PasswordHashingMachine
======================

[![Build Status](https://camo.githubusercontent.com/74e6c929ea229fc6e382f6f0b699402943949e846d715579feb18d712c036d93/68747470733a2f2f6170702e7472617669732d63692e636f6d2f79617272692f50617373776f726448617368696e674d616368696e652e7376673f6272616e63683d6d6173746572)](https://app.travis-ci.com/yarri/PasswordHashingMachine)

PasswordHashingMachine is tool for hashing and checking passwords using a required hashing algorithm, which must be registered from the outside.

More hashing algorithms can be registered to PasswordHashingMachine so legacy hashes can be also successfully handled.

Usage
-----

[](#usage)

### 1. Create the hashing machine

[](#1-create-the-hashing-machine)

```
$hasher = new Yarri\PasswordHashingMachine();

```

### 2. Add one or more hashing algorithms

[](#2-add-one-or-more-hashing-algorithms)

```
//  $hasher->addAlgorithm(
//    callback $hash_callback,
//    callback $is_hash_callback,
//    callback $check_password_callback
//  );

```

The first added algorithm is also the default hashing algorithm.

```
// default hashing algorithm - bcrypt
$hasher->addAlgorithm(
  function($password){ return password_hash($password,PASSWORD_BCRYPT); },
  function($password){ return !password_needs_rehash($password,PASSWORD_BCRYPT); },
  function($password,$hash){ return password_verify($password,$hash); }
);

```

Add another legacy hashing algorithms you need in your application.

```
// algorithm for md5 hashes with common salt
$hasher->addAlgorithm(
  function($password){ return md5(SITE_KEY.$password); },
  function($password){ return preg_match('/^[0-9a-f]{32}$/',$password); },
  function($password,$hash){ return md5(SITE_KEY.$password) === $hash; }
);

// algorithm for md5 hashes
$hasher->addAlgorithm(
  function($password){ return md5($password); },
  function($password){ return preg_match('/^[0-9a-f]{32}$/',$password); },
  function($password,$hash){ return md5($password) === $hash; }
);

```

In fact, for algorithms that provides hexadecimal hashes like md5, sha1, sha2, only the first callback is required.

```
$hasher->addAlgorithm(
  function($password){ return sha1($password); }
);

```

### 3. Use the machine

[](#3-use-the-machine)

```
// hashing passwords
$hasher->hash("secret"); // e.g. '$2a$06$rLxnps2CuGC/9BPCq3ms..7uaWETN6GPiVMXYYGWqdQoMZsDQ/kFG'
$hasher->hash('$2a$06$rLxnps2CuGC/9BPCq3ms..7uaWETN6GPiVMXYYGWqdQoMZsDQ/kFG'); // rehash! e.g. '$2y$10$XPuxlYvtelPKTpYtBpeAxOEuidftLo/kGkmmZgtWCFehvWz2N43wy'
$hasher->hash(""); // e.g. '$2y$10$FZQFYFamZjnrUr1XvIdGTevA.iLQNSYvHXrP3LETn67AEGreuYCwe'

// hashing password but preserving valid hashes or empty parameters
$hasher->filter("secret"); // e.g. '$2a$06$rLxnps2CuGC/9BPCq3ms..7uaWETN6GPiVMXYYGWqdQoMZsDQ/kFG'
$hasher->filter('$2a$06$rLxnps2CuGC/9BPCq3ms..7uaWETN6GPiVMXYYGWqdQoMZsDQ/kFG'); // '$2a$06$rLxnps2CuGC/9BPCq3ms..7uaWETN6GPiVMXYYGWqdQoMZsDQ/kFG'
$hasher->filter(""); // ""
$hasher->filter(null); // null

// checking hashes
$hasher->isHash($hash); // true
$hasher->isHash("something"); // false
$hasher->isHash(""); // false

// verifying passwords
$hasher->verify($password,$hash); // true or false

```

After a successful verification, the legacy hash can be detected and the password re-hashing using the current hashing algorithm can be easily realized.

```
$hash = $user->getPasswordHash();
if($hasher->verify($password,$hash,$is_legacy_hash)){
  // the user is verified
  if($is_legacy_hash){
     // transparent password re-hashing using the current hashing algorithm
     $current_hash = $hasher->hash($password);
     $user->setPasswordHash($current_hash);
  }
}

```
