All Implemented Interfaces:

PKCS11EngineClass

public class RsaPkcs1Signature
extends PKCS11BufferingSignature

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 RSA_PKCS mechanism to create the signature. The application must provide a hash value as input. Refer to the PKCS#11 v2.11 standard for details.
