argon2

Pure Dart Argon2 algorithm (the winner of the Password Hash Competition 2015) for all Dart platforms (JS/Web, Flutter, VM/Native).

Based on the results of:

• https://password-hashing.net/
• https://www.ietf.org/archive/id/draft-irtf-cfrg-argon2-03.txt

Converted to Dart from:

• https://github.com/bcgit/bc-java/blob/master/core/src/main/java/org/bouncycastle/crypto/generators/Argon2BytesGenerator.java
• License: MIT

Usage

import 'dart:typed_data';

import 'package:argon2/argon2.dart';

void main() {
  var password = 'pass123456';
  var salt = 'somesalt'.toBytesLatin1();

  var parameters = Argon2Parameters(
    Argon2Parameters.ARGON2_i,
    salt,
    version: Argon2Parameters.ARGON2_VERSION_10,
    iterations: 2,
    memoryPowerOf2: 16,
  );

  print('Parameters: $parameters');

  var argon2 = Argon2BytesGenerator();

  argon2.init(parameters);

  var passwordBytes = parameters.converter.convert(password);

  print('Generating key from password...');

  var result = Uint8List(32);
  argon2.generateBytes(passwordBytes, result, 0, result.length);

  var resultHex = result.toHexString();

  print('Result: $resultHex');
}

Output:

Parameters: Argon2Parameters{ type: 1, iterations: 2, memory: 65536, lanes: 1, version: 16, converter: UTF8 }
Generating key from password...
Result: 297f7d074e07aaa46316ea006c1440dfe5707746426ec1df6c1d303ab5fd5533
