Paul Bakker6c0ceb32011-12-04 12:24:18 +0000134 * Added permissive certificate parsing to x509parse_crt() and
135 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker732e1a82011-12-11 16:35:09 +0000136 encountering a parse-error. Beware that the meaning of return values has
137 changed!

183 * Major argument / variable rewrite. Introduced use of size_t
184 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000185 better unsigned / signed use. Renamed internal bigint types
186 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000187 * mpi_init() and mpi_free() now only accept a single MPI

197 after the handshake.
198 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
199 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
200 POLARSSL_ERR_NET_TRY_AGAIN

213 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000214 * x509parse_key() (and as a consequence x509parse_keyfile())
215 does not zeroize memory in advance anymore. Use rsa_init()
216 before parsing a key or keyfile!
