Paul Bakker5e18aed2011-11-15 15:38:45 +000056 * Changed the defined key-length of DES ciphers in cipher.h to include the

66 a consequence in library code and programs
Paul Bakker508ad5a2011-12-04 17:09:26 +000067 * Moved all examples programs to use the new entropy and CTR_DRBG
Paul Bakker6c0ceb32011-12-04 12:24:18 +000068 * Added permissive certificate parsing to x509parse_crt() and
69 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker69e095c2011-12-10 21:55:01 +000070 encountering a parse-error. Beware that the meaning of return values has
71 changed!
72 * All error codes are now negative. Even on mermory failures and IO errors.

82 smaller than the hash length. (Closes ticket #41)
Paul Bakker03c7c252011-11-25 12:37:37 +000083 * If certificate serial is longer than 32 octets, serial number is now

117 * Major argument / variable rewrite. Introduced use of size_t
118 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000119 better unsigned / signed use. Renamed internal bigint types
120 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000121 * mpi_init() and mpi_free() now only accept a single MPI
122 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000123 * The error codes have been remapped and combining error codes
124 is now done with a PLUS instead of an OR as error codes
125 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000126 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
127 net_recv() now returns 0 on EOF instead of
128 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
129 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.

131 after the handshake.
132 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
133 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
134 POLARSSL_ERR_NET_TRY_AGAIN

147 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000148 * x509parse_key() (and as a consequence x509parse_keyfile())
149 does not zeroize memory in advance anymore. Use rsa_init()
150 before parsing a key or keyfile!

217 ciphersuite respectively. This clarifies the difference
218 with the generic cipher layer and is better naming
219 altogether
Paul Bakkerb6194992011-01-16 21:40:22 +0000220

388 of gcc (bug reported by David Barrett)
389 * Correctly handle the case in padlock_xcryptcbc() when input or
390 ouput data is non-aligned by falling back to the software
391 implementation, as VIA Nehemiah cannot handle non-aligned buffers

408 peer may cause xyssl to loop indefinitely by sending a certificate
409 for which the RSA signature check fails (bug reported by Benoit)
