I have an API that leverages the REST controller. How I have it set now is basically I generate a sha256 hash and use that as a session key which is sent with each request. I was wondering if anyone has tried to use the session class to generate keys for API requests.
For generating keys, FuelPHP uses PHPSecLib, which is included in the core/vendor directory. Check the crypt class or the Auth package to see how it is used.
API session storage is not possible at the moment, but sounds like an interesting addition. Could you add this as a feature request on http://github.com/fuel/core/issues, and include the use-case?
