Paul Bakkera35aa542013-03-06 17:06:21 +01001054 encountering a parse-error. Beware that the meaning of return values has
1055 changed!

Paul Bakker335db3f2011-04-25 15:28:35 +00001092 * Functions requiring File System functions can now be disabled
1093 by undefining POLARSSL_FS_IO

1101 * Major argument / variable rewrite. Introduced use of size_t
1102 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001103 better unsigned / signed use. Renamed internal bigint types
1104 t_int and t_dbl to t_uint and t_udbl in the process

1108 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001109 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001110 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1111 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001112 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1113 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1114 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1115 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001116 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

1133 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001134 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +00001135
