Preconditions
(token <> null) and (publicKeyObject <> null)
Method Detail

create

public static IAIKPKCS11DsaPublicKey create(TokenManager tokenManager,
                                            iaik.pkcs.pkcs11.objects.DSAPublicKey publicKeyObject)
Create a new instance of a IAIKPKCS11DsaPublicKey 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 IAIKPKCS11DsaPublicKey that can be used with this provider.
Postconditions
(result <> null)

getY

public java.math.BigInteger getY()

Specified by:
getY in interface java.security.interfaces.DSAPublicKey
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 java.security.interfaces.DSAParams getParams()
Get the DSA parameters of this key.

Specified by:
getParams in interface java.security.interfaces.DSAKey
Returns:
The DSA 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:
"DSA".
Postconditions
(result <> null) and (result.equals("DSA"))
