doesn't have access to the machine key store.

of SHA-224.

ICryptoTransform interface (TransformBlock, TransformFinalBlock).

2004-05-01 Sebastien Pouliot <sebastien@ximian.com>
* CryptoConvertTest.cs: Added test case where a strongname key pair
(RSA 1024 bits) was truncated in the last parameter (D) (i.e. the
private key) but saved by the use of CRT (Chinese Remainder Theorem).
2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
* CryptoConvertTest.cs: Added test case where the public key structure
is inside preceded by an header (like the one produced by "sn -e").
2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
* CryptoConvertTest.cs: New. Unit tests for CryptoConvert.
2004-02-13 Sebastien Pouliot <sebastien@ximian.com>

* MD4Test.cs: New. Contains all the test vectors provided in RFC1320
- but none are executed because MD4 is an abstract class.
* MD4ManagedTest.cs: New. Run the unit tests from MD4Test.cs using
the MD4Managed implementation of MD4.
* PKCS8Test.cs: New. Unit tests for PKCS8.
2003-03-07 Sebastien Pouliot <spouliot@videotron.ca>
* ARC4ManagedTest.cs: New. Test vectors for RC4(tm) taken from
usenet and Netscape SSL version 3 implementation details.
