Paul Bakker7eb013f2011-10-06 12:37:39 +000018Features
19 * Added ssl_session_reset() to allow better multi-connection pools of
20 SSL contexts without needing to set all non-connection-specific
21 data and pointers again. Adapted ssl_server to use this functionality.
Paul Bakker490ecc82011-10-06 13:04:09 +000022 * Added ssl_set_max_version() to allow clients to offer a lower maximum
23 supported version to a server to help buggy server implementations.

35 encryption and private key for decryption. (Closes ticket #34)
Paul Bakkerc4909d92011-10-12 09:52:22 +000036 * Inceased maximum size of ASN1 length reads to 32-bits.
Paul Bakkerfbc09f32011-10-12 09:56:41 +000037 * Added an EXPLICIT tag number parameter to x509_get_ext()
Paul Bakkerb5a11ab2011-10-12 09:58:41 +000038 * Added a separate CRL entry extension parsing function
Paul Bakkerefc30292011-11-10 14:43:23 +000039 * Separated the ASN.1 parsing code from the X.509 specific parsing code.
40 So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C.
Paul Bakker5e18aed2011-11-15 15:38:45 +000041 * Changed the defined key-length of DES ciphers in cipher.h to include the
42 parity bits, to prevent mistakes in copying data. (Closes ticket #33)

46 trade-off

51 a consequence in library code and programs
Paul Bakker508ad5a2011-12-04 17:09:26 +000052 * Moved all examples programs to use the new entropy and CTR_DRBG
Paul Bakker6c0ceb32011-12-04 12:24:18 +000053 * Added permissive certificate parsing to x509parse_crt() and
54 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker69e095c2011-12-10 21:55:01 +000055 encountering a parse-error. Beware that the meaning of return values has
56 changed!
57 * All error codes are now negative. Even on mermory failures and IO errors.
Paul Bakkerca6f3e22011-10-06 13:11:08 +000058

Paul Bakkercebdf172011-11-11 15:01:31 +000064 * Allowed X509 key usage parsing to accept 4 byte values instead of the
65 standard 1 byte version sometimes used by Microsoft. (Closes ticket #38)
Paul Bakker1fe7d9b2011-11-15 15:26:03 +000066 * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
67 smaller than the hash length. (Closes ticket #41)
Paul Bakker03c7c252011-11-25 12:37:37 +000068 * If certificate serial is longer than 32 octets, serial number is now

92 enable and disable individual modes when needed

94 by undefining POLARSSL_FS_IO

96 error codes and their description.

Paul Bakker23986e52011-04-24 08:57:21 +0000101Changes
102 * Major argument / variable rewrite. Introduced use of size_t
103 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000104 better unsigned / signed use. Renamed internal bigint types
105 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000106 * mpi_init() and mpi_free() now only accept a single MPI
107 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000108 * The error codes have been remapped and combining error codes
109 is now done with a PLUS instead of an OR as error codes
110 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000111 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
112 net_recv() now returns 0 on EOF instead of
113 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
114 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
115 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
116 after the handshake.
117 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
118 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
119 POLARSSL_ERR_NET_TRY_AGAIN

132 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000133 * x509parse_key() (and as a consequence x509parse_keyfile())
134 does not zeroize memory in advance anymore. Use rsa_init()
135 before parsing a key or keyfile!

201 of ssl_session have been renamed to ciphersuites and
202 ciphersuite respectively. This clarifies the difference
203 with the generic cipher layer and is better naming
204 altogether
Paul Bakkerb6194992011-01-16 21:40:22 +0000205

362 * Added support for ciphersuite: SSL_RSA_AES_128_SHA
363 * Enabled support for large files by default in aescrypt2.c
364 * Preliminary openssl wrapper contributed by David Barrett
365 * Fixed a bug in ssl_write() that caused the same payload to
366 be sent twice in non-blocking mode when send returns EAGAIN
367 * Fixed ssl_parse_client_hello(): session id and challenge must
368 not be swapped in the SSLv2 ClientHello (found by Greg Robson)
369 * Added user-defined callback debug function (Krystian Kolodziej)
370 * Before freeing a certificate, properly zero out all cert. data
371 * Fixed the "mode" parameter so that encryption/decryption are
372 not swapped on PadLock; also fixed compilation on older versions
373 of gcc (bug reported by David Barrett)
374 * Correctly handle the case in padlock_xcryptcbc() when input or
375 ouput data is non-aligned by falling back to the software
376 implementation, as VIA Nehemiah cannot handle non-aligned buffers
377 * Fixed a memory leak in x509parse_crt() which was reported by Greg
378 Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to
379 Matthew Page who reported several bugs
380 * Fixed x509_get_ext() to accept some rare certificates which have
381 an INTEGER instead of a BOOLEAN for BasicConstraints::cA.

383 (patch contributed by David Patino)
384 * Make x509parse_verify() return BADCERT_CN_MISMATCH when an empty
385 string is passed as the CN (bug reported by spoofy)
386 * Added an option to enable/disable the BN assembly code
387 * Updated rsa_check_privkey() to verify that (D*E) = 1 % (P-1)*(Q-1)

389 selftest and benchmark to not test ciphers that have been disabled
390 * Updated x509parse_cert_info() to correctly display byte 0 of the
391 serial number, setup correct server port in the ssl client example
392 * Fixed a critical denial-of-service with X.509 cert. verification:
393 peer may cause xyssl to loop indefinitely by sending a certificate
394 for which the RSA signature check fails (bug reported by Benoit)
395 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
396 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
397 * Fixed HMAC-SHA-384 and HMAC-SHA-512 (thanks to Josh Sinykin)
398 * Modified ssl_parse_client_key_exchange() to protect against
399 Daniel Bleichenbacher attack on PKCS#1 v1.5 padding, as well
400 as the Klima-Pokorny-Rosa extension of Bleichenbacher's attack
401 * Updated rsa_gen_key() so that ctx->N is always nbits in size
