REST API's are meant to be stateless. What that means is that each request from a client should include all the information needed to process the request. In other words, if you are writing a REST API in PHP then you should not be using $_SESSION to store data about the client's session. But then how do we remember if a client is logged in or anything else about their state? The only possibility is that the client must be tasked with keeping track of the state. How could this ever be done securely? The client can't be trusted!

MultiOTP PHP class: Authenticate and manage OTP strong user tokens. This class can be used to authenticate and manage OTP user tokens for strong two-factor authentication. It can create, update and delete tokens to authenticate users with one time passwords (OTP). The users data is stored in files. The class should have method generate, that would generate a key and isValid method, to check if the key is valid. Php security key generator api-key share improve this question follow.

Enter JSON web tokens. A JSON web token is a bit of JSON, perhaps something that looks like this:

Of course, we can't just give this to a client and have them give it back to us without some sort of assurance that it hasn't been tampered with. After all, what if they edit the token as follows:

The solution to this is that JSON web tokens are signed by the server. If the client tampers with the data then the token's signature will no longer match and an error can be raised. Crypto key generate rsa 1024 command. A raid controller driver which is required if sata raid is enabled in bios.

The JWT PHP class makes this easy to do. For example, to create a token after the client successfully logs in, the following code could be used:

And then on later API calls the token can be retrieved and verified by this code:

If the token has been tampered with then $token will be empty there will not be an id available. The JWT class makes sure that invalid data is never made available. If the token is tampered with, it will be unusable. Pretty simple stuff!

You can get the PHP JWT class as a single file from: https://github.com/rmcdaniel/angular-codeigniter-seed/blob/master/api/application/helpers/jwt_helper.php

as it is used by the AngularJS CodeIgniter Seed project:
