Encryption

Introduction

Laravel provides facilities for strong AES encryption via the Mcrypt PHP extension.

Basic Usage

Encrypting A Value

$encrypted = Crypt::encrypt('secret');

Be sure to set a 16, 24, or 32 character random string in the key option of the config/app.php file. Otherwise, encrypted values will not be secure.

Decrypting A Value

$decrypted = Crypt::decrypt($encryptedValue);

Setting The Cipher & Mode

You may also set the cipher and mode used by the encrypter:

Crypt::setMode('ctr');
 
Crypt::setCipher($cipher);
