How to create hashes (message digests) for strings. Dart

import 'package:chilkat/chilkat.dart';

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

  final crypt = CkCrypt2();

  final s = 'The quick brown fox jumps over the lazy dog';

  crypt.hashAlgorithm = 'sha1';
  crypt.encodingMode = 'hex';

  // Other possible EncodingMode settings are: 
  // "quoted-printable", "base64","url", and many more..

  var hash = crypt.hashStringENC(s);
  print('SHA1: $hash');

  // Hash using MD2
  crypt.hashAlgorithm = 'md2';
  hash = crypt.hashStringENC(s);
  print('MD2: $hash');

  // Hash using MD5
  crypt.hashAlgorithm = 'md5';
  hash = crypt.hashStringENC(s);
  print('MD5: $hash');

  // Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512)

  // Hash using SHA-256
  crypt.hashAlgorithm = 'sha256';
  hash = crypt.hashStringENC(s);
  print('SHA256: $hash');

  // Hash using SHA-384
  crypt.hashAlgorithm = 'sha384';
  hash = crypt.hashStringENC(s);
  print('SHA384: $hash');

  // Hash using SHA-512
  crypt.hashAlgorithm = 'sha512';
  hash = crypt.hashStringENC(s);
  print('SHA512: $hash');

  // Hash using HAVAL
  // There are two additional properties relevant to HAVAL:
  // HavalRounds, and KeyLength.
  // HavalRounds can have values of 3, 4, or 5.
  // KeyLength can have values of 128, 160, 192, 224, or 256
  crypt.hashAlgorithm = 'haval';
  crypt.havalRounds = 5;
  crypt.keyLength = 256;
  hash = crypt.hashStringENC(s);
  print('Haval: $hash');
