291 * Major argument / variable rewrite. Introduced use of size_t
292 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100293 better unsigned / signed use. Renamed internal bigint types
294 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000295 * mpi_init() and mpi_free() now only accept a single MPI
296 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000297 * The error codes have been remapped and combining error codes
298 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100299 used are negative.

303 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
304 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
305 after the handshake.

552 * Enabled support for large files by default in aescrypt2.c

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

582 peer may cause xyssl to loop indefinitely by sending a certificate
583 for which the RSA signature check fails (bug reported by Benoit)
584 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
585 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
