Constructor Detail

IAIKPKCS11DhPublicKey

public IAIKPKCS11DhPublicKey(TokenManager tokenManager,
                             iaik.pkcs.pkcs11.objects.DHPublicKey publicKeyObject)

Construct a public key object that is associated with the given publickeyObjecton the given token.

Parameters:

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

publicKeyObject - The PKCS#11 key object.

Preconditions:

(token <> null) and (publicKeyObject <> null)

Method Detail

create

public static IAIKPKCS11DhPublicKey create(TokenManager tokenManager,
                                           iaik.pkcs.pkcs11.objects.DHPublicKey publicKeyObject)

Create a new instance of a IAIKPKCS11DhPublicKey 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.

publicKeyObject - The PKCS#11 key object.

Returns:

A new IAIKPKCS11DhPublicKey that can be used with this provider.

Postconditions:

(result <> null)

getY

public java.math.BigInteger getY()

Get the public value Y of this key.

Specified by:

getY in interface javax.crypto.interfaces.DHPublicKey

Returns:

The public value Y.

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 IAIKPKCS11PublicKey

Returns:

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