2006-10-04 Sebastien Pouliot * PKCS1.cs: Remove compatibility block where all padding wasn't verified (can't find the original test case for it). Note: the existing implementation wasn't affected by CVE-2006-4339, aka RSA PKCS#1 1.5 signature forgery (but we're stronger without it). 2006-09-27 Sebastien Pouliot * RSAManaged.cs: Ensure that the results of Encrypt and Decrypt will always be the same length as the key. If smaller then we left pad the result with 0x00 (same integer, correct length for everyone).

See bug #77559. * PKCS8.cs: Make sure we can import a keypair into our RSA instance (even if the key store isn't available). See bug #77559. 2005-11-23 Sebastien Pouliot * SymmetricTransform.cs: Synched with corlib version (IV behaviour for NET_2_0). Virtualized some methods (like Dispose). Fix bug #76801. 2005-05-09 Sebastien Pouliot * KeyPairPersistence.cs: Use PlatformID.Unix under NET_2_0. * PKCS8.cs: In sync with corlib; 2005-04-18 Sebastien Pouliot * Null.cs: New "null" symmetric encryption for debugging.

The algorithm is OK but the check for IV, unused for stream ciphers, has changed. 2004-10-28 Sebastien Pouliot * KeyPairPersistence.cs: Added localization for exceptions messages. Also added more details (type and path) when an exception is thrown. 2004-09-29 Sebastien Pouliot * RSAManaged.cs: In synch with corlib. KeySize is now always a multiple of 8 bits. Fix #66929. 2004-09-17 Sebastien Pouliot * CryptoConvert.cs: In synch with corlib version. Fixed all level 4 compilation warnings. * KeyPairPersistence.cs: In synch with corlib version. Fixed all level 4 compilation warnings. * PKCS1.cs: In synch with corlib version.

This operation was in CryptoStream before but is only required for decryption (which CryptoStream can't know). Fix bug #60573. 2004-05-27 Sebastien Pouliot * ARC4Managed.cs: Added missing exception handling in TransformBlock and TransformFinalBlock. * SymmetricTransform.cs: Fixed possible integer overflow.

Fix #57941 (couldn't sign with nunit key). * RSAManaged.cs: Normalized the size of D when not present. This allows us to output a compatible base64 representation of 1024bits 0. 2004-04-28 Sebastien Pouliot * SymmetricTransform.cs: Fixed bug when offset > 0 in destination buffer. 2004-04-22 Sebastien Pouliot * CryptoConvert.cs: FxCop-ized.

Added new version of FromCapiPublicKeyBlob with an integer offset. 2004-03-10 Sebastien Pouliot * PKCS8.cs: Added EncodeRSA, EncodeDSA and completed GetBytes() so it is now possible to encode PKCS8 files (this is required to encode PKCS12 files). 2004-02-15 Sebastien Pouliot * ARC4Managed.cs: Removed all % 256 (modulo) because typecasting to byte already ensure the result would be correct (as suggested by Technoboy). Now use KeyBuilder to create new keys. 2004-02-13 Sebastien Pouliot * DHKeyGeneration.cs: New. Enumuration of possible key generation for Diffie-Hellman.
