Constructor Detail

IAIKPKCS11DhPrivateKey

public IAIKPKCS11DhPrivateKey(TokenManager tokenManager,
                              iaik.pkcs.pkcs11.objects.DHPrivateKey privateKeyObject)

Construct a private key object that is associated with the given privatekeyObjecton the given token.

Parameters:

tokenManager - The token manager of the token where this key resides.

privateKeyObject - The PKCS#11 key object.

Preconditions:

(token <> null) and (privateKeyObject <> null)

Method Detail

create

public static IAIKPKCS11DhPrivateKey create(TokenManager tokenManager,
                                            iaik.pkcs.pkcs11.objects.DHPrivateKey privateKeyObject)

Create a new instance of a IAIKPKCS11DhPrivateKey which's token managed by the given token manager and is based on the given PKCS#11 key object.

Parameters:

tokenManager - The token manager of the token where the key is.

privateKeyObject - The PKCS#11 key object.

Returns:

A new IAIKPKCS11DhPrivateKey that can be used with this provider.

Postconditions:

(result <> null)

getX

public java.math.BigInteger getX()

Get the private value X of this key.

Specified by:

getX in interface javax.crypto.interfaces.DHPrivateKey

Returns:

The private value X.

Throws:

java.lang.UnsupportedOperationException - If the value is not present or if the value is sensitive.

Postconditions:

(result <> null)

getParams

public javax.crypto.spec.DHParameterSpec getParams()

Get the DH parameters of this key.

Specified by:

getParams in interface javax.crypto.interfaces.DHKey

Returns:

The DH parameters.

Throws:

java.lang.UnsupportedOperationException - If the value is not present or if the value is sensitive.

Postconditions:

(result <> null)

getAlgorithm

public java.lang.String getAlgorithm()

Get the algorithm name.

Specified by:

getAlgorithm in interface java.security.Key

Overrides:

getAlgorithm in class IAIKPKCS11Key

Returns:

"DH".

Postconditions:

(result <> null) and (result.equals("DH"))

getKeyFactory

protected java.security.KeyFactory getKeyFactory()

Get a key factory that can encode this key according to X.509.

Overrides:

getKeyFactory in class IAIKPKCS11PrivateKey

Returns:

A key factory which can encode this key or null if there is no such key factory available.
