All Implemented Interfaces:

PKCS11EngineClass

public class InternalSha256RsaSignature
extends PKCS11Signature

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_SHA256_RSA_PKCS mechanism to create the signature; i.e. it creates the hash on the token, if the PKCS#11 module itself is implemented in such a way and the token can do the hashing.

Method Detail

getAlgorithmName

protected java.lang.String getAlgorithmName()

Get the JCA standard name of this signautre algorithm.

Specified by:

getAlgorithmName in class PKCS11Signature

Returns:
