// Demonstrates how to create a JWT using an certificate's private key.

$cert = new Cert();

// Load an ECC private key from a PEM file.
try {

// Build the JOSE header
$jose = new JsonObject();
// Note: The IsEcdsa function was added in Chilkat v10.1.0
if ($cert->IsEcdsa()) {
    // Use ES256.  Pass the string "ES384" or "ES512" to use ECC with SHA-384 or SHA-512.
    $jose->AppendString('alg', 'ES256');
} else {
    // Probably RSA...
    // Use RS256.  Pass the string "RS384" or "RS512" to use RSA with SHA-384 or SHA-512.
    $jose->AppendString('alg', 'RS256');
}

$jose->AppendString('typ', 'JWT');

// Now build the JWT claims (also known as the payload)
$claims = new JsonObject();
$claims->AppendString('iss', 'http://example.org');
$claims->AppendString('sub', 'John');
$claims->AppendString('aud', 'http://example.com');

// Set the timestamp of when the JWT was created to now.
$curDateTime = $jwt->GenNumericDate(0);
$claims->AddIntAt(-1, 'iat', $curDateTime);

// Set the "not process before" timestamp to now.
$claims->AddIntAt(-1, 'nbf', $curDateTime);

// Set the timestamp defining an expiration time (end time) for the token
// to be now + 1 hour (3600 seconds)
$claims->AddIntAt(-1, 'exp', $curDateTime + 3600);

// Produce the smallest possible JWT:
$jwt->AutoCompact = true;

// Create the JWT token.
$token = $jwt->CreateJwtCert($jose->Emit(), $claims->Emit(), $cert);

echo $token, "\n";
