2003-04-06 Sebastien Pouliot * CryptoStream.cs: Partial fix for bug #40689 (workaround). Does not throw a NotSupportedException on closing a CryptoStream in read mode (like MS does but unlike MS documents). 2003-03-28 Gonzalo Paniagua Javier * CryptoStream.cs: fixed the previous fix. MS throws a NotSupportedExc when FlushFinalBlock is called twice. I've moved a few lines from Close to FlushFinalBlock and added the exception check. 2003-03-28 Gonzalo Paniagua Javier * CryptoStream.cs: don't Close the underlying stream in FlushFinalBlock. Fixes bug #40394. 2003-03-03 Sebastien Pouliot * RSACryptoServiceProvider.cs: Delay keypair generation event when keysize is a constructor parameter (major speed improvment when importing keys). Removed NotSupportedException when CspParameter is used in constructor (required for forthcoming security tools). 2003-02-08 Sebastien Pouliot * Changes to refer Mono.Math and Mono.Security.Cryptography * Changes to refer Mono.Xml 2003-02-04 Sebastien Pouliot * CryptoConfig.cs: Added initital support for "machine.config" (limited to algorithms, not OIDs). Modified CreateFromName to use the fully qualified class names (and removed xmldsig hack). Added algorithm names documented in book ".NET Framework Security". 2003-02-03 Sebastien Pouliot * PasswordDeriveBytes.cs: Finally got the derivation right. The class can now derive keys up to 1000 * HashSize (same limit as MS). * RSAPKCS1SignatureDeformatter.cs: No need to create the hash object in this class - the OID is enough. 2003-02-01 Sebastien Pouliot * AsymmetricSignatureFormatter.cs: Call abstract SetHashAlgorithm when CreateSignature(hash) is called. * CryptoStream.cs: Fixed some issues in constructor. * DSACryptoServiceProvider.cs: Fixed a bug (1 chance in 256) that a signature could be less than 40 bytes (which is invalid). 2003-01-25 Sebastien Pouliot * CryptographicException.cs: Default HResult to CORSEC_E_CRYPTO (0x80131430) as documented. * CryptographicUnexpectedOperationException.cs: Default HResult to CORSEC_E_CRYPTO_UNEX_OPER (0x80131431) as documented. 2003-01-20 Sebastien Pouliot * CipherMode.cs: Added missing [Serializable] to enum. * CspProviderFlags.cs: Added missing [Serializable] to enum. * FromBase64Transform.cs: Added missing [Serializable] to enum. * PaddingMode.cs: Added missing [Serializable] to enum. 2003-01-19 Sebastien Pouliot * CryptoTools.cs: Added internal class BlockProcessor to help implementation of block-based algorithms (like MAC and HMAC). * HMACSHA1.cs: Refactored to remove dependencies on CryptoStream, better constructors and Dispose support. * MACTripleDES.cs: Refactored to reuse new HMACSHA1 stuff, better constructors. 2003-01-18 Sebastien Pouliot * HMACSHA1.cs: Now use KeyBuilder to build the default key. 2003-01-12 Sebastien Pouliot * MACTripleDES.cs: Now working (the problem was with my stream usage which was removed for performance reason). * TripleDES.cs: Fixed key generation (wasn't called and returned null). 2003-01-09 Sebastien Pouliot * RNGCryptoServiceProvider.cs: Changed methods interacting with the runtime as Internal. This will allow to make the class Windows-compatible by doing a switch at runtime. 2003-01-05 Sebastien Pouliot * CryptoAPITransform.cs: Removed all TODO. This class will not be used by Mono. MS uses it with CryptoServiceProvider classes to provide a common ICryptoTransform access to CryptoAPI. 2003-01-03 Sebastien Pouliot * RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining methods and changing to UInt16 (instead of UInt32). 2003-01-02 Sebastien Pouliot * RijndaelManaged.cs: Now 7 (encrypt) to 10 (decrypt) times faster by removing allocation inside intensively called methods, using pre- calculated tables instead of Mult_GF methods and inlining most methods. 2002-12-31 Sebastien Pouliot * AsymmetricAlgorithm.cs: Removed ValidKeySize (method only present in SymmetricAlgorithm). * DSA.cs: Change ZeroizePrivateKey from protected to internal. * DSACryptoServiceProvider.cs: Added some case where we need to check for keypairGenerated. * RSA.cs: Change ZeroizePrivateKey from protected to internal. * RSACryptoServiceProvider.cs: Key were never generated with the default (no parameter) constructor.

Not sure about many details - but it run the samples now (#30256). * CryptoStreamMode.cs: Added [Serializable] to enum declaration. * SymmetricAlgorithm.cs: Made some changes required for CryptoStream and to match more closely MS implementation.

Key generation is VERY LONG. * RSAOAEPKeyExchangeDeformatter.cs: Completed using PKCS1. Not sure of the results as this is not available in all versions of Windows. * RSAOAEPKeyExchangeFormatter.cs: Completed using PKCS1.

Also CryptoConfig can now create any object (e.g. System.IO.MemoryStream) ! * DSA.cs: Added internal class DSAHandler (which implements IHandler interface for MiniParser) to import DSA keypairs from XML strings. * DSACryptoServiceProvider.cs: Crypto fully implemented using BigInteger. Key generation (group) is VERY long. * MiniParser.cs: New. Minimal XML parser by Sergey Chaban. Used to import keypairs in XML strings. * SignatureDescription.cs: Removed local CreateFromName (to use CryptoConfig - which actually can create anything).
