This class extends AsymmetricAlgorithm and is the
abstract representation of the Digital Signature Algorithm (DSA).
Individual implementations of DSA will extend this class. The .NET
Framework class library includes the
DSACryptoServiceProvider class, which is the
default implementation of the algorithm.
DSA key pairs are represented by the DSAParameters
structure, and can be imported and exported from the
DSA class with the ImportParameters(
) and ExportParameters( ) methods. The
CreateSignature( ) method produces a digital
signature for a cryptographic hash code, which can be verified using
the VerifySignature( ) method.
The DSA algorithm does not support data encryption.
