Base64url Encoding

Base64url encoding is identical to base64 encoding except it uses non-reserved URL characters (e.g. '–' is used instead of '+', and '_' is used instead of '/') and it omits the padding characters.

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;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var pkey = new CkPrivateKey();
var rsa = new CkRsa();
rsa.GenKey(1024,pkey);
rsa.UsePrivateKey(pkey);

var strData = "This is the string to be signed.";

// Get the signature in base64url
rsa.EncodingMode = "base64url";
var strSig = rsa.SignStringENC(strData,"sha256");

console.log(strSig);
