Paul Bakker6c0ceb32011-12-04 12:24:18 +0000724 * Added permissive certificate parsing to x509parse_crt() and
725 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +0100726 encountering a parse-error. Beware that the meaning of return values has
727 changed!

Paul Bakker1fe7d9b2011-11-15 15:26:03 +0000737 * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
738 smaller than the hash length. (Closes ticket #41)

761 * Added additional Cipher Block Modes to symmetric ciphers
762 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100763 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000764 * Functions requiring File System functions can now be disabled
765 by undefining POLARSSL_FS_IO

773 * Major argument / variable rewrite. Introduced use of size_t
774 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100775 better unsigned / signed use. Renamed internal bigint types
776 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000777 * mpi_init() and mpi_free() now only accept a single MPI
778 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000779 * The error codes have been remapped and combining error codes
780 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100781 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000782 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
783 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100784 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
785 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
786 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
787 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000788 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

803 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000804 * x509parse_key() (and as a consequence x509parse_keyfile())
805 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100806 before parsing a key or keyfile!

Paul Bakkera35aa542013-03-06 17:06:21 +0100873 ciphersuite respectively. This clarifies the difference
874 with the generic cipher layer and is better naming
875 altogether
