HMAC with SHA256

Demonstrates how to compute a HMAC SHA256 keyed-hash message authentication code.

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

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

var crypt = new CkCrypt2();

// The output will be Hex, so set the EncodingMode:
crypt.EncodingMode = "hex";

// Set the hash algorithm:
// Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
crypt.HashAlgorithm = "sha256";
crypt.MacAlgorithm = "hmac";

var mac;

// Set the HMAC key:
crypt.SetMacKeyEncoded("The_API_Secret","ascii");
mac = crypt.MacStringENC("The quick brown fox jumps over the lazy dog");
console.log(mac);
