Paul Bakker6c0ceb32011-12-04 12:24:18 +0000544 * Added permissive certificate parsing to x509parse_crt() and
545 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +0100546 encountering a parse-error. Beware that the meaning of return values has
547 changed!

582 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100583 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000584 * Functions requiring File System functions can now be disabled

593 * Major argument / variable rewrite. Introduced use of size_t
594 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100595 better unsigned / signed use. Renamed internal bigint types
596 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000597 * mpi_init() and mpi_free() now only accept a single MPI
598 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000599 * The error codes have been remapped and combining error codes
600 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100601 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000602 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
603 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100604 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
605 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
606 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
607 after the handshake.

849XySSL ChangeLog
850
851= Version 0.9 released on 2008-03-16
852
853 * Added support for ciphersuite: SSL_RSA_AES_128_SHA
854 * Enabled support for large files by default in aescrypt2.c
855 * Preliminary openssl wrapper contributed by David Barrett
856 * Fixed a bug in ssl_write() that caused the same payload to
857 be sent twice in non-blocking mode when send returns EAGAIN
858 * Fixed ssl_parse_client_hello(): session id and challenge must
859 not be swapped in the SSLv2 ClientHello (found by Greg Robson)
860 * Added user-defined callback debug function (Krystian Kolodziej)
861 * Before freeing a certificate, properly zero out all cert. data
862 * Fixed the "mode" parameter so that encryption/decryption are
863 not swapped on PadLock; also fixed compilation on older versions
864 of gcc (bug reported by David Barrett)
865 * Correctly handle the case in padlock_xcryptcbc() when input or
866 ouput data is non-aligned by falling back to the software
867 implementation, as VIA Nehemiah cannot handle non-aligned buffers
868 * Fixed a memory leak in x509parse_crt() which was reported by Greg
869 Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to
870 Matthew Page who reported several bugs
871 * Fixed x509_get_ext() to accept some rare certificates which have
872 an INTEGER instead of a BOOLEAN for BasicConstraints::cA.
873 * Added support on the client side for the TLS "hostname" extension
874 (patch contributed by David Patino)
875 * Make x509parse_verify() return BADCERT_CN_MISMATCH when an empty
876 string is passed as the CN (bug reported by spoofy)
877 * Added an option to enable/disable the BN assembly code
878 * Updated rsa_check_privkey() to verify that (D*E) = 1 % (P-1)*(Q-1)
879 * Disabled obsolete hash functions by default (MD2, MD4); updated
880 selftest and benchmark to not test ciphers that have been disabled
881 * Updated x509parse_cert_info() to correctly display byte 0 of the
882 serial number, setup correct server port in the ssl client example
883 * Fixed a critical denial-of-service with X.509 cert. verification:
884 peer may cause xyssl to loop indefinitely by sending a certificate
885 for which the RSA signature check fails (bug reported by Benoit)
886 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
887 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
888 * Fixed HMAC-SHA-384 and HMAC-SHA-512 (thanks to Josh Sinykin)
889 * Modified ssl_parse_client_key_exchange() to protect against
890 Daniel Bleichenbacher attack on PKCS#1 v1.5 padding, as well
891 as the Klima-Pokorny-Rosa extension of Bleichenbacher's attack
892 * Updated rsa_gen_key() so that ctx->N is always nbits in size
893 * Fixed assembly PPC compilation errors on Mac OS X, thanks to
894 David Barrett and Dusan Semen

903 * Fixed net_recv(), thanks to Lorenz Schori and Egon Kocjan
904 * Added user-defined callbacks for handling I/O and sessions

909 * Added an SSL/TLS stress testing program (ssl_test.c)
