        public byte[] decrypt​(byte[] ciphertext)
                       throws NotInitializedException,
                              java.security.GeneralSecurityException,
                              TokenException
        Decrypts the given ciphertext. It must have been created previously with the SecretDecoderRing, either the JSS version or the NSS version. The key used for decryption must exist on the token that was passed into the constructor. The token will be searched for a key whose keyID matches the keyID in the encoded SecretDecoderRing result.
        Parameters:
        ciphertext - A DER-encoded Encoding object, created from a previous call to Encryptor.encrypt(), or with the NSS SecretDecoderRing.
        Returns:
        The decrypted plaintext.
        Throws:
        java.security.InvalidKeyException - If no key can be found with the matching keyID.
        NotInitializedException
        java.security.GeneralSecurityException
        TokenException
