127 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker69e095c2011-12-10 21:55:01 +0000128 encountering a parse-error. Beware that the meaning of return values has
129 changed!

175 * Major argument / variable rewrite. Introduced use of size_t
176 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000177 better unsigned / signed use. Renamed internal bigint types
178 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000179 * mpi_init() and mpi_free() now only accept a single MPI
180 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000181 * The error codes have been remapped and combining error codes

189 after the handshake.

191 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
192 POLARSSL_ERR_NET_TRY_AGAIN

205 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000206 * x509parse_key() (and as a consequence x509parse_keyfile())
207 does not zeroize memory in advance anymore. Use rsa_init()
208 before parsing a key or keyfile!
