2004-02-08  Sebastien Pouliot  <sebastien@ximian.com>

	* HashAlgorithm.cs: Changed the ComputeHash(Stream) method to (a) not
	allocate the whole stream memory (big memory saver as suggested by
	Peter Williams in bugzilla entry #54022) and (b) to never use Stream.
	Length and Stream.Position because they aren't implemented for every
	stream class (similar issue to the CryptoStream patch).
	* MD5CryptoServiceProvider.cs: Moved a buffer allocation from 
	ProcessBlock to constructor to reduce memory allocation. Optimization
	suggested by Peter Williams in bugzilla entry #54024.

	Corrected dispose so object cannot be disposed multiple time. Added
	PublicOnly property (as internal before 1.2, public after).

	class will also be included in Mono.Security assembly.

	with the class (Read/WriteByte, reading by non-multiple of the
	block size, using Stream.Length and Stream.Position ...).
	* SymmetricAlgorithm.cs: Return an empty array when there's nothing
	to return (required for CryptoStream to work).

2004-01-31  David Sheldon      <dave-mono@earth.li>

	* FromBase64Transform.cs: Removed needless catch and rethrow.

2004-01-31  David Sheldon      <dave-mono@earth.li>

	* FromBase64Transform.cs: Fixes to what happens if a character in the
	input stream is not in the lookup table. IndexOutOfRangeException was 
	wrong.

2003-12-15  Sebastien Pouliot  <spouliot@videotron.ca>

	* CryptoConfig.cs: Now use internal Environment.GetMachineConfigPath()
	to find machine.config.	Initialization removed from static constructor

	tests for padding modes are now in PaddingModeTest.cs.

	(like MS does but unlike MS documents).

2003-03-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	algorithm names documented in book ".NET Framework Security".

2003-02-03  Sebastien Pouliot  <spouliot@videotron.ca>

	* PasswordDeriveBytes.cs: Finally got the derivation right. The

	* RSAPKCS1SignatureDeformatter.cs: No need to create the hash object
	in this class - the OID is enough.

2003-01-05  Sebastien Pouliot  <spouliot@videotron.ca>

	* CryptoAPITransform.cs: Removed all TODO. This class will not be
