Paul Bakker6c0ceb32011-12-04 12:24:18 +0000357 * Added permissive certificate parsing to x509parse_crt() and
358 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +0100359 encountering a parse-error. Beware that the meaning of return values has
360 changed!

395 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100396 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000397 * Functions requiring File System functions can now be disabled
398 by undefining POLARSSL_FS_IO

406 * Major argument / variable rewrite. Introduced use of size_t
407 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100408 better unsigned / signed use. Renamed internal bigint types
409 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000410 * mpi_init() and mpi_free() now only accept a single MPI
411 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000412 * The error codes have been remapped and combining error codes
413 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100414 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000415 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
416 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100417 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
418 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
419 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
420 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000421 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

436 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000437 * x509parse_key() (and as a consequence x509parse_keyfile())
438 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100439 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +0000440

Paul Bakkere3166ce2011-01-27 17:40:50 +0000504 * The ciphers member of ssl_context and the cipher member
505 of ssl_session have been renamed to ciphersuites and
Paul Bakkera35aa542013-03-06 17:06:21 +0100506 ciphersuite respectively. This clarifies the difference
507 with the generic cipher layer and is better naming
508 altogether
