All Implemented Interfaces:

PKCS11EngineClass

public class Sha256KeyDerivation
extends PKCS11KeyDerivation

This is a key generator that derives secret keys on a token using SHA-256. Through a PKCS11KeyDerivationSpec parameters object, the application can control the derivation of new keys; e.g. specify the base key and an attribute template for the new key.
