All Implemented Interfaces:

PKCS11EngineClass

public class AesCbcEncryptDataKeyDerivation
extends PKCS11KeyDerivation

This is a key generator that derives secret keys on a token using DES-ECB data encryption. 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.

Instantiates a new derivation object.

Method Detail

getMechanism

protected iaik.pkcs.pkcs11.Mechanism getMechanism()

Description copied from class: PKCS11KeyGenerator

Get the mechanism that this key generator uses.

Specified by:

getMechanism in class PKCS11KeyGenerator

Returns:

The mechanism that this key generator uses.

getParameters

protected iaik.pkcs.pkcs11.parameters.Parameters getParameters()

Description copied from class: PKCS11KeyDerivation

Gets the parameters that this key generator needs. This returns null by default. Override if necessary.

Overrides:

getParameters in class PKCS11KeyDerivation

Returns:

the parameters. defaults to null.

getAlgorithmName

protected java.lang.String getAlgorithmName()

Description copied from class: PKCS11KeyGenerator

Get the JCE algorithm name, e.g. AES, DESede or RC4.

Specified by:

getAlgorithmName in class PKCS11KeyGenerator

Returns:

The JCE algorithm name.

engineInit

protected void engineInit(java.security.spec.AlgorithmParameterSpec params,
                          java.security.SecureRandom random)
                   throws java.security.InvalidAlgorithmParameterException

Description copied from class: PKCS11KeyDerivation

Initializes this key derivator with given algorithm parameters and random seed.

Overrides:

engineInit in class PKCS11KeyDerivation

Parameters:

params - The algorithm parameters, which must be an instance of PKCS11KeyDerivationSpec and must not be null.

random - This implementation ignores this parameter.

Throws:

java.security.InvalidAlgorithmParameterException - if the given algorithm parameters do not match to this KeyGenerator
