It's a quick and simple solution for developers who want to apply any level of security to their applications and they are not interested in learning to use available libraries.
DummyCastle should be used wherever there is a need to protect information that is not essential. For example, to protect:
- API keys
- chats
- messages
- settings
- generally small amount of data
DummyCastle should not be used whenever there is a need to secure high-value information. For example, to protect:
- money - ecoins
- secret information
- illegal information
- generally large amounts of data
The library provides the following features:
- symmetric encryption
- asymmetric encryption
- random generation
- hashing(digesting)
- shuffling
- obfuscation
One simple object is enough to handle all the operations and methods.
import 'package:dummycastle/pl/polinc/dummycastle/dummycastle.dart';
...
DummyCastle dummyCastle = new DummyCastle();
...
String password="Password";
dummyCastle.genSymmKeyWith(password);
String encrypted = dummyCastle.encryptSymmWith(plainText).getResult();//Symmetric encryption
String encrypted = dummyCastle.encryptSymmWith(plainText).getResult();
String decrypted = dummyCastle.decryptSymmWith(encrypted).getResult();
String decodedResult = dummyCastle.decodeWith(decrypted).toStringDecoded();//Asymmetric encryption
CryptAsymmKeysPair cryptAsymmKeysPair = dummyCastle.genAsymmKeys();
CryptAsymmPublicKey cryptAsymmPublicKey = cryptAsymmKeysPair.getCryptAsymmPublicKey();
CryptAsymmPrivateKey cryptAsymmPrivateKey = cryptAsymmKeysPair.getCryptAsymmPrivateKey();
String encrypted = dummyCastle.encryptAsymmWith(plainText, cryptAsymmPublicKey).getResult();
String decrypted = dummyCastle.decryptAsymmWith( encrypted , cryptAsymmPrivateKey).getResult();
String decodedResult=dummyCastle.decodeWith(decrypted).toStringDecoded();//Random generation
String randomInt1 = dummyCastle.randomNumWith(8).getResultDecoded();
String randomStr1 = dummyCastle.randomStrWith(8).getResultDecoded();
String randomInt2 = dummyCastle.randomDeterministicNumWith(someRand1, 8).getResult();//Hashing
String hashed1 = dummyCastle.hashToNumWith(plainText1).getResult();
String hashed2 = dummyCastle.hashToStrWith(plainText1).getResult();//Shuffling
String someRand1="aAbBcC";
String shuffled1 = dummyCastle.shuffleWith(plainText).getResultDecoded();
String shuffled2 = dummyCastle.shuffleDeterministicWith(plainText, someRand1).getResultDecoded();//Obfuscation
String obfuscated = dummyCastle.obfuscateWith(plainText).getResult();
String unobfuscated = dummyCastle.unobfuscateWith(obfuscated).getResult();//Clean up - optional
dummyCastle.reset();This library is an official port fo Java version which can be found here: https://github.com/polincdev/DummyCastle
The Dart/FLutter version is available here: https://github.com/polincdev/DummyCastle4Dart
The versions remain synced.
