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:
