All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, org.refcodes.mixin.Disposable

public class EncryptionOutputStream
extends OutputStream
implements org.refcodes.mixin.Disposable

A EncryptionOutputStream wraps an OutputStream and produces output bytes by applying a Encrypter on each byte to be written before delegating the processed vale to the given OutputStream. The output of the EncryptionOutputStream can be converted back by the according DecryptionInputStream.
