Example (Basic):

Read and verify JWT:

use Krishna\JWT\JWT;

$secret_key = 'your-secret';

$jwt = new JWT('eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJ0b2tlbi50ZXN0LmNvbSIsImF1ZCI6ImFwcC50ZXN0LmNvbSIsImlhdCI6MTY0Mzg5MTc1OCwibmJmIjoxNjQzODkxNzU4LCJleHAiOjE2NzI1MzQ4MDAsIm5hbWUiOiJBbnNodSBLcmlzaG5hIiwiY2l0eSI6IkJhbmdhbG9yZSIsImp0aSI6IjZmZGZhY2JkLWU1N2MtNDI1Yy1hNDBmLWM3NjQ5YjBkNDg0MSJ9.U7o6m77GP3oX_A_DgjgkS6U9rSLspPkOL_1dQLkr6QM');

var_dump(['JWT' => $jwt]);

echo "<hr />";
var_dump(['Verify' => $jwt->verify($secret_key)]);

Output:

Create JWT:

use Krishna\JWT\Algo;
use Krishna\JWT\JWT;

$secret_key = 'your-secret';

$jwt = new JWT;

$jwt['name'] = 'AK';
$jwt['country'] = 'India';

$jwt->sign($secret_key, Algo::HS512);

echo "Token: ", $jwt, "<br><br>";

var_dump($jwt);

Output:
