README

Hashapass is a library that generates unique and secure passwords, which are a hashed combination of a master password and a variable parameter.

The algorithm is based on a Base64 encode of the HMAC_SHA1 of the provided master password and parameter values.

Simple Usage

use Aalaap\Hashapass\Hashapass;

$hashapass = new Hashapass();
echo $hashapass->generate('master', 'parameter');

Motivation

I use Hashapass extensively to generate unique passwords for all my accounts. I need it at different places, so I've made a JavaScript bookmarklet, a Windows app and, now, a PHP package.

Installation

Install using Composer.

composer require aalaap/Hashapass

Advanced Usage

The package has one main method:

$hashapass->generate($master_password, $parameter);

By default, it will return a Hashapass-compatible 8-character password. To get a more secure 16-character password (or longer), simply specify the length:

$hashapass->generate($master_password, $parameter, 16);

Note that the maximum possible length is 40, as the algoritm is limited to the length of the generated HMAC_SHA1.

Tests

Hashapass has been tested in PHP 5.4 through PHP 7 and HHVM. If you want to run the tests, run:

vendor/bin/phpunit
