README

A custom JWT Wrapper to be used in iMemento projects. It uses the RS256 algorithm and it is framework independent.

Install

composer require imemento/jwt

Usage

use iMemento\JWT\JWT;

Encoding

To encode a JWT just use the encode static method:

/**
 * $payload object/array
 * $privateKey mixed the key used to sign the token
 */
$token = JWT::encode($payload, $private_key);

Decoding

To decode a JWT we must follow the next steps.

1. Instantiate the class with the token we want to decode:

   $jwt = new JWT($token);

2. Get the issuer before checking the signature (used to find the correct public key):

   $issuer = $jwt->getIssuer();

3. Get the payload and check the signature at the same time:

   $payload = $jwt->decode($public_key);

Additional Classes

Guard.php - Decrypts the token and is used to extract the permissions from it.

Issuer.php - Represents the current application.

Payload.php - Is used to create a standard payload for the JWT.
