public interface ByteArrayCipherEngine
extends CipherEngine

Generic Cipher engine for encrypting/decrypting data that is supplied by a byte array. Used by class EncryptedContentInfo for content en/decryption. Setups a cipher utility for encryption/decryption depending on the requested mode and en/deciphers the data that is supplied to method cipher.

Allows the implementation of en/deciphering utilities that may be independent from the JCE javax.crypto.Cipher engine. The default implementation, however, is based on the javax.crypto.Cipher engine.

An application that implements its own ByteArrayCipherEngine has to obverride the following SecurityProvider methods to plug-in its own implementation:
