Usage

Provide an array of key id strings mapped to hex-encoded keys to the constructor. Then you can encode() and decode() arrays containing arbitrary claims.

<?php
// Define your keys
$encoder = new WP_Paseto((
    'key-id-1' => 'hex-encoded 256-bit (32 byte) random key goes here',
    'key-id-2' => 'hex-encoded 256-bit (32 byte) random key goes here',
    // ...
    'key-id-N' =>L 'hex-encoded 256-bit (32 byte) random key goes here'
));

// Encode a secret
$token = $encoder->encode(array('secret' => 'value goes here'));

var_dump($token);
/* v4.local.fHvh8jwJauiNMdC0yRZ9xvbCE5cdrNwP4... */

// Decode
$claims = $encoder->decode($token);
