Laravel Hashid provides a unified API across various drivers such as Base62, Base64, Hashids and Optimus, with support for multiple connections or different encoding options. It offers a simple, elegant way to obfuscate your data by generating reversible, non-sequential, URL-safe identifiers.

Installation

You can install this package using the Composer manager:

$ composer require elfsundae/laravel-hashid

For Lumen or earlier Laravel than v5.5, you need to register the service provider manually:

ElfSundae\Laravel\Hashid\HashidServiceProvider::class

Then publish the configuration file:

# For Laravel application:
$ php artisan vendor:publish --tag=hashid

# For Lumen application:
$ cp vendor/elfsundae/laravel-hashid/config/hashid.php config/hashid.php

Configuration

Our well documented configuration file is extremely similar to the configurations of numerous Laravel manager integrations such as Database, Queue, Cache and Filesystem. So you do not need to spend extra time to learn how to configure Hashid.

Additionally, for simplicity you do not need to add singleton drivers like Base64 to your config file as they have no encoding options, unless you would like to specify a meaningful connection name.

Let's see an example of the configuration:

'default' => 'id',

'connections' => [

    'basic' => [
        'driver' => 'base64',
    ],

    'hashids' => [
        'driver' => 'hashids',
        'salt' => 'sweet girl',
    ],

    'id' => [
        'driver' => 'hashids_integer',
        'salt' => 'My Application',
        'min_length' => 6,
        'alphabet' => '1234567890abcdef',
    ],

    'base62' => [
        'driver' => 'base62',
        'characters' => 'f9FkqDbzmn0QRru7PBVeGl5pU28LgIvYwSydK41sCO3htaicjZoWAJNxH6EMTX',
    ],

],

Usage

The hashid() helper or the Hashid facade may be used to interact with any of your configured connections or drivers:

use ElfSundae\Laravel\Hashid\Facades\Hashid;

// Obtain the default connection instance
hashid();
Hashid::connection();

// Obtain the "base62" connection instance
hashid('base62');
Hashid::connection('base62');

// Obtain the Base64 driver instance
hashid('base64');
Hashid::connection('base64');
Hashid::driver('base64');

There are only two methods you need to know to use any connection or driver:

  • encode($data) for encoding data.
  • decode($data) for decoding data.
hashid()->encode(123456);

hashid('base64')->decode('TGFyYXZlbA');

Hashid::encode(123456);

Hashid::connection('hashids')->decode('X68fkp');

And there are also two corresponding helper functions:

  • hashid_encode($data, $name = null)
  • hashid_decode($data, $name = null)
hashid_encode(123456);

hashid_decode('TGFyYXZlbA', 'base64');

Built-in Drivers

Base62

  • Drivers: base62 , base62_integer
  • Configuration:
    • characters : 62 unique characters
  • Backend: tuupola/base62
  • Notes:
    • You may use the hashid:alphabet command to generate random characters.
    • GMP is strongly recommended as it is much faster than pure PHP.

Base64

Hashids

  • Drivers: hashids , hashids_hex , hashids_integer , hashids_string
  • Configuration:
    • salt
    • min_length
    • alphabet : At least 16 unique characters
  • Backend: hashids/hashids
  • Notes:
    • You may use the hashid:alphabet command to generate a random alphabet.
    • GMP is strongly recommended.

Hex

  • Drivers: hex , hex_integer

Optimus

  • Drivers: optimus
  • Configuration:
    • prime : Large prime number lower than 2147483647
    • inverse : The inverse prime so that (PRIME * INVERSE) & MAXID == 1
    • random : A large random integer lower than 2147483647
  • Backend: jenssegers/optimus
  • Notes:
    • You may use the hashid:optimus command to generate needed numbers.
    • Only for integer numbers.
    • The max number can be handled correctly is 2147483647.

Custom Drivers

To create a custom Hashid driver, you only need to implement the ElfSundae\Laravel\Hashid\DriverInterface interface that contains two methods: encode and decode. The constructor can optionally receive the driver configuration from a $config argument, and type-hinted dependencies injection is supported as well:

<?php

namespace App\Hashid;

use ElfSundae\Laravel\Hashid\DriverInterface;
use Illuminate\Contracts\Encryption\Encrypter;

class CustomDriver implements DriverInterface
{
    protected $encrypter;

    protected $serialize;

    public function __construct(Encrypter $encrypter, array $config = [])
    {
        $this->encrypter = $encrypter;

        $this->serialize = $config['serialize'] ?? false;
    }

    public function encode($data)
    {
        return $this->encrypter->encrypt($data, $this->serialize);
    }

    public function decode($data)
    {
        return $this->encrypter->decrypt($data, $this->serialize);
    }
}

Now you can configure the connection with this driver:

'connections' => [

    'custom' => [
        'driver' => App\Hashid\CustomDriver::class,
        'serialize' => false,
    ],

    // ...
]

If you prefer a short name for your driver, just register a container binding with hashid.driver. prefix:

$this->app->bind('hashid.driver.custom', CustomDriver::class);

Testing

$ composer test
