Set the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetProtectedHeader, which sets the integrity-protected JWE header from a JsonObject. The header specifies the key-management algorithm (alg) and content-encryption algorithm (enc).

<?php

use Chilkat2\JsonObject;
use Chilkat2\Jwe;

$jwe = new Jwe();

// Build the JWE protected header.  The "alg" member names the key-management algorithm and the "enc"
// member names the content-encryption algorithm.
$header = new JsonObject();
$header->UpdateString('alg', 'A256KW');
$header->UpdateString('enc', 'A256GCM');

// Set the protected header on the JWE.  The protected header is integrity-protected and applies to
// all recipients.
try {
    $jwe->SetProtectedHeader($header);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo "Protected header set.\n";
