Paul Bakkerb6ecaf52011-04-19 14:29:23 +00003= Version trunk
4Features
5 * Added additional Cipher Block Modes to symmetric ciphers
6 (AES CTR, Camellia CTR, XTEA CBC) including the option to
7 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +00008 * Functions requiring File System functions can now be disabled
9 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +000010 * A error_strerror function() has been added to translate between
11 error codes and their description.
Paul Bakkerb6ecaf52011-04-19 14:29:23 +000012
Paul Bakker23986e52011-04-24 08:57:21 +000013Changes
14 * Major argument / variable rewrite. Introduced use of size_t
15 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +000016 better unsigned / signed use. Renamed internal bigint types
17 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +000018 * mpi_init() and mpi_free() now only accept a single MPI
19 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +000020 * The error codes have been remapped and combining error codes
21 is now done with a PLUS instead of an OR as error codes
22 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +000023 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
24 net_recv() now returns 0 on EOF instead of
25 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
26 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
27 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
28 after the handshake.
29 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
30 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
31 POLARSSL_ERR_NET_TRY_AGAIN

40 with random data (Fixed ticket #10)

44 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +000045 * x509parse_key() (and as a consequence x509parse_keyfile())
46 does not zeroize memory in advance anymore. Use rsa_init()
47 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +000048
