A simple library to encode and decode JSON Web Tokens (JWT) in PHP. Should conform to the current spec
Use composer to manage your dependencies and download PHP-JWT:
composer require firebase/php-jwt<?php
$key = "example_key";
$token = array(
"iss" => "http://example.org",
"aud" => "http://example.com",
"iat" => 1356999524,
"nbf" => 1357000000
);
/**
* IMPORTANT:
* You must specify supported algorithms for your application. See
* https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
* for a list of spec-compliant algorithms.
*/
$jwt = JWT::encode($token, $key);
$decoded = JWT::decode($jwt, $key, array('HS256'));
print_r($decoded);
/*
NOTE: This will now be an object instead of an associative array. To get
an associative array, you will need to cast it as such:
*/
$decoded_array = (array) $decoded;
/**
* You can add a leeway to account for when there is a clock skew times between
* the signing and verifying servers. It is recomended this leeway should not
* be bigger than a few minutes.
* Source: http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#nbfDef
*/
JWT::$leeway = 60;
$decoded = JWT::decode($jwt, $key, array('HS256'));
?>- Note: It is strongly recommended that you update to > v2.0.0 to address known security vulnerabilities in prior versions when both symmetric and asymmetric keys are used together.
- Update signature for
JWT::decode(...)to require an array of supported algorithms to use when verifying token signatures.
Run the tests using phpunit:
