OpenSSL CHANGES
_______________
-
Changes between 0.9.3a and 0.9.4
+ *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
+ Also really enable memory leak checks in openssl.c and in some
+ test programs.
+ [Chad C. Mulligan, Bodo Moeller]
+
+ *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
+ up the length of negative integers. This has now been simplified to just
+ store the length when it is first determined and use it later, rather
+ than trying to keep track of where data is copied and updating it to
+ point to the end.
+ [Steve Henson, reported by Brien Wheeler
+ <bwheeler@authentica-security.com>]
+
+ *) Add a new function PKCS7_signatureVerify. This allows the verification
+ of a PKCS#7 signature but with the signing certificate passed to the
+ function itself. This contrasts with PKCS7_dataVerify which assumes the
+ certificate is present in the PKCS#7 structure. This isn't always the
+ case: certificates can be omitted from a PKCS#7 structure and be
+ distributed by "out of band" means (such as a certificate database).
+ [Steve Henson]
+
+ *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
+ function prototypes in pem.h, also change util/mkdef.pl to add the
+ necessary function names.
+ [Steve Henson]
+
+ *) mk1mf.pl (used by Windows builds) did not properly read the
+ options set by Configure in the top level Makefile; typo fixed,
+ now "no-idea" etc. works as intended.
+ [Bodo Moeller]
+
+ *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
+ file to be loaded from a BIO or FILE pointer. The BIO version will
+ for example allow memory BIOs to contain config info.
+ [Steve Henson]
+
+ *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
+ Whoever hopes to achieve shared-library compatibility across versions
+ must use this, not the compile-time macro.
+ (Exercise 0.9.4: Which is the minimum library version required by
+ such programs?)
+ Note: All this applies only to multi-threaded programs, others don't
+ need locks.
+ [Bodo Moeller]
+
+ *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
+ through a BIO pair triggered the default case, i.e.
+ SSLerr(...,SSL_R_UNKNOWN_STATE).
+ [Bodo Moeller]
+
+ *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
+ can use the SSL library even if none of the specific BIOs is
+ appropriate.
+ [Bodo Moeller]
+
+ *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
+ for the encoded length.
+ [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
+
+ *) Add initial documentation of the X509V3 functions.
+ [Steve Henson]
+
+ *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
+ PEM_write_bio_PKCS8PrivateKey() that are equivalent to
+ PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
+ secure PKCS#8 private key format with a high iteration count.
+ [Steve Henson]
+
+ *) Fix determination of Perl interpreter: A perl or perl5
+ _directory_ in $PATH was also accepted as the interpreter.
+ [Ralf S. Engelschall]
+
+ *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
+ wrong with it but it was very old and did things like calling
+ PEM_ASN1_read() directly and used MD5 for the hash not to mention some
+ unusual formatting.
+ [Steve Henson]
+
+ *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
+ to use the new extension code.
+ [Steve Henson]
+
+ *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
+ with macros. This should make it easier to change their form, add extra
+ arguments etc. Fix a few PEM prototypes which didn't have cipher as a
+ constant.
+ [Steve Henson]
+
+ *) Add to configuration table a new entry that can specify an alternative
+ name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
+ according to Mark Crispin <MRC@Panda.COM>.
+ [Bodo Moeller]
+
+#if 0
+ *) DES CBC did not update the IV. Weird.
+ [Ben Laurie]
+#else
+ des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
+ Changing the behaviour of the former might break existing programs --
+ where IV updating is needed, des_ncbc_encrypt can be used.
+#endif
+
+ *) When bntest is run from "make test" it drives bc to check its
+ calculations, as well as internally checking them. If an internal check
+ fails, it needs to cause bc to give a non-zero result or make test carries
+ on without noticing the failure. Fixed.
+ [Ben Laurie]
+
+ *) DES library cleanups.
+ [Ulf Möller]
+
+ *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
+ used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
+ ciphers. NOTE: although the key derivation function has been verified
+ against some published test vectors it has not been extensively tested
+ yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
+ of v2.0.
+ [Steve Henson]
+
+ *) Instead of "mkdir -p", which is not fully portable, use new
+ Perl script "util/mkdir-p.pl".
+ [Bodo Moeller]
+
+ *) Rewrite the way password based encryption (PBE) is handled. It used to
+ assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
+ structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
+ but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
+ the 'parameter' field of the AlgorithmIdentifier is passed to the
+ underlying key generation function so it must do its own ASN1 parsing.
+ This has also changed the EVP_PBE_CipherInit() function which now has a
+ 'parameter' argument instead of literal salt and iteration count values
+ and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
+ [Steve Henson]
+
*) Support for PKCS#5 v1.5 compatible password based encryption algorithms
and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
support mutable.
[Ben Laurie]
- *) "linux-sparc64-gcc" configuration (ultrapenguin).
+ *) "linux-sparc64" configuration (ultrapenguin).
[Ray Miller <ray.miller@oucs.ox.ac.uk>]
+ "linux-sparc" configuration.
+ [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
*) config now generates no-xxx options for missing ciphers.
