RSAdisposable

System.Security.Cryptography (mscorlib.dll)abstract class
public abstract class RSA : AsymmetricAlgorithm { // Public Constructors    public RSA(  ); // Public Static Methods    public static RSA Create(  );    public static RSA Create(string algName); // Public Instance Methods    public abstract byte[  ] DecryptValue(byte[  ] rgb);    public abstract byte[  ] EncryptValue(byte[  ] rgb);    public abstract RSAParameters ExportParameters(bool includePrivateParameters);    public override void FromXmlString(string xmlString);  // overrides AsymmetricAlgorithm    public abstract void ImportParameters(RSAParameters parameters);    public override string ToXmlString(bool includePrivateParameters);  // overrides AsymmetricAlgorithm }

This class extends AsymmetricAlgorithm and is the abstract representation of the RSA algorithm. Individual implementations of RSA will extend this class. RSA key pairs are represented by the RSAParameters structure, and can be imported and exported from the RSA class with the ImportParameters( ) and ExportParameters( ) methods.

The EncryptValue( ) and DecryptValue( ) methods defined by this class are not implemented by the RSACryptoServiceProvider class, which is the only implementation class included in the .NET Framework class library; data encryption must be performed by using methods defined in the implementation class.

This class does not define any members to support digital signatures; see the RSACryptoServiceProvider or the RSAPKCS1SignatureFormatter classes in this chapter for details of RSA digital signature support.
