* 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.
* 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.
