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()

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"))
