Set the JWS Protected Header

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.SetProtectedHeader, which sets the integrity-protected header for a signer from a JsonObject. The header specifies the signature algorithm (alg).

use chilkat();

$success = 0;

$jws = chilkat::CkJws->new();

#  Build the JWS protected header.  The "alg" member names the signature algorithm.
$header = chilkat::CkJsonObject->new();
$header->UpdateString("alg","HS256");

#  Set the protected header for signer index 0.  The protected header is integrity-protected: it is
#  covered by the signature.
$success = $jws->SetProtectedHeader(0,$header);
if ($success == 0) {
    print $jws->lastErrorText() . "\r\n";
    exit;
}

print "Protected header set." . "\r\n";
