OpenSSL CHANGES
_______________
- Changes between 0.9.7c and 0.9.8 [xx XXX xxxx]
+ Changes between 0.9.7e and 0.9.8 [xx XXX xxxx]
+
+ *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
+ exponent rather than 'unsigned long'. There is a corresponding change to
+ the new 'rsa_keygen' element of the RSA_METHOD structure.
+ [Jelte Jansen, Geoff Thorpe]
+
+ *) Functionality for creating the initial serial number file is now
+ moved from CA.pl to the 'ca' utility with a new option -create_serial.
+
+ (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
+ number file to 1, which is bound to cause problems. To avoid
+ the problems while respecting compatibility between different 0.9.7
+ patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in
+ CA.pl for serial number initialization. With the new release 0.9.8,
+ we can fix the problem directly in the 'ca' utility.)
+ [Steve Henson]
+
+ *) Reduced header interdepencies by declaring more opaque objects in
+ ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
+ give fewer recursive includes, which could break lazy source code - so
+ this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
+ developers should define this symbol when building and using openssl to
+ ensure they track the recommended behaviour, interfaces, [etc], but
+ backwards-compatible behaviour prevails when this isn't defined.
+ [Geoff Thorpe]
+
+ *) New function X509_POLICY_NODE_print() which prints out policy nodes.
+ [Steve Henson]
+
+ *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
+ This will generate a random key of the appropriate length based on the
+ cipher context. The EVP_CIPHER can provide its own random key generation
+ routine to support keys of a specific form. This is used in the des and
+ 3des routines to generate a key of the correct parity. Update S/MIME
+ code to use new functions and hence generate correct parity DES keys.
+ Add EVP_CHECK_DES_KEY #define to return an error if the key is not
+ valid (weak or incorrect parity).
+ [Steve Henson]
*) Add a local set of CRLs that can be used by X509_verify_cert() as well
as looking them up. This is useful when the verified structure may contain
*) Support for policyMappings certificate extension.
[Steve Henson]
- *) Fixed a typo bug that would cause ENGINE_set_default() to set an
- ENGINE as defaults for all supported algorithms irrespective of
- the 'flags' parameter. 'flags' is now honoured, so applications
- should make sure they are passing it correctly.
- [Geoff Thorpe]
-
*) Make sure the default DSA_METHOD implementation only uses its
dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
and change its own handlers to be NULL so as to remove unnecessary
differing sizes.
[Richard Levitte]
- Changes between 0.9.7c and 0.9.7d [xx XXX XXXX]
+ Changes between 0.9.7d and 0.9.7e [XX xxx XXXX]
+
+ *) Reduce the chances of duplicate issuer name and serial numbers (in
+ violation of RFC3280) using the OpenSSL certificate creation utilities.
+ This is done by creating a random 64 bit value for the initial serial
+ number when a serial number file is created or when a self signed
+ certificate is created using 'openssl req -x509'. The initial serial
+ number file is created using 'openssl x509 -next_serial' in CA.pl
+ rather than being initialized to 1.
+ [Steve Henson]
+
+ Changes between 0.9.7c and 0.9.7d [17 Mar 2004]
+
+ *) Fix null-pointer assignment in do_change_cipher_spec() revealed
+ by using the Codenomicon TLS Test Tool (CAN-2004-0079)
+ [Joe Orton, Steve Henson]
+
+ *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
+ (CAN-2004-0112)
+ [Joe Orton, Steve Henson]
+
+ *) Make it possible to have multiple active certificates with the same
+ subject in the CA index file. This is done only if the keyword
+ 'unique_subject' is set to 'no' in the main CA section (default
+ if 'CA_default') of the configuration file. The value is saved
+ with the database itself in a separate index attribute file,
+ named like the index file with '.attr' appended to the name.
+ [Richard Levitte]
*) X509 verify fixes. Disable broken certificate workarounds when
X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if
between threads, blinding will still be very fast).
[Bodo Moeller]
-yet to be integrated into this CVS branch:
-- Geoff's ENGINE_set_default() fix
+ *) Fixed a typo bug that would cause ENGINE_set_default() to set an
+ ENGINE as defaults for all supported algorithms irrespective of
+ the 'flags' parameter. 'flags' is now honoured, so applications
+ should make sure they are passing it correctly.
+ [Geoff Thorpe]
*) Target "mingw" now allows native Windows code to be generated in
the Cygwin environment as well as with the MinGW compiler.
*) Clean old EAY MD5 hack from e_os.h.

- Changes between 0.9.6j and 0.9.6k [30 Sep 2003]
+ Changes between 0.9.6l and 0.9.6m [17 Mar 2004]
- *) Fix various bugs revealed by running the NISCC test suite:
+ *) Fix null-pointer assignment in do_change_cipher_spec() revealed
+ by using the Codenomicon TLS Test Tool (CAN-2004-0079)
+ [Joe Orton, Steve Henson]
- Stop out of bounds reads in the ASN1 code when presented with
- invalid tags (CAN-2003-0543 and CAN-2003-0544).
-
- If verify callback ignores invalid public key errors don't try to check
- certificate signature with the NULL public key.
+ Changes between 0.9.6k and 0.9.6l [04 Nov 2003]
+
+ *) Fix additional bug revealed by the NISCC test suite:
+ Stop bug triggering large recursion when presented with
+ certain ASN.1 tags (CAN-2003-0851)
