All Implemented Interfaces:

PKCS11EngineClass

public class ExternalSha384RsaPssSignature
extends ExternalHashSignature

This is an implementation of a Signature class that uses the IAIK PKCS#11 wrapper to access the token. It only works with IAIKPKCS11PrivateKey and IAIKPKCS11PublicKey. This version uses the CKM_RSA_PKCS_PSS mechanism to create the signature; i.e. it creates the hash off-card. After hashing it send the generated hash to the token for signing. This class uses SHA-384 as hashing algorithm.

Constructor Detail

ExternalSha384RsaPssSignature

public ExternalSha384RsaPssSignature()

Public default constructor to enable instantiation via Class.forName(String).

Method Detail

getAlgorithmName

protected java.lang.String getAlgorithmName()

Get the JCA standard name of this signautre algorithm.

Specified by:

getAlgorithmName in class PKCS11Signature

Returns:

The JCA standard name of this signautre algorithm.

Postconditions:

(result <> null)

pkcs11SetParameter

protected void pkcs11SetParameter(java.security.spec.AlgorithmParameterSpec parametersSpec)
                           throws java.security.InvalidAlgorithmParameterException

SPI: Set the parameters for this signature object. For this implementation, the parametersSpec must be a PKCS11SignatureParameterSpec that contains the PKCS#11 parameters for this signature mechanism.

Overrides:

pkcs11SetParameter in class PKCS11Signature

Parameters:

parametersSpec - The KCS11SignatureParameterSpec that contains the PKCS#11 parameters.

Throws:

java.security.InvalidAlgorithmParameterException - If the parameters are of incorrect type.

getMechanism

protected iaik.pkcs.pkcs11.Mechanism getMechanism()

Get the mechanism of this signature object. This implementation returns a mechanism with CKM_RSA_PKCS_PSS as ID.

Specified by:

getMechanism in class ExternalHashSignature

Returns:

The mechanism this object uses for signing and verification.

Postconditions:

(result <> null)

getMessageDigestName

protected java.lang.String getMessageDigestName()

Returns the message digest's name that this object uses to hash the data. This is the JCA name.

Specified by:

getMessageDigestName in class ExternalHashSignature

Returns:

A message digest's JCA name.

Postconditions:

(result <> null)
