Set the Optional JWS Unprotected Header

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.SetUnprotectedHeader, which sets the optional unprotected header for a signature.

bool success = false;

Chilkat.Jws jws = new Chilkat.Jws();

//  Protected header specifying HMAC-SHA256.
Chilkat.JsonObject header = new Chilkat.JsonObject();
header.UpdateString("alg","HS256");

if (success == false) {
    Debug.WriteLine(jws.LastErrorText);
    return;
}

//  Set the optional unprotected header for signature 0.  Unlike the protected header, it is not
//  covered by the signature.  It is carried in the JSON serialization forms of a JWS.
Chilkat.JsonObject unprotected = new Chilkat.JsonObject();
unprotected.UpdateString("kid","signer-key-1");
success = jws.SetUnprotectedHeader(0,unprotected);
if (success == false) {

    Debug.WriteLine(jws.LastErrorText);

//  Because an unprotected header is present, the JWS is produced in a JSON serialization form.
