DBCrypt

Port of jBCrypt to Dart.

This system hashes passwords using a version of Bruce Schneier's Blowfish block cipher with modifications designed to raise the cost of off-line password cracking. The computation cost of the algorithm is parameterised, so it can be increased as computers and Dart VM get faster.

Installation

Add to your pubspec.yaml the following:

dependencies:
  dbcrypt: ^1.0.0

Usage

Hashing a password is easy:

import 'package:dbcrypt/dbcrypt.dart'

main() {
  var plainPassword = "P@55w0rd";
  var hashedPassword = new DBCrypt().hashpw(plainPassword, new DBCrypt().gensalt());
}

Comparing a plain and a hashed password is even easier:

var isCorrect = new DBCrypt().checkpw(plain, hashed);

Running Tests

Dependencies are installed using the Pub Package Manager.

# For running the tests it needs the 'dart' executable on your path. 
# Execute the next command if it isn't already on your path:
export DART_SDK=path/to/dart/sdk

pub install

test/run.sh

1.0.0

Upgrade to Dart 2
Add support for $2y$ and $2b$ versions of BCrypt
Password are now generated with $2b$ since this lib doesn't have the OpenBSD $2a$ version bug

0.2.0

Upgrade to Dart 1

example/example.dart

import 'package:dbcrypt/dbcrypt.dart';

void main() {
  DBCrypt dBCrypt = DBCrypt();
  const plainPwd = "mySuperSecretP@ssw0rd";
  // Hash password with default values
  String hashedPwd = dBCrypt.hashpw(plainPwd, dBCrypt.gensalt());

  // Check the plain password against the hashed password
  assert(dBCrypt.checkpw(plainPwd, hashedPwd), true);

  // Generate a salt with a cost of 12 and hash the password with it
  String salt = dBCrypt.gensaltWithRounds(12);
  hashedPwd = dBCrypt.hashpw(plainPwd, salt);

  // Check the plain password against the 12-cost hashed password
  assert(dBCrypt.checkpw(plainPwd, hashedPwd), true);
}
