HMAC with SHA256

See more Encryption Examples

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

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

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

// 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";

string mac;

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