Salt, a crypto library for Flutter #

Build Status Coverage Status License

This is a simple and pure Dart library which adds support for cryptography in Flutter apps without having to use native C bindings. The goal for this project is to slowly adopt several crypto algorithms with proper tests.

Currently the following crypto algorithms are supported:

  • chacha20-poly1305

Getting started #

First of all add the following dependencies to your pubspec.yaml:

  salt: ^0.1.1

Then you will find everything you need in the Salt class. Below is an example how to encrypt and decrypt a message using chacha20-poly1305:

import 'package:salt/binhex.dart';
import 'package:salt/salt.dart'

var key = BinHex.hex2bin('4290bcb154173531f314af57f3be3b5006da371ece272afa1b5dbdd1100a1007');
var input = BinHex.hex2bin('86d09974840bded2a5ca');
var nonce = BinHex.hex2bin('cd7cf67be39c794a');
var ad = BinHex.hex2bin('87e229d4500845a079c0');

var ciphertext = Salt.chacha20Poly1305Encrypt(input, ad, nonce, key);
var plaintext = Salt.chacha20Poly1305Decrypt(ciphertext, ad, nonce, key);

Notes #

  • This library uses a lot of ported code from the following repository:
  • In this library we use List<int> instead of Uint8List

[0.1.2] - 15-07-2019 #
