mono/mcs/class/corlib/System.Security.Cryptography/ChangeLog

2003-01-05  Sebastien Pouliot  <[email protected]>

	* CryptoAPITransform.cs: Removed all TODO. This class will not be
	used by Mono. MS uses it with <algo>CryptoServiceProvider classes 
	to provide a common ICryptoTransform access to CryptoAPI. 

2003-01-03  Sebastien Pouliot  <[email protected]>

	* RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining 
	methods and changing to UInt16 (instead of UInt32). 

2003-01-02  Sebastien Pouliot  <[email protected]>

	* 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  <[email protected]>

	* AsymmetricAlgorithm.cs: Removed ValidKeySize (method only present
	in SymmetricAlgorithm).

	for keypairGenerated.
	* RSA.cs: Change ZeroizePrivateKey from protected to internal.

	(no parameter) constructor. Now checks for keypairGenerated in methods.
	* SignatureDescription.cs: Added CreateDeformatter in RSAPKCS1SHA1-
	SignatureDescription to please corcompare (it just call it's ancestor).

2002-12-30  Sebastien Pouliot  <[email protected]>

	but it run the samples now (#30256).

	member (because this created an unwanted "ghost" constructor) and 
	modified Dispose declaration.
	* HashAlgorithm.cs: Removed destructor. Disposing unmanaged 
	ressources is the responsability of each class (not an abstract class).
	* RSAPKCS1SignatureDeformatter.cs: Removed a VerifySignature method
	which was present in the base class AsymmetricSignatureDeformatter.
	* RSAPKCS1SignatureFormatter.cs: Removed a CreateSignature method

	Will dynamically load System.Security.dll, when required,
	to return instance of those classes. Also CryptoConfig can now

	interface for MiniParser) to import DSA keypairs from XML strings.
	* DSACryptoServiceProvider.cs: Crypto fully implemented using

	CryptoConfig - which actually can create anything). Added internal
	classes DSASignatureDescription and RSAPKCS1SHA1SignatureDescription.
