103 So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C.
Paul Bakker5e18aed2011-11-15 15:38:45 +0000104 * Changed the defined key-length of DES ciphers in cipher.h to include the

117 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker69e095c2011-12-10 21:55:01 +0000118 encountering a parse-error. Beware that the meaning of return values has
119 changed!

165 * Major argument / variable rewrite. Introduced use of size_t
166 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000167 better unsigned / signed use. Renamed internal bigint types
168 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000169 * mpi_init() and mpi_free() now only accept a single MPI
170 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000171 * The error codes have been remapped and combining error codes

179 after the handshake.
180 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
181 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
182 POLARSSL_ERR_NET_TRY_AGAIN

195 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000196 * x509parse_key() (and as a consequence x509parse_keyfile())
197 does not zeroize memory in advance anymore. Use rsa_init()
198 before parsing a key or keyfile!
