525 SSL contexts without needing to set all non-connection-specific
526 data and pointers again. Adapted ssl_server to use this functionality.
Paul Bakker490ecc82011-10-06 13:04:09 +0000527 * Added ssl_set_max_version() to allow clients to offer a lower maximum
528 supported version to a server to help buggy server implementations.

535 entropy sources
Paul Bakker7eb013f2011-10-06 12:37:39 +0000536
Paul Bakkerca6f3e22011-10-06 13:11:08 +0000537Changes

545 So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C.
Paul Bakker5e18aed2011-11-15 15:38:45 +0000546 * Changed the defined key-length of DES ciphers in cipher.h to include the
547 parity bits, to prevent mistakes in copying data. (Closes ticket #33)

Paul Bakker6c0ceb32011-12-04 12:24:18 +0000558 * Added permissive certificate parsing to x509parse_crt() and
559 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +0100560 encountering a parse-error. Beware that the meaning of return values has
561 changed!
Paul Bakker69e095c2011-12-10 21:55:01 +0000562 * All error codes are now negative. Even on mermory failures and IO errors.

595 * Added additional Cipher Block Modes to symmetric ciphers
596 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100597 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000598 * Functions requiring File System functions can now be disabled
599 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +0000600 * A error_strerror function() has been added to translate between
601 error codes and their description.

607 * Major argument / variable rewrite. Introduced use of size_t
608 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100609 better unsigned / signed use. Renamed internal bigint types
610 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000611 * mpi_init() and mpi_free() now only accept a single MPI
612 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000613 * The error codes have been remapped and combining error codes
614 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100615 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000616 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
617 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100618 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
619 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
620 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
621 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000622 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

637 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000638 * x509parse_key() (and as a consequence x509parse_keyfile())
639 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100640 before parsing a key or keyfile!

878 of gcc (bug reported by David Barrett)
879 * Correctly handle the case in padlock_xcryptcbc() when input or
880 ouput data is non-aligned by falling back to the software
881 implementation, as VIA Nehemiah cannot handle non-aligned buffers

898 peer may cause xyssl to loop indefinitely by sending a certificate
899 for which the RSA signature check fails (bug reported by Benoit)
