OpenSSL CHANGES
_______________
- Changes between 0.9.4 and 0.9.5 [xx XXX 2000]
+ Changes between 0.9.5a and 0.9.6 [xx XXX 2000]
+
+ *) Initial DSO code added into libcrypto for letting OpenSSL (and
+ OpenSSL-based applications) load shared libraries and bind to
+ them in a portable way.
+ [Geoff Thorpe, with contributions from Richard Levitte]
+
+ Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
+
+ *) Make sure _lrotl and _lrotr are only used with MSVC.
+
+ *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
+ (the default implementation of RAND_status).
+
+ *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
+ to '-clrext' (= clear extensions), as intended and documented.
+ [Bodo Moeller; inconsistency pointed out by Michael Attili
+ <attili@amaxo.com>]
+
+ *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
+ was larger than the MD block size.
+ [Steve Henson, pointed out by Yost William <YostW@tce.com>]
+
+ *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
+ fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
+ using the passed key: if the passed key was a private key the result
+ of X509_print(), for example, would be to print out all the private key
+ components.
+ [Steve Henson]
+
+ *) des_quad_cksum() byte order bug fix.
+ [Ulf Möller, using the problem description in krb4-0.9.7, where
+ the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
+
+ *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
+ discouraged.
+ [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
+
+ *) For easily testing in shell scripts whether some command
+ 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
+ returns with exit code 0 iff no command of the given name is available.
+ 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
+ the output goes to stdout and nothing is printed to stderr.
+ Additional arguments are always ignored.
+
+ Since for each cipher there is a command of the same name,
+ the 'no-cipher' compilation switches can be tested this way.
+
+ ('openssl no-XXX' is not able to detect pseudo-commands such
+ as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
+ [Bodo Moeller]
+
+ *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
+ [Bodo Moeller]
+
+ *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
+ is set; it will be thrown away anyway because each handshake creates
+ its own key.
+ ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
+ to parameters -- in previous versions (since OpenSSL 0.9.3) the
+ 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
+ you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
+ [Bodo Moeller]
+
+ *) New s_client option -ign_eof: EOF at stdin is ignored, and
+ 'Q' and 'R' lose their special meanings (quit/renegotiate).
+ This is part of what -quiet does; unlike -quiet, -ign_eof
+ does not suppress any output.
+ [Richard Levitte]
+
+ *) Add compatibility options to the purpose and trust code. The
+ purpose X509_PURPOSE_ANY is "any purpose" which automatically
+ accepts a certificate or CA, this was the previous behaviour,
+ with all the associated security issues.
+
+ X509_TRUST_COMPAT is the old trust behaviour: only and
+ automatically trust self signed roots in certificate store. A
+ new trust setting X509_TRUST_DEFAULT is used to specify that
+ a purpose has no associated trust setting and it should instead
+ use the value in the default purpose.
+ [Steve Henson]
+
+ *) Fix the PKCS#8 DSA private key code so it decodes keys again
+ and fix a memory leak.
+ [Steve Henson]
+
+ *) In util/mkerr.pl (which implements 'make errors'), preserve
+ reason strings from the previous version of the .c file, as
+ the default to have only downcase letters (and digits) in
+ automatically generated reasons codes is not always appropriate.
+ [Bodo Moeller]
+
+ *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
+ using strerror. Previously, ERR_reason_error_string() returned
+ library names as reason strings for SYSerr; but SYSerr is a special
+ case where small numbers are errno values, not library numbers.
+ [Bodo Moeller]
+
+ *) Add '-dsaparam' option to 'openssl dhparam' application. This
+ converts DSA parameters into DH parameters. (When creating parameters,
+ DSA_generate_parameters is used.)
+ [Bodo Moeller]
+
+ *) Include 'length' (recommended exponent length) in C code generated
+ by 'openssl dhparam -C'.
+ [Bodo Moeller]
+
+ *) The second argument to set_label in perlasm was already being used
+ so couldn't be used as a "file scope" flag. Moved to third argument
+ which was free.
+ [Steve Henson]
+
+ *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
+ instead of RAND_bytes for encryption IVs and salts.
+ [Bodo Moeller]
+
+ *) Include RAND_status() into RAND_METHOD instead of implementing
+ it only for md_rand.c Otherwise replacing the PRNG by calling
+ RAND_set_rand_method would be impossible.
+ [Bodo Moeller]
+
+ *) Don't let DSA_generate_key() enter an infinite loop if the random
+ number generation fails.
+ [Bodo Moeller]
+
+ *) New 'rand' application for creating pseudo-random output.
+ [Bodo Moeller]
+
+ *) Added configuration support for Linux/IA64
+ [Rolf Haberrecker <rolf@suse.de>]
+
+ *) Assembler module support for Mingw32.
+ [Ulf Möller]
+
+ *) Shared library support for HPUX (in shlib/).
+ [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
+
+ *) Shared library support for Solaris gcc.
+ [Lutz Behnke <behnke@trustcenter.de>]
+
+ Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
+
+ *) PKCS7_encrypt() was adding text MIME headers twice because they
+ were added manually and by SMIME_crlf_copy().
+ [Steve Henson]
+
+ *) In bntest.c don't call BN_rand with zero bits argument.
+ [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
+
+ *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
+ case was implemented. This caused BN_div_recp() to fail occasionally.
+ [Ulf Möller]
+
+ *) Add an optional second argument to the set_label() in the perl
+ assembly language builder. If this argument exists and is set
+ to 1 it signals that the assembler should use a symbol whose
+ scope is the entire file, not just the current function. This
+ is needed with MASM which uses the format label:: for this scope.
+ [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
+
+ *) Change the ASN1 types so they are typedefs by default. Before
+ almost all types were #define'd to ASN1_STRING which was causing
+ STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
+ for example.
+ [Steve Henson]
+
+ *) Change names of new functions to the new get1/get0 naming
+ convention: After 'get1', the caller owns a reference count
+ and has to call ..._free; 'get0' returns a pointer to some
+ data structure without incrementing reference counters.
+ (Some of the existing 'get' functions increment a reference
+ counter, some don't.)
+ Similarly, 'set1' and 'add1' functions increase reference
+ counters or duplicate objects.
+ [Steve Henson]
+
+ *) Allow for the possibility of temp RSA key generation failure:
+ the code used to assume it always worked and crashed on failure.
+ [Steve Henson]
+
+ *) Fix potential buffer overrun problem in BIO_printf().
+ [Ulf Möller, using public domain code by Patrick Powell; problem
+ pointed out by David Sacerdote <das33@cornell.edu>]
+
+ *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
+ RAND_egd() and RAND_status(). In the command line application,
+ the EGD socket can be specified like a seed file using RANDFILE
+ or -rand.
+ [Ulf Möller]
*) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
Some CAs (e.g. Verisign) distribute certificates in this form.
many platforms, but is not correct. As these functions are usually
called by macros defined in OpenSSL header files, most source code
should work without changes.
+ [Richard Levitte]
*) <openssl/opensslconf.h> (which is created by Configure) now contains
sections with information on -D... compiler switches used for
#define OPENSSL_ALGORITHM_DEFINES
#include <openssl/opensslconf.h>
defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
+ [Richard Levitte, Ulf and Bodo Möller]
*) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
record layer.
*) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
[Bodo Moeller]
- *) New function X509_CTX_rget_chain(), this returns the chain
+ *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
+ in the 0.9.5 release), this returns the chain
from an X509_CTX structure with a dup of the stack and all
the X509 reference counts upped: so the stack will exist
after X509_CTX_cleanup() has been called. Modify pkcs12.c
it clearly returns an error if you try to read the wrong kind of key.
Added a -pubkey option to the 'x509' utility to output the public key.
- Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() and add
- EVP_PKEY_rset_*() functions that do the same as the EVP_PKEY_assign_*()
- except they up the reference count of the added key (they don't "swallow"
- the supplied key).
+ Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
+ (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
+ EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
+ that do the same as the EVP_PKEY_assign_*() except they up the
+ reference count of the added key (they don't "swallow" the
+ supplied key).
[Steve Henson]
*) Fixes to crypto/x509/by_file.c the code to read in certificates and
