via ctrl() commands.
- - Removed unused "#if 0"'d code.
- - Fixed engine list iteration code so it uses ENGINE_free() to release
- structural references.
- - Constified the RAND_METHOD element of ENGINE structures.
- - Constified various get/set functions as appropriate and added
- missing functions (including a catch-all ENGINE_cpy that duplicates
- all ENGINE values onto a new ENGINE except reference counts/state).
- - Removed NULL parameter checks in get/set functions. Setting a method
- or function to NULL is a way of cancelling out a previously set
- value. Passing a NULL ENGINE parameter is just plain stupid anyway
- and doesn't justify the extra error symbols and code.
- - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
- flags from engine_int.h to engine.h.
- - Changed prototypes for ENGINE handler functions (init(), finish(),
- ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
- [Geoff]
-
*) Move 'if (!initialized) RAND_poll()' into regions protected by
CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
having multiple threads call RAND_poll() concurrently.
that they do not hold after the first thread unsets add_do_not_lock).
[Bodo Moeller]
- +) Implement binary inversion algorithm for BN_mod_inverse in addition
- to the algorithm using long divison. The binary algorithm can be
- used only if the modulus is odd. On 32-bit systems, it is faster
- only for relatively small moduli (roughly 20-30% for 128-bit moduli,
- roughly 5-15% for 256-bit moduli), so we use it only for moduli
- up to 450 bits. In 64-bit environments, the binary algorithm
- appears to be advantageous for much longer moduli; here we use it
- for moduli up to 2048 bits.
- [Bodo Moeller]
-
*) Change bctest again: '-x' expressions are not available in all
versions of 'test'.
[Bodo Moeller]
- -) OpenSSL 0.9.6a released [5 Apr 2001]
+ Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
*) Fix a couple of memory leaks in PKCS7_dataDecode()
[Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
CygWin.
[Richard Levitte]
- +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
- could not support the combine flag in choice fields.
- [Steve Henson]
-
- -) Fix for asn1_GetSequence() for indefinite length constructed data.
+ *) Fix for asn1_GetSequence() for indefinite length constructed data.
If SEQUENCE is length is indefinite just set c->slen to the total
amount of data available.
[Steve Henson, reported by shige@FreeBSD.org]
*) Disabled incorrect Alpha assembler code.
[Richard Levitte]
- -) Fix PKCS#7 decode routines so they correctly update the length
+ *) Fix PKCS#7 decode routines so they correctly update the length
after reading an EOC for the EXPLICIT tag.
[Steve Henson]
[This change does not apply to 0.9.7.]
it when found.
[Tim Rice <tim@multitalents.net> via Richard Levitte]
- +) Add a 'copy_extensions' option to the 'ca' utility. This copies
- extensions from a certificate request to the certificate.
- [Steve Henson]
-
- +) Allow multiple 'certopt' and 'nameopt' options to be separated
- by commas. Add 'namopt' and 'certopt' options to the 'ca' config
- file: this allows the display of the certificate about to be
- signed to be customised, to allow certain fields to be included
- or excluded and extension details. The old system didn't display
- multicharacter strings properly, omitted fields not in the policy
- and couldn't display additional details such as extensions.
- [Steve Henson]
-
*) Fix memory leaks in err.c: free err_data string if necessary;
don't write to the wrong index in ERR_set_error_data.
[Bodo Moeller]
- +) Function EC_POINTs_mul for simultaneous scalar multiplication
- of an arbitrary number of elliptic curve points, optionally
- including the generator defined for the EC_GROUP.
- EC_POINT_mul is a simple wrapper function for the typical case
- that the point list has just one item (besides the optional
- generator).
- [Bodo Moeller]
-
- +) First EC_METHODs for curves over GF(p):
-
- EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
- operations and provides various method functions that can also
- operate with faster implementations of modular arithmetic.
-
- EC_GFp_mont_method() reuses most functions that are part of
- EC_GFp_simple_method, but uses Montgomery arithmetic.
-
- [Bodo Moeller; point addition and point doubling
- implementation directly derived from source code provided by
- Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
-
- +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
- crypto/ec/ec_lib.c):
-
- Curves are EC_GROUP objects (with an optional group generator)
- based on EC_METHODs that are built into the library.
-
- Points are EC_POINT objects based on EC_GROUP objects.
-
- Most of the framework would be able to handle curves over arbitrary
- finite fields, but as there are no obvious types for fields other
- than GF(p), some functions are limited to that for now.
- [Bodo Moeller]
-
- +) Add the -HTTP option to s_server. It is similar to -WWW, but requires
- that the file contains a complete HTTP response.
- [Richard Levitte]
-
- +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
- change the def and num file printf format specifier from "%-40sXXX"
- to "%-39s XXX". The latter will always guarantee a space after the
- field while the former will cause them to run together if the field
- is 40 of more characters long.
- [Steve Henson]
-
- +) Constify the cipher and digest 'method' functions and structures
- and modify related functions to take constant EVP_MD and EVP_CIPHER
- pointers.
- [Steve Henson]
-
*) Implement ssl23_peek (analogous to ssl23_read), which previously
did not exist.
[Bodo Moeller]
*) Replace rdtsc with _emit statements for VC++ version 5.
[Jeremy Cooper <jeremy@baymoo.org>]
- +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
- in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
- [Bodo Moeller]
-
- +) Modify EVP_Digest*() routines so they now return values. Although the
- internal software routines can never fail additional hardware versions
- might.
- [Steve Henson]
-
- +) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
-
- Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
- (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
-
- ASN1 error codes
- ERR_R_NESTED_ASN1_ERROR
- ...
- ERR_R_MISSING_ASN1_EOS
- were 4 .. 9, conflicting with
- ERR_LIB_RSA (= ERR_R_RSA_LIB)
- ...
- ERR_LIB_PEM (= ERR_R_PEM_LIB).
- They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
-
- Add new error code 'ERR_R_INTERNAL_ERROR'.
- [Bodo Moeller]
-
- +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
- suffices.
- [Bodo Moeller]
-
- +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
- sets the subject name for a new request or supersedes the
- subject name in a given request. Formats that can be parsed are
- 'CN=Some Name, OU=myOU, C=IT'
- and
- 'CN=Some Name/OU=myOU/C=IT'.
-
- Add options '-batch' and '-verbose' to 'openssl req'.
- [Massimiliano Pala <madwolf@hackmasters.net>]
-
*) Make it possible to reuse SSLv2 sessions.
[Richard Levitte]
- +) Introduce the possibility to access global variables through
- functions on platform were that's the best way to handle exporting
- global variables in shared libraries. To enable this functionality,
- one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
- "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
- is normally done by Configure or something similar).
-
- To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
- in the source file (foo.c) like this:
-
- OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
- OPENSSL_IMPLEMENT_GLOBAL(double,bar);
-
- To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
- and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
-
- OPENSSL_DECLARE_GLOBAL(int,foo);
- #define foo OPENSSL_GLOBAL_REF(foo)
- OPENSSL_DECLARE_GLOBAL(double,bar);
- #define bar OPENSSL_GLOBAL_REF(bar)
-
- The #defines are very important, and therefore so is including the
- header file everywere where the defined globals are used.
-
- The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
- of ASN.1 items, but that structure is a bt different.
-
- The largest change is in util/mkdef.pl which has been enhanced with
- better and easier to understand logic to choose which symbols should
- go into the Windows .def files as well as a number of fixes and code
- cleanup (among others, algorithm keywords are now sorted
- lexicographically to avoid constant rewrites).
- [Richard Levitte]
-
*) In copy_email() check for >= 0 as a return value for
X509_NAME_get_index_by_NID() since 0 is a valid index.
[Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
- +) In BN_div() keep a copy of the sign of 'num' before writing the
- result to 'rm' because if rm==num the value will be overwritten
- and produce the wrong result if 'num' is negative: this caused
- problems with BN_mod() and BN_nnmod().
- [Steve Henson]
-
- +) Function OCSP_request_verify(). This checks the signature on an
- OCSP request and verifies the signer certificate. The signer
- certificate is just checked for a generic purpose and OCSP request
- trust settings.
- [Steve Henson]
-
- +) Add OCSP_check_validity() function to check the validity of OCSP
- responses. OCSP responses are prepared in real time and may only
- be a few seconds old. Simply checking that the current time lies
- between thisUpdate and nextUpdate max reject otherwise valid responses
- caused by either OCSP responder or client clock innacuracy. Instead
- we allow thisUpdate and nextUpdate to fall within a certain period of
- the current time. The age of the response can also optionally be
- checked. Two new options -validity_period and -status_age added to
- ocsp utility.
- [Steve Henson]
-
- +) If signature or public key algorithm is unrecognized print out its
- OID rather that just UNKOWN.
- [Steve Henson]
-
*) Avoid coredump with unsupported or invalid public keys by checking if
X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
PKCS7_verify() fails with non detached data.
[Steve Henson]
- +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
- OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
- ID to be generated from the issuer certificate alone which can then be
- passed to OCSP_id_issuer_cmp().
- [Steve Henson]
-
- +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
- ASN1 modules to export functions returning ASN1_ITEM pointers
- instead of the ASN1_ITEM structures themselves. This adds several
- new macros which allow the underlying ASN1 function/structure to
- be accessed transparently. As a result code should not use ASN1_ITEM
- references directly (such as &X509_it) but instead use the relevant
- macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
- use of the new ASN1 code on platforms where exporting structures
- is problematical (for example in shared libraries) but exporting
- functions returning pointers to structures is not.
- [Steve Henson]
-
- +) Add support for overriding the generation of SSL/TLS session IDs.
- These callbacks can be registered either in an SSL_CTX or per SSL.
- The purpose of this is to allow applications to control, if they wish,
- the arbitrary values chosen for use as session IDs, particularly as it
- can be useful for session caching in multiple-server environments. A
- command-line switch for testing this (and any client code that wishes
- to use such a feature) has been added to "s_server".
- [Geoff Thorpe, Lutz Jaenicke]
-
- +) Modify mkdef.pl to recognise and parse prprocessor conditionals
- of the form '#if defined(...) || defined(...) || ...' and
- '#if !defined(...) && !defined(...) && ...'. This also avoids
- the growing number of special cases it was previously handling.
- [Richard Levitte]
-
*) Don't use getenv in library functions when run as setuid/setgid.
New function OPENSSL_issetugid().
[Ulf Moeller]
- +) Make all configuration macros available for application by making
- sure they are available in opensslconf.h, by giving them names starting
- with "OPENSSL_" to avoid conflicts with other packages and by making
- sure e_os2.h will cover all platform-specific cases together with
- opensslconf.h.
- Additionally, it is now possible to define configuration/platform-
- specific names (called "system identities"). In the C code, these
- are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
- macro with the name beginning with "OPENSSL_SYS_", which is determined
- from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
- what is available.
- [Richard Levitte]
-
- +) New option -set_serial to 'req' and 'x509' this allows the serial
- number to use to be specified on the command line. Previously self
- signed certificates were hard coded with serial number 0 and the
- CA options of 'x509' had to use a serial number in a file which was
- auto incremented.
- [Steve Henson]
-
*) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
due to incorrect handling of multi-threading:
assumption that thread ID 0 is impossible).
[Bodo Moeller]
- +) New options to 'ca' utility to support V2 CRL entry extensions.
- Currently CRL reason, invalidity date and hold instruction are
- supported. Add new CRL extensions to V3 code and some new objects.
- [Steve Henson]
-
*) Add "-rand" option also to s_client and s_server.
[Lutz Jaenicke]
- +) New function EVP_CIPHER_CTX_set_padding() this is used to
- disable standard block padding (aka PKCS#5 padding) in the EVP
- API, which was previously mandatory. This means that the data is
- not padded in any way and so the total length much be a multiple
- of the block size, otherwise an error occurs.
- [Steve Henson]
-
- +) Initial (incomplete) OCSP SSL support.
- [Steve Henson]
-
*) Fix CPU detection on Irix 6.x.
[Kurt Hockenbury <khockenb@stevens-tech.edu> and
"Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
- +) New function OCSP_parse_url(). This splits up a URL into its host,
- port and path components: primarily to parse OCSP URLs. New -url
- option to ocsp utility.
- [Steve Henson]
-
- +) New nonce behavior. The return value of OCSP_check_nonce() now
- reflects the various checks performed. Applications can decide
- whether to tolerate certain situations such as an absent nonce
- in a response when one was present in a request: the ocsp application
- just prints out a warning. New function OCSP_add1_basic_nonce()
- this is to allow responders to include a nonce in a response even if
- the request is nonce-less.
- [Steve Henson]
-
*) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
was empty.
+ [Steve Henson]
[This change does not apply to 0.9.7.]
*) Use the cached encoding of an X509_NAME structure rather than
but the code is actually correct.
[Steve Henson]
- +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
- skipped when using openssl x509 multiple times on a single input file,
- e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
- [Bodo Moeller]
-
- +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
- set string type: to handle setting ASN1_TIME structures. Fix ca
- utility to correctly initialize revocation date of CRLs.
- [Steve Henson]
-
- +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
- the clients preferred ciphersuites and rather use its own preferences.
- Should help to work around M$ SGC (Server Gated Cryptography) bug in
- Internet Explorer by ensuring unchanged hash method during stepup.
- [Lutz Jaenicke]
-
- +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
- to aes and add a new 'exist' option to print out symbols that don't
- appear to exist.
- [Steve Henson]
-
- +) Additional options to ocsp utility to allow flags to be set and
- additional certificates supplied.
- [Steve Henson]
-
- +) Add the option -VAfile to 'openssl ocsp', so the user can give the
- OCSP client a number of certificate to only verify the response
- signature against.
- [Richard Levitte]
-
*) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
Bleichenbacher's DSA attack.
Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
and leaves the highest bit random.
[Ulf Moeller, Bodo Moeller]
- +) Update Rijndael code to version 3.0 and change EVP AES ciphers to
- handle the new API. Currently only ECB, CBC modes supported. Add new
- AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
- for TLS" draft-ietf-tls-ciphersuite-03.txt.
- [Ben Laurie, Steve Henson]
-
*) In the NCONF_...-based implementations for CONF_... queries
(crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
a temporary CONF structure with the data component set to NULL
*) Fix potential buffer overrun for EBCDIC.
[Ulf Moeller]
- +) New function OCSP_copy_nonce() to copy nonce value (if present) from
- request to response.
- [Steve Henson]
-
- +) Functions for OCSP responders. OCSP_request_onereq_count(),
- OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
- extract information from a certificate request. OCSP_response_create()
- creates a response and optionally adds a basic response structure.
- OCSP_basic_add1_status() adds a complete single response to a basic
- reponse and returns the OCSP_SINGLERESP structure just added (to allow
- extensions to be included for example). OCSP_basic_add1_cert() adds a
- certificate to a basic response and OCSP_basic_sign() signs a basic
- response with various flags. New helper functions ASN1_TIME_check()
- (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
- (converts ASN1_TIME to GeneralizedTime).
- [Steve Henson]
-
- +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
- in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
- structure from a certificate. X509_pubkey_digest() digests tha public_key
- contents: this is used in various key identifiers.
- [Steve Henson]
-
*) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
keyUsage if basicConstraints absent for a CA.

headers.
[Richard Levitte]
- +) Make sk_sort() tolerate a NULL argument.
- [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
-
- +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
- passed by the function are trusted implicitly. If any of them signed the
- reponse then it is assumed to be valid and is not verified.
- [Steve Henson]
-
- -) Make the CRL encoding routines work with empty SEQUENCE OF. The

DH ciphersuites.
[Steve Henson]
- +) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
- to data. This was previously part of the PKCS7 ASN1 code. This
- was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
- [Steve Henson, reported by Kenneth R. Robinette
- <support@securenetterm.com>]
-
- +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
- routines: without these tracing memory leaks is very painful.
- Fix leaks in PKCS12 and PKCS7 routines.
- [Steve Henson]
-
*) Add some EVP_add_digest_alias registrations (as found in
OpenSSL_add_all_digests()) to SSL_library_init()
aka OpenSSL_add_ssl_algorithms(). This provides improved
*) ./config script fixes.
[Ulf Moeller, Richard Levitte]
- +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
- Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
- effectively meant GeneralizedTime would never be used. Now it
- is initialised to -1 but X509_time_adj() now has to check the value
- and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
- V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
- [Steve Henson, reported by Kenneth R. Robinette
- <support@securenetterm.com>]
-
- +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
- result in a zero length in the ASN1_INTEGER structure which was
- not consistent with the structure when d2i_ASN1_INTEGER() was used
- and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
- to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
- where it did not print out a minus for negative ASN1_INTEGER.
- [Steve Henson]
-
*) Fix 'openssl passwd -1'.
[Bodo Moeller]
- +) Add summary printout to ocsp utility. The various functions which
- convert status values to strings have been renamed to:
- OCSP_response_status_str(), OCSP_cert_status_str() and
- OCSP_crl_reason_str() and are no longer static. New options
- to verify nonce values and to disable verification. OCSP response
- printout format cleaned up.
- [Steve Henson]
-
- +) Add additional OCSP certificate checks. These are those specified
- in RFC2560. This consists of two separate checks: the CA of the
- certificate being checked must either be the OCSP signer certificate
- or the issuer of the OCSP signer certificate. In the latter case the
- OCSP signer certificate must contain the OCSP signing extended key
- usage. This check is performed by attempting to match the OCSP
- signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
- in the OCSP_CERTID structures of the response.
- [Steve Henson]
-
- +) Initial OCSP certificate verification added to OCSP_basic_verify()
- and related routines. This uses the standard OpenSSL certificate
- verify routines to perform initial checks (just CA validity) and
- to obtain the certificate chain. Then additional checks will be
- performed on the chain. Currently the root CA is checked to see
- if it is explicitly trusted for OCSP signing. This is used to set
- a root CA as a global signing root: that is any certificate that
- chains to that CA is an acceptable OCSP signing certificate.
- [Steve Henson]
-
- +) New '-extfile ...' option to 'openssl ca' for reading X.509v3
- extensions from a separate configuration file.
- As when reading extensions from the main configuration file,
- the '-extensions ...' option may be used for specifying the
- section to use.
- [Massimiliano Pala <madwolf@comune.modena.it>]
-
*) Change PKCS12_key_gen_asc() so it can cope with non null
terminated strings whose length is passed in the passlen
parameter, for example from PEM callbacks. This was done
by adding an extra length parameter to asc2uni().
[Steve Henson, reported by <oddissey@samsung.co.kr>]
- +) New OCSP utility. Allows OCSP requests to be generated or
- read. The request can be sent to a responder and the output
- parsed, outputed or printed in text form. Not complete yet:
- still needs to check the OCSP response validity.
- [Steve Henson]
-
- +) New subcommands for 'openssl ca':
- 'openssl ca -status <serial>' prints the status of the cert with
- the given serial number (according to the index file).
- 'openssl ca -updatedb' updates the expiry status of certificates
- in the index file.
- [Massimiliano Pala <madwolf@comune.modena.it>]
-
- +) New '-newreq-nodes' command option to CA.pl. This is like
- '-newreq', but calls 'openssl req' with the '-nodes' option
- so that the resulting key is not encrypted.
- [Damien Miller <djm@mindrot.org>]
-
- +) New configuration for the GNU Hurd.
- [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
-
- +) Initial code to implement OCSP basic response verify. This
- is currently incomplete. Currently just finds the signer's
- certificate and verifies the signature on the response.
- [Steve Henson]
-
- +) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
- value of OPENSSLDIR. This is available via the new '-d' option
- to 'openssl version', and is also included in 'openssl version -a'.
- [Bodo Moeller]
-
*) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
call failed, free the DSA structure.
[Bodo Moeller]
- +) Allowing defining memory allocation callbacks that will be given
- file name and line number information in additional arguments
- (a const char* and an int). The basic functionality remains, as
- well as the original possibility to just replace malloc(),
- realloc() and free() by functions that do not know about these
- additional arguments. To register and find out the current
- settings for extended allocation functions, the following
- functions are provided:
-
- CRYPTO_set_mem_ex_functions
- CRYPTO_set_locked_mem_ex_functions
- CRYPTO_get_mem_ex_functions
- CRYPTO_get_locked_mem_ex_functions
-
- These work the same way as CRYPTO_set_mem_functions and friends.
- CRYPTO_get_[locked_]mem_functions now writes 0 where such an
- extended allocation function is enabled.
- Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
- a conventional allocation function is enabled.
- [Richard Levitte, Bodo Moeller]
-
*) Fix to uni2asc() to cope with zero length Unicode strings.
These are present in some PKCS#12 files.
[Steve Henson]
- +) Finish off removing the remaining LHASH function pointer casts.
- There should no longer be any prototype-casting required when using
- the LHASH abstraction, and any casts that remain are "bugs". See
- the callback types and macros at the head of lhash.h for details
- (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
- [Geoff Thorpe]
-
- +) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
- If /dev/[u]random devices are not available or do not return enough
- entropy, EGD style sockets (served by EGD or PRNGD) will automatically
- be queried.
- The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
- /etc/entropy will be queried once each in this sequence, quering stops
- when enough entropy was collected without querying more sockets.
- [Lutz Jaenicke]
-
- +) Change the Unix RAND_poll() variant to be able to poll several
- random devices, as specified by DEVRANDOM, until a sufficient amount
- of data has been collected. We spend at most 10 ms on each file
- (select timeout) and read in non-blocking mode. DEVRANDOM now
- defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
- (previously it was just the string "/dev/urandom"), so on typical
- platforms the 10 ms delay will never occur.
- Also separate out the Unix variant to its own file, rand_unix.c.
- For VMS, there's a currently-empty rand_vms.c.
- [Richard Levitte]
-
- +) Move OCSP client related routines to ocsp_cl.c. These
- provide utility functions which an application needing
- to issue a request to an OCSP responder and analyse the
- response will typically need: as opposed to those which an
- OCSP responder itself would need which will be added later.
-
- OCSP_request_sign() signs an OCSP request with an API similar
- to PKCS7_sign(). OCSP_response_status() returns status of OCSP
- response. OCSP_response_get1_basic() extracts basic response
- from response. OCSP_resp_find_status(): finds and extracts status
- information from an OCSP_CERTID structure (which will be created
- when the request structure is built). These are built from lower
- level functions which work on OCSP_SINGLERESP structures but
- wont normally be used unless the application wishes to examine
- extensions in the OCSP response for example.
-
- Replace nonce routines with a pair of functions.
- OCSP_request_add1_nonce() adds a nonce value and optionally
- generates a random value. OCSP_check_nonce() checks the
- validity of the nonce in an OCSP response.
- [Steve Henson]
-
- +) Change function OCSP_request_add() to OCSP_request_add0_id().
- This doesn't copy the supplied OCSP_CERTID and avoids the
- need to free up the newly created id. Change return type
- to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
- This can then be used to add extensions to the request.
- Deleted OCSP_request_new(), since most of its functionality
- is now in OCSP_REQUEST_new() (and the case insensitive name
- clash) apart from the ability to set the request name which
- will be added elsewhere.
- [Steve Henson]
-
- +) Update OCSP API. Remove obsolete extensions argument from
- various functions. Extensions are now handled using the new
- OCSP extension code. New simple OCSP HTTP function which
- can be used to send requests and parse the response.
- [Steve Henson]
-
- +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
- ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
- uses the special reorder version of SET OF to sort the attributes
- and reorder them to match the encoded order. This resolves a long
- standing problem: a verify on a PKCS7 structure just after signing
- it used to fail because the attribute order did not match the
- encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
- it uses the received order. This is necessary to tolerate some broken
- software that does not order SET OF. This is handled by encoding
- as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
- to produce the required SET OF.
- [Steve Henson]
-
- +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
- OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
- files to get correct declarations of the ASN.1 item variables.
- [Richard Levitte]
-
- +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
- PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
- asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
- NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
- New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
- ASN1_ITEM and no wrapper functions.
- [Steve Henson]
-
- +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
- replace the old function pointer based I/O routines. Change most of
- the *_d2i_bio() and *_d2i_fp() functions to use these.
- [Steve Henson]
-
- +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
- lines, recognice more "algorithms" that can be deselected, and make
- it complain about algorithm deselection that isn't recognised.
- [Richard Levitte]
-
- +) New ASN1 functions to handle dup, sign, verify, digest, pack and
- unpack operations in terms of ASN1_ITEM. Modify existing wrappers
- to use new functions. Add NO_ASN1_OLD which can be set to remove
- some old style ASN1 functions: this can be used to determine if old
- code will still work when these eventually go away.
- [Steve Henson]
-
- +) New extension functions for OCSP structures, these follow the
- same conventions as certificates and CRLs.
- [Steve Henson]
-
- +) New function X509V3_add1_i2d(). This automatically encodes and
- adds an extension. Its behaviour can be customised with various
- flags to append, replace or delete. Various wrappers added for
- certifcates and CRLs.
- [Steve Henson]
-
- +) Fix to avoid calling the underlying ASN1 print routine when
- an extension cannot be parsed. Correct a typo in the
- OCSP_SERVICELOC extension. Tidy up print OCSP format.
- [Steve Henson]
-
*) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
when writing a 32767 byte record.
[Bodo Moeller, Geoff Thorpe; original patch submitted by
"Reddie, Steven" <Steven.Reddie@ca.com>]
- +) Make mkdef.pl parse some of the ASN1 macros and add apropriate
- entries for variables.
- [Steve Henson]
-
*) Fix a deadlock in CRYPTO_mem_leaks().
[Bodo Moeller]
- +) Add functionality to apps/openssl.c for detecting locking
- problems: As the program is single-threaded, all we have
- to do is register a locking callback using an array for
- storing which locks are currently held by the program.
- [Bodo Moeller]
-
- +) Use a lock around the call to CRYPTO_get_ex_new_index() in
- SSL_get_ex_data_X509_STORE_idx(), which is used in
- ssl_verify_cert_chain() and thus can be called at any time
- during TLS/SSL handshakes so that thread-safety is essential.
- Unfortunately, the ex_data design is not at all suited
- for multi-threaded use, so it probably should be abolished.
- [Bodo Moeller]
-
- +) Added Broadcom "ubsec" ENGINE to OpenSSL.
- [Broadcom, tweaked and integrated by Geoff Thorpe]
-
- +) Move common extension printing code to new function
- X509V3_print_extensions(). Reorganise OCSP print routines and
- implement some needed OCSP ASN1 functions. Add OCSP extensions.
- [Steve Henson]
-
- +) New function X509_signature_print() to remove duplication in some
- print routines.
- [Steve Henson]
-
- +) Add a special meaning when SET OF and SEQUENCE OF flags are both
- set (this was treated exactly the same as SET OF previously). This
- is used to reorder the STACK representing the structure to match the
- encoding. This will be used to get round a problem where a PKCS7
- structure which was signed could not be verified because the STACK
- order did not reflect the encoded order.
- [Steve Henson]
-
- +) Reimplement the OCSP ASN1 module using the new code.
- [Steve Henson]
-
- +) Update the X509V3 code to permit the use of an ASN1_ITEM structure
- for its ASN1 operations. The old style function pointers still exist
- for now but they will eventually go away.
- [Steve Henson]
-
- +) Merge in replacement ASN1 code from the ASN1 branch. This almost
- completely replaces the old ASN1 functionality with a table driven
- encoder and decoder which interprets an ASN1_ITEM structure describing
- the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
- largely maintained. Almost all of the old asn1_mac.h macro based ASN1
- has also been converted to the new form.
- [Steve Henson]
-
- +) Change BN_mod_exp_recp so that negative moduli are tolerated
- (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
- so that BN_mod_exp_mont and BN_mod_exp_mont_word work
- for negative moduli.
- [Bodo Moeller]
-
- +) Fix BN_uadd and BN_usub: Always return non-negative results instead
- of not touching the result's sign bit.
- [Bodo Moeller]
-
- +) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
- set.
- [Bodo Moeller]
-
- +) Changed the LHASH code to use prototypes for callbacks, and created
- macros to declare and implement thin (optionally static) functions
- that provide type-safety and avoid function pointer casting for the
- type-specific callbacks.
- [Geoff Thorpe]
-
*) Use better test patterns in bntest.
[Ulf Möller]
- +) Added Kerberos Cipher Suites to be used with TLS, as written in
- RFC 2712.
- [Veers Staats <staatsvr@asc.hpc.mil>,
- Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
-
*) rand_win.c fix for Borland C.
[Ulf Möller]
*) BN_rshift bugfix for n == 0.
[Bodo Moeller]

- in sections depending on the subject.
- [Richard Levitte]
-
- +) Have the zlib compression code load ZLIB.DLL dynamically under
- Windows.
- [Richard Levitte]
-
- +) New function BN_mod_sqrt for computing square roots modulo a prime
- (using the probabilistic Tonelli-Shanks algorithm unless
- p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
- be handled deterministically).
- [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]

[Lutz Jaenicke]
- +) Make BN_mod_inverse faster by explicitly handling small quotients
- in the Euclid loop. (Speed gain about 20% for small moduli [256 or

Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
does the actual work for ssl3_read_internal.
[Bodo Moeller]
- +) New function BN_kronecker.
- [Bodo Moeller]
-
- +) Fix BN_gcd so that it works on negative inputs; the result is
- positive unless both parameters are zero.
- Previously something reasonably close to an infinite loop was
- possible because numbers could be growing instead of shrinking
- in the implementation of Euclid's algorithm.
- [Bodo Moeller]
-
- +) Fix BN_is_word() and BN_is_one() macros to take into account the
- sign of the number in question.
-
- Fix BN_is_word(a,w) to work correctly for w == 0.
-
- The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
- because its test if the absolute value of 'a' equals 'w'.
- Note that BN_abs_is_word does *not* handle w == 0 reliably;
- it exists mostly for use in the implementations of BN_is_zero(),
- BN_is_one(), and BN_is_word().
- [Bodo Moeller]
-
*) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
the method-specific "init()" handler. Also clean up ex_data after
calling the method-specific "finish()" handler. Previously, this was
happening the other way round.
[Geoff Thorpe]
- +) New function BN_swap.
- [Bodo Moeller]
-
- +) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
- the exponentiation functions are more likely to produce reasonable
- results on negative inputs.
- [Bodo Moeller]
-
- +) Change BN_mod_mul so that the result is always non-negative.
- Previously, it could be negative if one of the factors was negative;
- I don't think anyone really wanted that behaviour.
- [Bodo Moeller]
-
- +) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
- (except for exponentiation, which stays in crypto/bn/bn_exp.c,
- and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
- and add new functions:
-
- BN_nnmod
- BN_mod_sqr
- BN_mod_add
- BN_mod_add_quick
- BN_mod_sub
- BN_mod_sub_quick
- BN_mod_lshift1
- BN_mod_lshift1_quick
- BN_mod_lshift
- BN_mod_lshift_quick
-
- These functions always generate non-negative results.
-
- BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
- such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
-
- BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
- BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
- be reduced modulo m.

- +) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
- was actually never needed) and in BN_mul(). The removal in BN_mul()
- required a small change in bn_mul_part_recursive() and the addition
- of the functions bn_cmp_part_words(), bn_sub_part_words() and
- bn_add_part_words(), which do the same thing as bn_cmp_words(),
- bn_sub_words() and bn_add_words() except they take arrays with
- differing sizes.
- [Richard Levitte]
-
- +) In 'openssl passwd', verify passwords read from the terminal
- unless the '-salt' option is used (which usually means that
- verification would just waste user's time since the resulting
- hash is going to be compared with some given password hash)
- or the new '-noverify' option is used.
-
- This is an incompatible change, but it does not affect
- non-interactive use of 'openssl passwd' (passwords on the command
- line, '-stdin' option, '-in ...' option) and thus should not
- cause any problems.
- [Bodo Moeller]
-
- +) Remove all references to RSAref, since there's no more need for it.
- [Richard Levitte]
-
*) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
The previous value, 12, was not always sufficient for BN_mod_exp().
[Bodo Moeller]
- +) Make DSO load along a path given through an environment variable
- (SHLIB_PATH) with shl_load().
- [Richard Levitte]
-
- +) Constify the ENGINE code as a result of BIGNUM constification.
- Also constify the RSA code and most things related to it. In a
- few places, most notable in the depth of the ASN.1 code, ugly
- casts back to non-const were required (to be solved at a later
- time)
- [Richard Levitte]
-
- +) Make it so the openssl application has all engines loaded by default.
- [Richard Levitte]
-
- +) Constify the BIGNUM routines a little more.
- [Richard Levitte]
-
*) Make sure that shared libraries get the internal name engine with
the full version number and not just 0. This should mark the
shared libraries as not backward compatible. Of course, this should
be changed again when we can guarantee backward binary compatibility.
[Richard Levitte]
- +) Add the following functions:
-
- ENGINE_load_cswift()
- ENGINE_load_chil()
- ENGINE_load_atalla()
- ENGINE_load_nuron()
- ENGINE_load_builtin_engines()
-
- That way, an application can itself choose if external engines that
- are built-in in OpenSSL shall ever be used or not. The benefit is
- that applications won't have to be linked with libdl or other dso
- libraries unless it's really needed.
-
- Changed 'openssl engine' to load all engines on demand.
- Changed the engine header files to avoid the duplication of some
- declarations (they differed!).
- [Richard Levitte]
-
- +) 'openssl engine' can now list capabilities.
- [Richard Levitte]
-
- +) Better error reporting in 'openssl engine'.
- [Richard Levitte]
-
- +) Never call load_dh_param(NULL) in s_server.
- [Bodo Moeller]
-
- +) Add engine application. It can currently list engines by name and
- identity, and test if they are actually available.
- [Richard Levitte]
-
- +) Add support for shared libraries under Irix.
- [Albert Chin-A-Young <china@thewrittenword.com>]
-
- +) Improve RPM specification file by forcing symbolic linking and making
- sure the installed documentation is also owned by root.root.
- [Damien Miller <djm@mindrot.org>]
-
- +) Add configuration option to build on Linux on both big-endian and
- little-endian MIPS.
- [Ralf Baechle <ralf@uni-koblenz.de>]
-
- +) Give the OpenSSL applications more possibilities to make use of
- keys (public as well as private) handled by engines.
- [Richard Levitte]
-
- +) Add OCSP code that comes from CertCo.
- [Richard Levitte]
-
- +) Add VMS support for the Rijndael code.
- [Richard Levitte]
-
- +) Added untested support for Nuron crypto accelerator.
- [Ben Laurie]
-
- +) Add support for external cryptographic devices. This code was
- previously distributed separately as the "engine" branch.
- [Geoff Thorpe, Richard Levitte]
-
- +) Rework the filename-translation in the DSO code. It is now possible to
- have far greater control over how a "name" is turned into a filename
- depending on the operating environment and any oddities about the
- different shared library filenames on each system.
- [Geoff Thorpe]
-
- +) Support threads on FreeBSD-elf in Configure.
- [Richard Levitte]
-
- +) Add the possibility to create shared libraries on HP-UX
- [Richard Levitte]
-
- +) Fix for SHA1 assembly problem with MASM: it produces
- warnings about corrupt line number information when assembling
- with debugging information. This is caused by the overlapping
- of two sections.
- [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
-
- +) NCONF changes.
- NCONF_get_number() has no error checking at all. As a replacement,
- NCONF_get_number_e() is defined (_e for "error checking") and is
- promoted strongly. The old NCONF_get_number is kept around for
- binary backward compatibility.
- Make it possible for methods to load from something other than a BIO,
- by providing a function pointer that is given a name instead of a BIO.
- For example, this could be used to load configuration data from an
- LDAP server.
- [Richard Levitte]
-
*) Fix typo in get_cert_by_subject() in by_dir.c
[Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
static ones.
[Richard Levitte]
- +) Fix for non blocking accept BIOs. Added new I/O special reason
- BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
- with non blocking I/O was not possible because no retry code was
- implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
- this case.
- [Steve Henson]
-
- +) Added the beginnings of Rijndael support.
- [Ben Laurie]
-
- +) Fix for bug in DirectoryString mask setting. Add support for
- X509_NAME_print_ex() in 'req' and X509_print_ex() function
- to allow certificate printing to more controllable, additional
- 'certopt' option to 'x509' to allow new printing options to be
- set.
- [Steve Henson]
-
- +) Clean old EAY MD5 hack from e_os.h.
- [Richard Levitte]
-
*) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
default is static libraries only, and the OpenSSL programs
are always statically linked for now, but there are
preparations for dynamic linking in place.
- This has been tested on Linux and True64.
+ This has been tested on Linux and Tru64.
