keyGenerator
Class KeyGeneratorController

java.lang.Object
  keyGenerator.KeyGeneratorController

All Implemented Interfaces:

KeyGeneratorInterface

public class KeyGeneratorController
extends java.lang.Object
implements KeyGeneratorInterface

Controller class of component KeyGenerator. Implements the architecture interface KeyGeneratorInterface.

Used to generate cryptographic keys. A class constant with public accessibility is available for each supported type of key.

Example of usage:

KeyGeneratorController kgc = new KeyGeneratorController(); KeyPair kp = (KeyPair) kgc.generateKey(KeyGeneratorController.KEY_PAIR);
