es.accv.arangi.base.device.util.pkcs11.SignatureEngine

public class SignatureEngine
extends java.security.Signature

This is an implementation of a JCA Signature class that uses the PKCS#11 wrapper to create the signature. This implementation hashes outside the token (i.e. in software) and support only signing but not verification.

SignatureEngine

public SignatureEngine(java.lang.String algorithmName,
               iaik.pkcs.pkcs11.Session session,
               iaik.pkcs.pkcs11.Mechanism signatureMechanism,
               java.security.MessageDigest md)
                throws java.security.NoSuchAlgorithmException

Creates a new signature engine that uses the given parameters to create the signature on the PKCS#11 token.

Parameters:

algorithmName - The name of the signature algorithm. This class does not interpret this name; it uses it as is.

session - The PKCS#11 session to use for signing. It must have the permissions to sign with the used private key; e.g. it may require a user session.

signatureMechanism - The PKCS#11 mechanism to use for signing; e.g. Mechanism.RSA_PKCS.

md - The hash

Throws:

java.security.NoSuchAlgorithmException - If the hash algorithm is not available.
