See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.GetPayloadSb, which writes the payload of a loaded JWS as text into a StringBuilder, decoded using the given charset.

Background. In practice, validate the signature before trusting the payload.

var success = false;

//  Load the JWS compact serialization.
var jwsCompact = "eyJhbGciOiJIUzI1NiJ9.VGhpcyBpcyB0aGUgY29udGVudCB0byBzaWduLg.<signature>";
success = jws.LoadJws(jwsCompact);
if (success == false) {
    console.log(jws.LastErrorText);
    return;

//  Get the JWS payload as text into a StringBuilder, decoded using the given charset.
