Paul Bakker6c0ceb32011-12-04 12:24:18 +0000572 * Added permissive certificate parsing to x509parse_crt() and
573 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +0100574 encountering a parse-error. Beware that the meaning of return values has
575 changed!

610 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100611 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000612 * Functions requiring File System functions can now be disabled
613 by undefining POLARSSL_FS_IO

621 * Major argument / variable rewrite. Introduced use of size_t
622 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100623 better unsigned / signed use. Renamed internal bigint types
624 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000625 * mpi_init() and mpi_free() now only accept a single MPI
626 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000627 * The error codes have been remapped and combining error codes
628 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100629 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000630 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
631 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100632 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
633 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
634 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
635 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000636 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

Paul Bakker98675492011-03-26 13:17:12 +0000652 * x509parse_key() (and as a consequence x509parse_keyfile())
653 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100654 before parsing a key or keyfile!
