+ * 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
