This subclass of DSA is the default implementation of the DSA and is a wrapper around the Windows Crypto API.

This class defines several new members; the SignData( ) method creates a digital signature by reading data from a stream. The VerifyData( ) method verifies a digital signature from the signed data (as opposed to the cryptographic hash code). The SignHash( ) and VerifyHash( ) methods are functionally equivalent to the CreateSignature( ) and VerifySignature( ) methods of the parent class.
