1009 entropy sources
Paul Bakker7eb013f2011-10-06 12:37:39 +00001010
Paul Bakkerca6f3e22011-10-06 13:11:08 +00001011Changes

1033 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +01001034 encountering a parse-error. Beware that the meaning of return values has
1035 changed!
Paul Bakker69e095c2011-12-10 21:55:01 +00001036 * All error codes are now negative. Even on mermory failures and IO errors.

1070 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +01001071 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +00001072 * Functions requiring File System functions can now be disabled
1073 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +00001074 * A error_strerror function() has been added to translate between

1081 * Major argument / variable rewrite. Introduced use of size_t
1082 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001083 better unsigned / signed use. Renamed internal bigint types
1084 t_int and t_dbl to t_uint and t_udbl in the process

1086 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +00001087 * The error codes have been remapped and combining error codes
1088 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001089 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001090 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1091 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001092 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1093 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1094 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1095 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001096 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

1113 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001114 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +00001115
