iaik.pkcs.pkcs11.provider.random

Class PKCS11Random

java.lang.Object

java.util.Random

java.security.SecureRandom

iaik.pkcs.pkcs11.provider.random.PKCS11Random

All Implemented Interfaces:

java.io.Serializable

public class PKCS11Random
extends java.security.SecureRandom

An implementation of the SecureRandom that uses a PKCS#11 token to gereate random data. If this object is created using the default constructor, and this is always the case when instantiated through the JCA mechanism, this implementation always links to the first instance of IAIKPkcs11. To link to a different provider instance, instantiate the PKCS11Random class directly and specify the provide instance.

Constructor Detail

PKCS11Random

public PKCS11Random()
             throws IAIKPkcs11Exception

This default constructor always links this random class to the first provider instance, because there are no means in the JCE to find out our provider instance.

Throws:

IAIKPkcs11Exception - If there is no IAIKPkcs11 instance available.

PKCS11Random

public PKCS11Random(IAIKPkcs11 provider)
             throws IAIKPkcs11Exception

This constructor links this random class to the given provider instance. It uses the token manager of this provider to access the token.

Parameters:

provider - The IAIK PKCS#11 provider instance of this random object.

Throws:

IAIKPkcs11Exception - If there is no IAIKPkcs11 instance available.

Preconditions:

(provider <> null)

PKCS11Random

public PKCS11Random(java.security.SecureRandomSpi pkcs11RandomImplementation,
                    IAIKPkcs11 provider)
             throws IAIKPkcs11Exception

This constructor links this random class to the given provider instance. It uses the token manager of this provider to access the token. It uses the given implementation object to process the requests.

Parameters:

pkcs11RandomImplementation - The random implementation of this random object.

provider - The IAIK PKCS#11 provider instance of this random object.

Throws:

IAIKPkcs11Exception - If there is no IAIKPkcs11 instance available.

Preconditions:

(provider <> null)
