All Implemented Interfaces:

PKCS11EngineClass

public class DesEdeKeyGenerator
extends PKCS11KeyGenerator

This is a key generator that generates tripple DES keys on a token. Through a PKCS11KeyGenerationSpec parameters object, the application can control the generation of keys; e.g. give a key template.

The supported key sizes are 168 and 192 bit, default is 168 bit. Both values result in key with 192 bit but 168 effective key bits.
