Example: Crypt2.GenRandomBytesENC method

Shows how to use the GenRandomBytesENC method to generate a specified number of random bytes and return them as a binary encoded string, such as in base64 or hex format. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final crypt = CkCrypt2();

  // Example of a some of the binary encodings supported by Chilkat.

  // Internally uses the Fortuna cryptographically secure random number generation algorithm
  // auto-seeded from a secure source of entropy that depends on the OS.

  crypt.encodingMode = 'hex';
  var s = crypt.genRandomBytesENC(8);
  print('Uppercase Hex: $s');

  crypt.encodingMode = 'hex_lower';
  s = crypt.genRandomBytesENC(8);
  print('Lowercase Hex: $s');

  crypt.encodingMode = 'base64';
  s = crypt.genRandomBytesENC(8);
  print('Base64: $s');

  crypt.encodingMode = 'base64url';
  s = crypt.genRandomBytesENC(8);
  print('Base64Url: $s');

  crypt.encodingMode = 'base58';
  s = crypt.genRandomBytesENC(8);
  print('Base58: $s');

  crypt.encodingMode = 'base32';
  s = crypt.genRandomBytesENC(8);
  print('Base32: $s');

  crypt.encodingMode = 'decList';
  s = crypt.genRandomBytesENC(8);
  print('Decimal List: $s');

  // Sample Output:

  // Uppercase Hex: 1BA0E87915C3B429
  // Lowercase Hex: 1e1638a1c7996c58
  // Base64: 1lV0I/su5lg=
  // Base64Url: Zq7DU0nukLk
  // Base58: foUVWUjAT6e
  // Base32: LHV5RV4HRCLW2===
  // Decimal List: 168,55,214,82,93,154,191,164
