404 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100405 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000406 * Functions requiring File System functions can now be disabled
407 by undefining POLARSSL_FS_IO

415 * Major argument / variable rewrite. Introduced use of size_t
416 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100417 better unsigned / signed use. Renamed internal bigint types
418 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000419 * mpi_init() and mpi_free() now only accept a single MPI
420 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000421 * The error codes have been remapped and combining error codes
422 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100423 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000424 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
425 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100426 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
427 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
428 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
429 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000430 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

445 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000446 * x509parse_key() (and as a consequence x509parse_keyfile())
447 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100448 before parsing a key or keyfile!
