+ *) 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.

+
+ Changes between 0.9.7b and 0.9.7c [xx XXX 2003]
+
+ *) New -ignore_err option in ocsp application to stop the server
+ exiting on the first error in a request.
+ [Steve Henson]
+
+ *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
+ extra data after the compression methods not only for TLS 1.0
+ but also for SSL 3.0 (as required by the specification).
+ [Bodo Moeller; problem pointed out by Matthias Loepfe]
+
+ *) Change X509_certificate_type() to mark the key as exported/exportable
+ when it's 512 *bits* long, not 512 bytes.
+ [Richard Levitte]
+
+ *) Change AES_cbc_encrypt() so it outputs exact multiple of
+ blocks during encryption.
+ [Richard Levitte]
+
+ *) Various fixes to base64 BIO and non blocking I/O. On write
+ flushes were not handled properly if the BIO retried. On read
+ data was not being buffered properly and had various logic bugs.
+ This also affects blocking I/O when the data being decoded is a
+ certain size.
+ [Steve Henson]
+
+ *) Various S/MIME bugfixes and compatibility changes:
+ output correct application/pkcs7 MIME type if
+ PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures.
+ Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening
+ of files as .eml work). Correctly handle very long lines in MIME
+ parser.
+ [Steve Henson]
+
+ Changes between 0.9.7a and 0.9.7b [10 Apr 2003]
+
+ *) Countermeasure against the Klima-Pokorny-Rosa extension of
+ Bleichbacher's attack on PKCS #1 v1.5 padding: treat
+ a protocol version number mismatch like a decryption error
+ in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
+ [Bodo Moeller]
+
+ *) Turn on RSA blinding by default in the default implementation
+ to avoid a timing attack. Applications that don't want it can call
+ RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
+ They would be ill-advised to do so in most cases.
+ [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
+
+ *) Change RSA blinding code so that it works when the PRNG is not
+ seeded (in this case, the secret RSA exponent is abused as
+ an unpredictable seed -- if it is not unpredictable, there
+ is no point in blinding anyway). Make RSA blinding thread-safe
+ by remembering the creator's thread ID in rsa->blinding and
+ having all other threads use local one-time blinding factors
+ (this requires more computation than sharing rsa->blinding, but
+ avoids excessive locking; and if an RSA object is not shared
+ between threads, blinding will still be very fast).
+ [Bodo Moeller]
+
+yet to be integrated into this CVS branch:
+- Geoff's ENGINE_set_default() fix
+
+ *) Target "mingw" now allows native Windows code to be generated in
+ the Cygwin environment as well as with the MinGW compiler.
+ [Ulf Moeller]
+
+ Changes between 0.9.7 and 0.9.7a [19 Feb 2003]
+
+ *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
+ via timing by performing a MAC computation even if incorrrect
+ block cipher padding has been found. This is a countermeasure
+ against active attacks where the attacker has to distinguish
+ between bad padding and a MAC verification error. (CAN-2003-0078)
+
+ [Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
+ Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
+ Martin Vuagnoux (EPFL, Ilion)]
+
+ *) Make the no-err option work as intended. The intention with no-err
+ is not to have the whole error stack handling routines removed from
+ libcrypto, it's only intended to remove all the function name and
+ reason texts, thereby removing some of the footprint that may not
+ be interesting if those errors aren't displayed anyway.
+
+ NOTE: it's still possible for any application or module to have it's
+ own set of error texts inserted. The routines are there, just not
+ used by default when no-err is given.
+ [Richard Levitte]
+
+ *) Add support for FreeBSD on IA64.
+ [dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454]
+
+ *) Adjust DES_cbc_cksum() so it returns the same value as the MIT
+ Kerberos function mit_des_cbc_cksum(). Before this change,
+ the value returned by DES_cbc_cksum() was like the one from
+ mit_des_cbc_cksum(), except the bytes were swapped.
+ [Kevin Greaney <Kevin.Greaney@hp.com> and Richard Levitte]
+
+ *) Allow an application to disable the automatic SSL chain building.
+ Before this a rather primitive chain build was always performed in
+ ssl3_output_cert_chain(): an application had no way to send the
+ correct chain if the automatic operation produced an incorrect result.
+
+ Now the chain builder is disabled if either:
+
+ 1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
+
+ 2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
+
+ The reasoning behind this is that an application would not want the
+ auto chain building to take place if extra chain certificates are
+ present and it might also want a means of sending no additional
+ certificates (for example the chain has two certificates and the
+ root is omitted).
+ [Steve Henson]
+
+ *) Add the possibility to build without the ENGINE framework.
+ [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
+
+ *) Under Win32 gmtime() can return NULL: check return value in
+ OPENSSL_gmtime(). Add error code for case where gmtime() fails.
+ [Steve Henson]
+
+ *) DSA routines: under certain error conditions uninitialized BN objects
+ could be freed. Solution: make sure initialization is performed early
+ enough. (Reported and fix supplied by Ivan D Nestlerode <nestler@MIT.EDU>,
+ Nils Larsch <nla@trustcenter.de> via PR#459)
+ [Lutz Jaenicke]
+
+ *) Another fix for SSLv2 session ID handling: the session ID was incorrectly
+ checked on reconnect on the client side, therefore session resumption
+ could still fail with a "ssl session id is different" error. This
+ behaviour is masked when SSL_OP_ALL is used due to
+ SSL_OP_MICROSOFT_SESS_ID_BUG being set.
+ Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
+ followup to PR #377.
+ [Lutz Jaenicke]
+
+ *) IA-32 assembler support enhancements: unified ELF targets, support
+ for SCO/Caldera platforms, fix for Cygwin shared build.
+ [Andy Polyakov]
+
+ *) Add support for FreeBSD on sparc64. As a consequence, support for
+ FreeBSD on non-x86 processors is separate from x86 processors on
+ the config script, much like the NetBSD support.
+ [Richard Levitte & Kris Kennaway <kris@obsecurity.org>]
+
+ Changes between 0.9.6h and 0.9.7 [31 Dec 2002]
+
+ [NB: OpenSSL 0.9.6i and later 0.9.6 patch levels were released after
+ OpenSSL 0.9.7.]
+
+ *) Fix session ID handling in SSLv2 client code: the SERVER FINISHED
+ code (06) was taken as the first octet of the session ID and the last
+ octet was ignored consequently. As a result SSLv2 client side session
+ caching could not have worked due to the session ID mismatch between
+ client and server.
+ Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
+ PR #377.
+ [Lutz Jaenicke]
+
+ *) Change the declaration of needed Kerberos libraries to use EX_LIBS
+ instead of the special (and badly supported) LIBKRB5. LIBKRB5 is
+ removed entirely.
+ [Richard Levitte]
+
+ *) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it
+ seems that in spite of existing for more than a year, many application
+ author have done nothing to provide the necessary callbacks, which
+ means that this particular engine will not work properly anywhere.
+ This is a very unfortunate situation which forces us, in the name
+ of usability, to give the hw_ncipher.c a static lock, which is part
+ of libcrypto.
+ NOTE: This is for the 0.9.7 series ONLY. This hack will never
+ appear in 0.9.8 or later. We EXPECT application authors to have
+ dealt properly with this when 0.9.8 is released (unless we actually
+ make such changes in the libcrypto locking code that changes will
+ have to be made anyway).
+ [Richard Levitte]
+
+ *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content
+ octets have been read, EOF or an error occurs. Without this change
+ some truncated ASN1 structures will not produce an error.
+ [Steve Henson]
+
+ *) Disable Heimdal support, since it hasn't been fully implemented.
+ Still give the possibility to force the use of Heimdal, but with
+ warnings and a request that patches get sent to openssl-dev.
+ [Richard Levitte]
