Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +010016 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard4da88c52015-03-24 18:23:20 +010017 * Removed individual mdX_hmac and shaX_hmac functions (use generic

24 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
25 (support for renegotiation now needs explicit enabling in config.h).
26 * Remove compat-1.2.h (helper for migrating from 1.2 to 1.3).
27 * Remove openssl.h (very partial OpenSSL compatibility layer).
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +020028 * net_connect() and net_bind() have a new 'proto' argument to choose

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +020049 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
50 enabled in the default configuration, this is only noticeable if using a

1108 * Major argument / variable rewrite. Introduced use of size_t
1109 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001110 better unsigned / signed use. Renamed internal bigint types
1111 t_int and t_dbl to t_uint and t_udbl in the process

1120 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.

1122 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001123 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

1140 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001141 before parsing a key or keyfile!
