PHP Encrypter
=============

[](#php-encrypter)

This project encrypts and decrypts the given value. It uses OpenSSL extension with AES-256 cipher for encryption and HMAC-SHA-256 for hash. The encryption and hash can use different keys.

PHP Encrypter requires PHP 5.3 or higher, OpenSSL and Multibyte String extensions.

### Security Notice

[](#security-notice)

As a reversible operation, encryption is not a secure solution for storing passwords. Always use hashing with salt per user for passwords.

Installation
------------

[](#installation)

#### With [Composer](https://getcomposer.org/):

[](#with-composer)

```
composer require adbario/php-encrypter

```

#### Manual installation:

[](#manual-installation)

1. Download the latest release
2. Extract the files into your project
3. require\_once '/path/to/php-encrypter/src/Encrypter.php';
4. If your PHP version is lower than 7, also [polyfill for random\_bytes()](https://github.com/paragonie/random_compat) is required

Usage
-----

[](#usage)

Setup the encryption key:

```
$key = '+NeXrQhAEhW}g8gf^y)Up8hAUKpue7wb';
```

**Change the key to your own custom random 32 character string.**

Create a new encrypter instance:

```
$encrypter = new \Adbar\Encrypter($key);
```

If you wish to use a different key for hashing, you can pass it to constructor as a second parameter:

```
$encrypter = new \Adbar\Encrypter($key, $authKey);
```

### Encryption

[](#encryption)

Encrypt a string:

```
$string = 'This is my string to encrypt.';
$encrypted = $encrypter->encryptString($string);
```

Encrypt other variable types with serialization:

```
$array = array('key' => 'value');
$encrypted = $encrypter->encrypt($array);
```

### Decryption

[](#decryption)

Decrypt a string:

```
$string = $encrypter->decryptString($encrypted);
```

Decrypt other variable types with serialization:

```
$array = $encrypter->decrypt($encrypted);
```
