Sesshin
=======

[](#sesshin)

Object-oriented, extendable advanced session handling component written with security in mind that mitigates attacks like Session Hijacking, Session Fixation, Session Exposure, Sesion Poisoning, Session Prediction.

Awarded 1st place in [php.pl contest](http://wortal.php.pl/phppl/Wortal/Spolecznosc/Konkursy/Konkurs-Pozyteczne-i-praktyczne-biblioteki-Wyniki).

Features:

- smart session expiry control
- prevents session adoption, i.e. session ids generated only by the component are acceptable (strict model)
- sends cookie only when session really created
- session id rotation (anti session hijacking), based on time and/or number of requests
- configurable:
- unlike PHP native mechanism, you don't have to use cron or resource-consuming 100% garbage collecting probability to ensure sessions are removed exactly after specified time
- convention over configuration - possible to configure user-defined stores, listeners (observers), entropy callback and fingerprint generators, but all of them have defaults set out-of-the-box
- 100% independent from insecure native PHP session extension

Usage
-----

[](#usage)

### Installation

[](#installation)

```
composer require sobstel/sesshin

```

### Create new session

[](#create-new-session)

Only when `create()` called, session cookie is created (for native PHP session handler cookie is present all the time whether it's needed or not).

```
$session->create();
```

### Open existing session

[](#open-existing-session)

If session was not created earlier, session is not opened and `false` is returned.

```
$session->open();
```

If you want to create new session if it does not exist already, just pass `true`as argument. It will call `create()` transparently.

```
$session->open(true);
```

### Regenerate session id

[](#regenerate-session-id)

```
// auto-regenerate after specified time (secs)
$session->setIdTtl(300);

// auto-regenerate after specified number of requests
$session->setIdRequestsLimit(10);

// manually
$session->regenerateId();
```

### Listen to special events

[](#listen-to-special-events)

```
use Sesshin\Event\Event;

$eventEmitter = $session->geEmitter();

$eventEmitter->addListener('sesshin.no_data_or_expired', function(Event $event) {
  die('Session expired or session adoption attack!');
});
$eventEmitter->addListener('sesshin.expired', function(Event $event) {
  die(sprintf('Session %s expired!', $event->getSession()->getId()));
});
$eventEmitter->addListener('sesshin.invalid_fingerprint', function(Event $event) {
  die('Invalid fingerprint, possible attack!');
});
```

### User session

[](#user-session)

```
use Sesshin\User\Session as UserSession;
use Sesshin\Store\FileStore;

$userSession = new UserSession(new FileStore('/path/to/dir'));

$userSession->create();
$userSession->login(123);

if ($userSession->isLogged()) {
  echo sprintf('User %s is logged', $userSession->getUserId());

  // Or if you have some kind of UserRepository class, which can be used to fetch user data
  $user = UserRepository::find($userSession->getUserId());
  echo sprintf('User %s is logged', $user->getUsername());
}
```

### Store

[](#store)

Sesshin provides default FileStore.

```
use Sesshin\Session;
use Sesshin\Store\FileStore;

$session = new Session(new FileStore('/path/to/dir'));
```

Note! Using /tmp as a directory is not secure on shared hosting.

Alternatively you can use one of numerous [doctrine/cache](https://github.com/doctrine/cache/tree/master/lib/Doctrine/Common/Cache)providers.

```
use Sesshin\Store\DoctrineCache;
use Doctrine\Common\Cache\MemcachedCache;

$memcached = new Memcached;
// here configure memcached (add servers etc)

$session = new Session(new DoctrineCache(new MemcachedCache($memcached)));
```

You can also implement your own store using `Sesshin\Store\StoreInterface`.

### Change entropy algorithm

[](#change-entropy-algorithm)

Entropy is used to generate session id.

```
$session->getIdHandler()->setEntropyGenerator(new MyFancyEntropyGenerator());
```

`MyFancyEntropyGenerator` must implement `Sesshin\EntropyGenerator\EntropyGeneratorInterface`.

### Change session ID store

[](#change-session-id-store)

By default session ID is stored in cookie, but sometimes you may need to force session id, eg. based on some token, query string var, etc.

```
$session->getIdHandler()->setIdStore(new MyFancyIdStore());
```

`MyFancyIdStore` must implement `Sesshin\Id\Store\StoreInterface`.
