Description:

blowfish

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");
}
