|  | certificate. If the user-supplied chain contains only one certificates, | 
|  | it is not affected (ie, its notAfter date is properly checked). |

|  | * oid_get_numeric_string() used to truncate the output without returning an | 
|  | error if the output buffer was just 1 byte too small. | 
|  | * dhm_parse_dhm() (hence dhm_parse_dhmfile()) did not set dhm->len. | 
|  | * Calling pk_debug() on an RSA-alt key would segfault. | 
|  | * pk_get_size() and pk_get_len() were off by a factor 8 for RSA-alt keys. | 
|  | * Potential buffer overwrite in pem_write_buffer() because of low length | 
|  | indication (found by Thijs Alkemade) | 
|  | * EC curves constants, which should be only in ROM since 1.3.3, were also | 
|  | stored in RAM due to missing 'const's (found by Gergely Budai). |

|  | testing against GnuTLS |

|  |  |

|  | SSL contexts without needing to set all non-connection-specific | 
|  | data and pointers again. Adapted ssl_server to use this functionality. |

|  | supported version to a server to help buggy server implementations. | 
|  | (Closes ticket #36) | 
|  | * Added cipher_get_cipher_mode() and cipher_get_cipher_operation() | 
|  | introspection functions (Closes ticket #40) | 
|  | * Added CTR_DRBG based on AES-256-CTR (NIST SP 800-90) random generator |

|  | custom entropy sources and added some generic and platform dependent | 
|  | entropy sources | 
|  |  | 
|  | Changes | 
|  | * Documentation for AES and Camellia in modes CTR and CFB128 clarified. | 
|  | * Fixed rsa_encrypt and rsa_decrypt examples to use public key for | 
|  | encryption and private key for decryption. (Closes ticket #34) | 
|  | * Inceased maximum size of ASN1 length reads to 32-bits. | 
|  | * Added an EXPLICIT tag number parameter to x509_get_ext() | 
|  | * Added a separate CRL entry extension parsing function | 
|  | * Separated the ASN.1 parsing code from the X.509 specific parsing code. | 
|  | So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C. |

|  | parity bits, to prevent mistakes in copying data. (Closes ticket #33) |

|  | management (Closes ticket #44) | 
|  | * Changed the used random function pointer to more flexible format. Renamed | 
|  | havege_rand() to havege_random() to prevent mistakes. Lots of changes as | 
|  | a consequence in library code and programs | 
|  | * Moved all examples programs to use the new entropy and CTR_DRBG | 
|  | * Added permissive certificate parsing to x509parse_crt() and | 
|  | x509parse_crtfile(). With permissive parsing the parsing does not stop on | 
|  | encountering a parse-error. Beware that the meaning of return values has | 
|  | changed! | 
|  | * All error codes are now negative. Even on mermory failures and IO errors. | 
|  |  | 
|  | Bugfix | 
|  | * Fixed faulty HMAC-MD2 implementation. Found by dibac. (Closes | 
|  | ticket #37) | 
|  | * Fixed a bug where the CRL parser expected an EXPLICIT ASN.1 tag | 
|  | before version numbers | 
|  | * Allowed X509 key usage parsing to accept 4 byte values instead of the | 
|  | standard 1 byte version sometimes used by Microsoft. (Closes ticket #38) | 
|  | * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length | 
|  | smaller than the hash length. (Closes ticket #41) | 
|  | * If certificate serial is longer than 32 octets, serial number is now | 
|  | appended with '....' after first 28 octets | 
|  | * Improved build support for s390x and sparc64 in bignum.h | 
|  | * Fixed MS Visual C++ name clash with int64 in sha4.h | 
|  | * Corrected removal of leading "00:" in printing serial numbers in | 
|  | certificates and CRLs | 
|  |  |

|  | #18) |

|  | * Added additional Cipher Block Modes to symmetric ciphers | 
|  | (AES CTR, Camellia CTR, XTEA CBC) including the option to | 
|  | enable and disable individual modes when needed | 
|  | * Functions requiring File System functions can now be disabled | 
|  | by undefining POLARSSL_FS_IO | 
|  | * A error_strerror function() has been added to translate between | 
|  | error codes and their description. | 
|  | * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter | 
|  | functions. | 
|  | * Added ssl_mail_client and ssl_fork_server as example programs. | 
|  |  | 
|  | Changes | 
|  | * Major argument / variable rewrite. Introduced use of size_t | 
|  | instead of int for buffer lengths and loop variables for | 
|  | better unsigned / signed use. Renamed internal bigint types | 
|  | t_int and t_dbl to t_uint and t_udbl in the process | 
|  | * mpi_init() and mpi_free() now only accept a single MPI | 
|  | argument and do not accept variable argument lists anymore. | 
|  | * The error codes have been remapped and combining error codes | 
|  | is now done with a PLUS instead of an OR as error codes | 
|  | used are negative. | 
|  | * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv(). | 
|  | net_recv() now returns 0 on EOF instead of | 
|  | POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns | 
|  | POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function. | 
|  | ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received | 
|  | after the handshake. | 
|  | * Network functions now return POLARSSL_ERR_NET_WANT_READ or | 
|  | POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous | 
|  | POLARSSL_ERR_NET_TRY_AGAIN | 
|  |  | 
|  | = Version 0.99-pre4 released on 2011-04-01 |

|  | * Reading of Public Key files incorporated into default x509 | 
|  | functionality as well. | 
|  | * Added mpi_fill_random() for centralized filling of big numbers | 
|  | with random data (Fixed ticket #10) | 
|  |  | 
|  | Changes | 
|  | * Debug print of MPI now removes leading zero octets and | 
|  | displays actual bit size of the value. | 
|  | * x509parse_key() (and as a consequence x509parse_keyfile()) | 
|  | does not zeroize memory in advance anymore. Use rsa_init() | 
|  | before parsing a key or keyfile! | 
|  |  | 
|  | Bugfix | 
|  | * Debug output of MPI's now the same independent of underlying | 
|  | platform (32-bit / 64-bit) (Fixes ticket #19, found by Mads | 
|  | Kiilerich and Mihai Militaru) |

|  | after 1950 |

|  | (found by Mads Kiilerich) | 
|  | * Support more exotic name representations when parsing | 
|  | certificates (found by Mads Kiilerich) |

|  | found by Boris Krasnovskiy) | 
|  |  | 
|  | Security fixes |

|  | Diffie Hellman key exchange (thanks to Larry Highsmith, |

|  | the existing date check | 
|  | * The ciphers member of ssl_context and the cipher member | 
|  | of ssl_session have been renamed to ciphersuites and | 
|  | ciphersuite respectively. This clarifies the difference | 
|  | with the generic cipher layer and is better naming | 
|  | altogether |

|  | * Fixed a bug in ssl_write() that caused the same payload to | 
|  | be sent twice in non-blocking mode when send returns EAGAIN |

|  | not be swapped in the SSLv2 ClientHello (found by Greg Robson) | 
|  | * Added user-defined callback debug function (Krystian Kolodziej) | 
|  | * Before freeing a certificate, properly zero out all cert. data |

|  | not swapped on PadLock; also fixed compilation on older versions | 
|  | of gcc (bug reported by David Barrett) | 
|  | * Correctly handle the case in padlock_xcryptcbc() when input or | 
|  | ouput data is non-aligned by falling back to the software | 
|  | implementation, as VIA Nehemiah cannot handle non-aligned buffers | 
|  | * Fixed a memory leak in x509parse_crt() which was reported by Greg | 
|  | Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to | 
|  | Matthew Page who reported several bugs |

|  | (patch contributed by David Patino) |

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