iaik.pkcs.pkcs11.provider.keygenerators.DesKeyGenerator

All Implemented Interfaces:

PKCS11EngineClass

public class DesKeyGenerator
extends PKCS11KeyGenerator

This is a key generator that generates 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 56 and 64 bit, default is 56 bit. Both values result in key with 64 bit but 56 effective key bits.
