Interface Encryptor

All Superinterfaces:

Destroyable

All Known Subinterfaces:

Cryptor

public interface Encryptor
extends Destroyable

This interface transforms a byte array such that later the original data can be restored with the "right" Decryptor.

Also, it is (more or less) difficult for an attacker to decrypt any encrypted data without the "right" Decryptor.
