/*
 * 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
 *   (unless you've enabled FIPS). It supports Public Key ops, and all they
 *   bulk ciphers and hashes. It can also support Private Key ops for imported
 *   Private keys. It does not have any token storage.
 *	slot 2 is our private key support. It requires a login before use. It
 *   can store Private Keys and Certs as token objects. Currently only private
 *   keys and their associated Certificates are saved on the token.
 *
 *   In this implementation, session objects are only visible to the session
 *   that created or generated them.
