  * This file implements PKCS 11 on top of our existing security modules
  *
  * For more information about PKCS 11 See PKCS 11 Token Inteface Standard.
  *   This implementation has two slots:
  *      slot 1 is our generic crypto support. It does not require login.
  *   It supports Public Key ops, and all they bulk ciphers and hashes.
