rc4 0.1.1

Implementation of RC4-Drop algorithm.

Intro

RC4 symmetric (drop frame) implementation base on previous work for BitFlip Games. Used when you need a simple but de/encryption that doesn't need the rigors of public key encryption.

Sample

const String key = "This is a test"; const String message = "Attack at dawn!";

test('General Setup',(){
  RC4 rc4 = new RC4(key);
  var encrypted = rc4.encode(message);
  var decrypted = rc4.decode(encrypted);
  expect(encrypted,"TVwO6ouZIc8d2FjL5lf8");
  expect(decrypted,message);
});
