475 2004-02-26 Sebastien Pouliot <sebastien@ximian.com>
477 * DES.cs: Same fix as for SymmetricAlgorithm (get_Key is
478 overridden to check for weak keys). Also ensured that no weak keys
480 * SymmetricAlgorithm.cs: Return a copy of the key (and IV) so it
481 doesn't get destroyed when dispose is called (in this case the key
482 zeroization is the caller's responsability). Match MS implementation.
483 * TripleDES.cs: Same fix as for SymmetricAlgorithm (get_Key is

497 CspParameters is supplied (or not) to the constructor.
498 * RSACryptoServiceProvider.cs: Same fixes as DSA.
499 * SymmetricAlgorithm.cs: Reintroduced the patch from 2003-08-24 to fix

503 2004-02-08 Sebastien Pouliot <sebastien@ximian.com>
505 * HashAlgorithm.cs: Changed the ComputeHash(Stream) method to (a) not
506 allocate the whole stream memory (big memory saver as suggested by
507 Peter Williams in bugzilla entry #54022) and (b) to never use Stream.
508 Length and Stream.Position because they aren't implemented for every
509 stream class (similar issue to the CryptoStream patch).
510 * MD5CryptoServiceProvider.cs: Moved a buffer allocation from
511 ProcessBlock to constructor to reduce memory allocation. Optimization
512 suggested by Peter Williams in bugzilla entry #54024.
514 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
516 * DSACryptoServiceProvider.cs: Added keypair persistence support.

518 PublicOnly property (as internal before 1.2, public after).
519 * RSACryptoServiceProvider.cs: Added keypair persistence support.
520 Corrected dispose so object cannot be disposed multiple time. Added
521 PublicOnly property (as internal before 1.2, public after).
522 * SymmetricAlgorithm.cs: Removed class SymmetricTransform from file

734 (like MS does but unlike MS documents).
736 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
738 * CryptoStream.cs: fixed the previous fix. MS throws a NotSupportedExc
739 when FlushFinalBlock is called twice. I've moved a few lines from Close
740 to FlushFinalBlock and added the exception check.
742 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
744 * CryptoStream.cs: don't Close the underlying stream in FlushFinalBlock.
747 2003-03-03 Sebastien Pouliot <spouliot@videotron.ca>
749 * RSACryptoServiceProvider.cs: Delay keypair generation event when
750 keysize is a constructor parameter (major speed improvment when
751 importing keys). Removed NotSupportedException when CspParameter is
752 used in constructor (required for forthcoming security tools).
754 2003-02-08 Sebastien Pouliot <spouliot@videotron.ca>
756 * Changes to refer Mono.Math and Mono.Security.Cryptography
757 * Changes to refer Mono.Xml
759 2003-02-04 Sebastien Pouliot <spouliot@videotron.ca>
761 * CryptoConfig.cs: Added initital support for "machine.config"
762 (limited to algorithms, not OIDs). Modified CreateFromName to use
763 the fully qualified class names (and removed xmldsig hack). Added
764 algorithm names documented in book ".NET Framework Security".
766 2003-02-03 Sebastien Pouliot <spouliot@videotron.ca>
768 * PasswordDeriveBytes.cs: Finally got the derivation right. The
769 class can now derive keys up to 1000 * HashSize (same limit as MS).
770 * RSAPKCS1SignatureDeformatter.cs: No need to create the hash object
771 in this class - the OID is enough.
773 2003-02-01 Sebastien Pouliot <spouliot@videotron.ca>
775 * AsymmetricSignatureFormatter.cs: Call abstract SetHashAlgorithm
776 when CreateSignature(hash) is called.

821 2003-01-05 Sebastien Pouliot <spouliot@videotron.ca>
823 * CryptoAPITransform.cs: Removed all TODO. This class will not be
824 used by Mono. MS uses it with <algo>CryptoServiceProvider classes
825 to provide a common ICryptoTransform access to CryptoAPI.
827 2003-01-03 Sebastien Pouliot <spouliot@videotron.ca>
829 * RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining

832 2003-01-02 Sebastien Pouliot <spouliot@videotron.ca>
834 * RijndaelManaged.cs: Now 7 (encrypt) to 10 (decrypt) times faster
835 by removing allocation inside intensively called methods, using pre-
836 calculated tables instead of Mult_GF methods and inlining most methods.

847 (no parameter) constructor. Now checks for keypairGenerated in methods.
848 * SignatureDescription.cs: Added CreateDeformatter in RSAPKCS1SHA1-
849 SignatureDescription to please corcompare (it just call it's ancestor).
851 2002-12-30 Sebastien Pouliot <spouliot@videotron.ca>

882 CreateSignature (moved from RSAPKCS1SignatureFormatter).
883 * CryptoAPITransform.cs: Removed "= false" assignation from a private
884 member (because this created an unwanted "ghost" constructor) and
885 modified Dispose declaration.
886 * HashAlgorithm.cs: Removed destructor. Disposing unmanaged
887 ressources is the responsability of each class (not an abstract class).
888 * RSAPKCS1SignatureDeformatter.cs: Removed a VerifySignature method
889 which was present in the base class AsymmetricSignatureDeformatter.
890 * RSAPKCS1SignatureFormatter.cs: Removed a CreateSignature method

924 * BigInteger.cs: New. Internal class for handling BIG integers for
925 asymmetric crypto (both RSA and DSA). Thanks to Chew Keong TAN !
926 * CryptoConfig.cs: Added XMLDSIG URLs in CreateFromName.
927 Will dynamically load System.Security.dll, when required,
928 to return instance of those classes. Also CryptoConfig can now
929 create any object (e.g. System.IO.MemoryStream) !
930 * DSA.cs: Added internal class DSAHandler (which implements IHandler
931 interface for MiniParser) to import DSA keypairs from XML strings.
932 * DSACryptoServiceProvider.cs: Crypto fully implemented using
933 BigInteger. Key generation (group) is VERY long.
934 * MiniParser.cs: New. Minimal XML parser by Sergey Chaban. Used to
935 import keypairs in XML strings.
936 * SignatureDescription.cs: Removed local CreateFromName (to use
937 CryptoConfig - which actually can create anything). Added internal
938 classes DSASignatureDescription and RSAPKCS1SHA1SignatureDescription.
940 2002-11-15 Sebastien Pouliot <spouliot@videotron.ca>
