Encrypt a JWE with a Password (PBES2)

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPassword, which sets the PBES2 password for a recipient. The example uses PBES2-HS256+A128KW key management with AES-128-GCM content encryption.

use chilkat();

$success = 0;

$jwe = chilkat::CkJwe->new();

#  Protected header: PBES2 password-based key management with AES-128-GCM content encryption.
$header = chilkat::CkJsonObject->new();
$header->UpdateString("alg","PBES2-HS256+A128KW");
$header->UpdateString("enc","A128GCM");
$success = $jwe->SetProtectedHeader($header);
if ($success == 0) {
    print $jwe->lastErrorText() . "\r\n";
    exit;
}

#  Set the PBES2 password for recipient 0.  The password should come from a secure source rather than
#  being hard-coded.
$password = "myPassword";
$success = $jwe->SetPassword(0,$password);
if ($success == 0) {
    print $jwe->lastErrorText() . "\r\n";
    exit;
}

$jweCompact = $jwe->encrypt("This is the secret content.","utf-8");
if ($jwe->get_LastMethodSuccess() == 0) {
    print $jwe->lastErrorText() . "\r\n";
    exit;
}

print $jweCompact . "\r\n";
