ARC4 PRNG (Pseudo Random Number Generator)

See more Encryption Examples

Uses the ARC4 stream encryption algorithm as a pseudo random number generator. 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();

  // Set the encryption algorithm to ARC4:	
  crypt.cryptAlgorithm = 'arc4';

  // We want the encrypted output to be a hex-encoded string.
  crypt.encodingMode = 'hex';

  final key = '000102030405060708090A0B0C0D0E0F';
  var data = '12345678';

  // Key length is 128 bits in this example.
  crypt.keyLength = 128;
  crypt.setEncodedKey(key, 'hex');

  // Generate 16 "random" 8-byte blocks, encoded as hex strings.
  // This example will generate the identical output each time
  // it is run.
  var cipherHex = '';
  for (var i = 0; i <= 15; i++) {
    cipherHex = crypt.encryptStringENC(data);
    print(data);
    print(cipherHex);
    data = cipherHex;
  }
