74 SSL contexts without needing to set all non-connection-specific
75 data and pointers again. Adapted ssl_server to use this functionality.
Paul Bakker490ecc82011-10-06 13:04:09 +000076 * Added ssl_set_max_version() to allow clients to offer a lower maximum
77 supported version to a server to help buggy server implementations.

94 So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C.
Paul Bakker5e18aed2011-11-15 15:38:45 +000095 * Changed the defined key-length of DES ciphers in cipher.h to include the

Paul Bakker6c0ceb32011-12-04 12:24:18 +0000107 * Added permissive certificate parsing to x509parse_crt() and
108 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker69e095c2011-12-10 21:55:01 +0000109 encountering a parse-error. Beware that the meaning of return values has
110 changed!
111 * All error codes are now negative. Even on mermory failures and IO errors.

Paul Bakker1fe7d9b2011-11-15 15:26:03 +0000120 * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
121 smaller than the hash length. (Closes ticket #41)
Paul Bakker03c7c252011-11-25 12:37:37 +0000122 * If certificate serial is longer than 32 octets, serial number is now

148 by undefining POLARSSL_FS_IO

150 error codes and their description.
Paul Bakker2f5947e2011-05-18 15:47:11 +0000151 * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter

Paul Bakker23986e52011-04-24 08:57:21 +0000155Changes
156 * Major argument / variable rewrite. Introduced use of size_t
157 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000158 better unsigned / signed use. Renamed internal bigint types
159 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000160 * mpi_init() and mpi_free() now only accept a single MPI
161 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000162 * The error codes have been remapped and combining error codes
163 is now done with a PLUS instead of an OR as error codes
164 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000165 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
166 net_recv() now returns 0 on EOF instead of
167 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
168 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
169 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
170 after the handshake.
171 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
172 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
173 POLARSSL_ERR_NET_TRY_AGAIN

186 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000187 * x509parse_key() (and as a consequence x509parse_keyfile())
188 does not zeroize memory in advance anymore. Use rsa_init()
189 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +0000190

Paul Bakkere3166ce2011-01-27 17:40:50 +0000254 * The ciphers member of ssl_context and the cipher member
255 of ssl_session have been renamed to ciphersuites and
256 ciphersuite respectively. This clarifies the difference
257 with the generic cipher layer and is better naming
258 altogether
Paul Bakkerb6194992011-01-16 21:40:22 +0000259
