Blowfish encryption algorithm implementation in Dart with both ECB and CBC modes.

Blowfish

Blowfish encryption algorithm implementation in Dart with both ECB and CBC modes.

Usage

The following simple usage is adapted from the included example project:

import 'dart:convert';
import 'package:blowfish/blowfish.dart';

void main() {
  // Example key 
  List<int> key = utf8.encode("mysecretpassword");

  // Plaintext
  String plaintext = "testtext";
  List<int> plaintextBytes = utf8.encode(plaintext);

  print("Plaintext: $plaintextBytes");

  // Create a Blowfish instance
  Blowfish blowfish = newBlowfish(key);

  // Encrypt
  List<int> encrypted = blowfish.encryptECB(plaintextBytes);
  print("Encrypted ECB: $encrypted");

  // Decrypt
  List<int> decrypted = blowfish.decryptECB(encrypted);

  print("Decrypted ECB: $decrypted");

  // Encrypt with CBC
  encrypted = blowfish.encryptCBC(plaintextBytes, utf8.encode("12345678"));
  print("Encrypted CBC: $encrypted");

  // Decrypt with CBC
  decrypted = blowfish.decryptCBC(encrypted, utf8.encode("12345678"));
  print("Decrypted CBC: $decrypted");

  // newSaltedBlowfish
  Blowfish saltedBlowfish = newSaltedBlowfish(key, utf8.encode("12345678"));
  encrypted = saltedBlowfish.encryptECB(plaintextBytes);
  print("Encrypted Salted: $encrypted");

  decrypted = saltedBlowfish.decryptECB(encrypted);
  print("Decrypted Salted: $decrypted");
}
