This class defines several new members in addition to those of the RSA class; the Encrypt( ) and Decrypt( ) methods encrypt and decrypt System.Byte arrays with the RSA algorithm. The SignHash( ) and VerifyHash( ) methods create and verify digital signatures for cryptographic hash codes. The SignData( ) method creates a cryptographic hash code for data read from a System.IO.Stream or a System.Byte array and creates a signature for the result.
RSACryptoServiceProvider does not implement the EncryptValue( ) and DecryptValue( ) methods defined in the RSA class.
