System.Security.Cryptography (mscorlib.dll)abstract class
public abstract class AsymmetricSignatureDeformatter { // Public Constructors    public AsymmetricSignatureDeformatter(  ); // Public Instance Methods    public abstract void SetHashAlgorithm(string strName);    public abstract void SetKey(AsymmetricAlgorithm key);    public abstract bool VerifySignature(byte[  ] rgbHash, byte[  ] rgbSignature);    public virtual bool VerifySignature(HashAlgorithm hash, byte[  ] rgbSignature); }

Implementations of this abstract class verify digital signatures created by the AsymmetricSignatureFormatter class.

The VerifySignature( ) method uses an asymmetric public key to verify a digital signature, expressed as a System.Byte array. The public key value is set by the SetKey( ) method, which accepts an instance of the AsymmetricAlgorithm class configured with the key parameters. The SetHashAlgorithm( ) method sets the name of the hash algorithm used to create the digital signature; this value is used in the verification process.

The .NET Framework class library includes the DSASignatureDeformatter and RSAPKCS1SignatureDeformatter classes, which verify digital signatures created with the DSASignatureFormatter and RSAPKCS1SignatureFormatter classes.
