Set the JWS Payload

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.SetPayload, which sets the content to be signed. The charset converts the text to bytes, and a flag controls whether a byte-order mark is included.

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 (the content to be signed).  The 2nd argument is the charset used to convert the
//  text to bytes, and the 3rd controls whether a byte-order mark is included.
var bIncludeBom = false;
success = jws.SetPayload("This is the content to sign.","utf-8",bIncludeBom);
if (success == false) {
    console.log(jws.LastErrorText);
    return;
}

console.log("Payload set.");
