Quick Start

Creating Signature

HMAC

use Gandung\JWT\JWTFactory;

$key = JWTFactory::getKeyManager();
$key->setPassphrase('secret');
$header = JWTFactory::getJoseBuilder()
	->algorithm(\Gandung\JWT\Token\Algorithm::HS256)
	->type('JWT')
	->contentType('application/json');
$claim = JWTFactory::getClaimBuilder()
	->issuedBy('me')
	->expireAt(new \DateTimeImmutable('@' . (time() + 3600)));
$payload = JWTFactory::getPayloadBuilder()
	->claim($claim)
	->userData([
		'credentials' => [
			'username' => 'me',
			'password' => 'this_is_me_who_want_to_get_in'
		]
	]);
$jwt = JWTFactory::getJwt();
$token = $jwt->createToken($header, $payload, $key);

echo sprintf("Token: %s\n", $token);

RSA

use Gandung\JWT\JWTFactory;

$key = JWTFactory::getKeyManager();
// See: cert/dummy256.pem (Private Key)
$key->setContentFromCertFile('cert/dummy256.pem');
$key->setPassphrase('umar123');
$header = JWTFactory::getJoseBuilder()
	->algorithm(\Gandung\JWT\Token\Algorithm::RS256)
	->type('JWT')
	->contentType('application/json');
$claim = JWTFactory::getClaimBuilder()
	->issuedBy('me')
	->expireAt(new \DateTimeImmutable('@' . (time() + 3600)));
$payload = JWTFactory::getPayloadBuilder()
	->claim($claim)
	->userData([
		'credentials' => [
			'username' => 'me',
			'password' => 'this_is_me_who_want_to_get_in'
		]
	]);
$jwt = JWTFactory::getJwt();
$token = $jwt->createToken($header, $payload, $key);

echo sprintf("Token: %s\n", $token);

ECDSA

use Gandung\JWT\JWTFactory;

$key = JWTFactory::getKeyManager();
// See: cert/secp256.pem (Elliptic-Curve Private Key)
$key->setContentFromCertFile('cert/secp256.pem');
$header = JWTFactory::getJoseBuilder()
	->algorithm(\Gandung\JWT\Token\Algorithm::ES256)
	->type('JWT')
	->contentType('application/json');
$claim = JWTFactory::getClaimBuilder()
	->issuedBy('me')
	->expireAt(new \DateTimeImmutable('@' . (time() + 3600)));
$payload = JWTFactory::getPayloadBuilder()
	->claim($claim)
	->userData([
		'credentials' => [
			'username' => 'me',
			'password' => 'this_is_me_who_want_to_get_in'
		]
	]);
$jwt = JWTFactory::getJwt();
$token = $jwt->createToken($header, $payload, $key);

echo sprintf("Token: %s\n", $token);
