PHP JSON Web Token (JWT) Library

JSON Web Token (JWT) implementation based on draft-ietf-oauth-json-web-token-25.

Installation

The recommended way to install gamegos/jws is through Composer.

{ "require": { "gamegos/jwt": "~0.1" } }

Basic Usage

Encoding

$key = 'some-secret-for-hmac'; $alg = 'HS256'; $token = new \Gamegos\JWT\Token(); $token->setClaim('sub', 'someone@example.com'); // alternatively you can use $token->setSubject('someone@example.com') method $token->setClaim('exp', time() + 60*5); $encoder = new \Gamegos\JWT\Encoder(); $encoder->encode($token, $key, $alg); printf("JWT TOKEN: %s\n", $token->getJWT()); //eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJzb21lb25lQGV4YW1wbGUuY29tIiwiZXhwIjoxNDA4NDUzNzkwfQ.2Fk5-UUMhOAcQH812LL0sdaf29zuf293nLhHp_VKBDg

Validation

$jwtString = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJzb21lb25lQGV4YW1wbGUuY29tIiwiZXhwIjoxNDA4NDUyMzcxfQ.Fy1DLdfZBiR_khyTsghItDW3_1rM7osz_IxjiaiRto0'; $key = 'some-secret-for-hmac'; try { $validator = new \Gamegos\JWT\Validator(); $token = $validator->validate($jwtString, $key); print_r($token->getClaims()); print_r($token->getHeaders()); } catch (\Gamegos\JWT\Exception\JWTException $e) { printf("Invalid Token:\n %s\n", $e->getMessage()); //$e->getToken(); }

See examples folder for sample code.

Supported Signature Algorithms

This package uses gamegos/jws for signing tokens. Currently supported signature and mac algorithms:

  • HS256, HS384, HS512 (HMAC using SHA-XXX)
  • RS256, RS384, RS512 (RSASSA-PKCS-v1_5 using SHA-XXX)
