Description:

This is small library that can be used to verify JSON Web Tokens. There are 2 classes that are
used in this library JsonWebToken and Verifier, the JsonWebToken class allows to segment the pieces
of the token out so they can be easily generated/derived.

To use the Verifier, all you will need is a JsonWebToken instance, as well as the key that was used to sign
token (in a lot of cases this will be your Client Secret).

Examples

Verifying a JWT

use Tokin\JWT\JsonWebToken;
use Tokin\JWT\Verifier;

$token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6IjEyMzM0NjQ2NCIsImZpcnN0X25hbWUiOiJUZXN0IiwibGFzdF9uYW1lIjoiTWNUZXN0ZXJzb24iLCJlbWFpbCI6InRlc3RAdGVzdC5jb20iLCJleHBpcmVzIjoxMjMyMTQyfQ.7BHgbsBAyK0IRDKPtFOhHKFYta6_fdujngX64zMYrtg';
$key = 'abcdefghijklmno';

$verifier = new Verifier();
$jwt = new JsonWebToken($token);

return $verifier->verify($jwt, $key); // returns a boolean

Retrieving Header Info From JWT

use Tokin\JWT\JsonWebToken;

$token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6IjEyMzM0NjQ2NCIsImZpcnN0X25hbWUiOiJUZXN0IiwibGFzdF9uYW1lIjoiTWNUZXN0ZXJzb24iLCJlbWFpbCI6InRlc3RAdGVzdC5jb20iLCJleHBpcmVzIjoxMjMyMTQyfQ.7BHgbsBAyK0IRDKPtFOhHKFYta6_fdujngX64zMYrtg';

$jwt = new JsonWebToken($token);

$headers = $jwt->getHeader(true); // this will return the JSON for the header, false will return the Base 64 URL Encoded value

// {"typ": "JWT", "alg":"HS256"}

Retrieving the Payload Info From JWT

use Tokin\JWT\JsonWebToken;

$token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6IjEyMzM0NjQ2NCIsImZpcnN0X25hbWUiOiJUZXN0IiwibGFzdF9uYW1lIjoiTWNUZXN0ZXJzb24iLCJlbWFpbCI6InRlc3RAdGVzdC5jb20iLCJleHBpcmVzIjoxMjMyMTQyfQ.7BHgbsBAyK0IRDKPtFOhHKFYta6_fdujngX64zMYrtg';

$jwt = new JsonWebToken($token);

$payload = $jwt->getPayload(true); // this will return the JSON for the header, false will return the Base 64 URL Encoded value

Retrieving the Signature From JWT

use Tokin\JWT\JsonWebToken;

$token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6IjEyMzM0NjQ2NCIsImZpcnN0X25hbWUiOiJUZXN0IiwibGFzdF9uYW1lIjoiTWNUZXN0ZXJzb24iLCJlbWFpbCI6InRlc3RAdGVzdC5jb20iLCJleHBpcmVzIjoxMjMyMTQyfQ.7BHgbsBAyK0IRDKPtFOhHKFYta6_fdujngX64zMYrtg';

$jwt = new JsonWebToken($token);

$signature = $jwt->getSignature();

Retrieving the Original JWT

use Tokin\JWT\JsonWebToken;

$token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6IjEyMzM0NjQ2NCIsImZpcnN0X25hbWUiOiJUZXN0IiwibGFzdF9uYW1lIjoiTWNUZXN0ZXJzb24iLCJlbWFpbCI6InRlc3RAdGVzdC5jb20iLCJleHBpcmVzIjoxMjMyMTQyfQ.7BHgbsBAyK0IRDKPtFOhHKFYta6_fdujngX64zMYrtg';

$jwt = new JsonWebToken($token);

$token = $jwt->getOriginalToken();
