HMAC with SHA256

See more Encryption Examples

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

import 'package:chilkat/chilkat.dart';

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

  final crypt = 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';

  // Set the HMAC key:
  crypt.setMacKeyEncoded('The_API_Secret', 'ascii');
  final mac = crypt.macStringENC('The quick brown fox jumps over the lazy dog');
  print(mac);
