Set the JWS Payload from BinData

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.SetPayloadBd, which sets the payload to be signed from the binary bytes in a BinData.

Background. JWS (JSON Web Signature) integrity-protects a payload with a signature or MAC. The header alg names the algorithm; this example uses HMAC-SHA256 (HS256) with a symmetric MAC key.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

var jws = new CkJws();

//  Set the payload from the binary bytes in a BinData.
var bdPayload = new CkBinData();
bdPayload.AppendString("Binary content to sign.","utf-8");

success = jws.SetPayloadBd(bdPayload);
if (success == false) {
    console.log(jws.LastErrorText);
    return;
}

console.log("Payload set.");
