Class CompactEncryption

java.lang.Object

com.hissenit.crypto.compactencryption.CompactEncryption

public class CompactEncryption
extends java.lang.Object

For large objects and streams, it is much more efficient to use CompactBinarystreamEncryption.

This class does not support multithreading except for the getJCE* methods. The IV received through this class is for external use only. The compact format always creates and stores a fresh IV automatically. The last IV used can always be read.
