134 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker732e1a82011-12-11 16:35:09 +0000135 encountering a parse-error. Beware that the meaning of return values has
136 changed!

182 * Major argument / variable rewrite. Introduced use of size_t
183 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000184 better unsigned / signed use. Renamed internal bigint types
185 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000186 * mpi_init() and mpi_free() now only accept a single MPI

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

Paul Bakker98675492011-03-26 13:17:12 +0000213 * x509parse_key() (and as a consequence x509parse_keyfile())
214 does not zeroize memory in advance anymore. Use rsa_init()
215 before parsing a key or keyfile!
