+ *   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.
