Getting started

The following import will give you access to all of the algorithms in this package.

import 'package:cipherlib/cipherlib.dart';

Check the API Reference for details.

Usage

Examples can be found inside the example folder.

import 'package:cipherlib/cipherlib.dart';
import 'package:cipherlib/cipherlib.dart';

void main() {
  var key = [0x54];
  var inp = [0x03, 0xF1];
  print('text: ${toBinary(inp)}');
  print(' key: ${toBinary(key)}');
  print(' XOR: ${toBinary(xor(inp, key))}');
}
