Title:
  keystone token cache should offer encryption like the middleware cache
  does

Status in OpenStack Identity (keystone):
  Triaged

Bug description:
  Keystone middleware's caching of tokens offers HMAC validation and
  encryption of the tokens in the cache. This is important because
  memcache has literally zero authentication or protection from any user
  on the system.  So this feature should be ported in from keystone
  middleware into keystone.
