Interface StreamingEncryptionEngine

All Superinterfaces:

EncryptionEngine

All Known Implementing Classes:

CryptoSymmetricEngine

public interface StreamingEncryptionEngine
extends EncryptionEngine

Interface for encryption engines that adds possibility to encrypt and decrypt streams. Note that implementations should be immutable (should not change its internal state by any of the methods).
