+=item C<disable_simple_cram>
+
+Disables simple cram type from being an available type. Default is
+false. If set, then one of use_plaintext, use_crypt, or
+secure_hash_keys should be set. Setting this option allows for
+payloads to be generated by the server only - otherwise a user who
+understands the algorithm could generate a valid simple_cram cookie
+with a custom payload.
+
+Another option would be to only accept payloads from tokens if use_blowfish
+is set and armor was equal to "blowfish."
