Integrate phpseclib into Laravel 5

i am currently migrating my Project from Laravel 4 to Laravel 5, i am still a novice user of Laravel and OOP as well but everything went smoothly so far. However, in my L4 project I use the phpseclib for generating SSH keys which I imported in the following way: MyController.php ``` ... include('../app/libs/phpseclib0.3.10/Crypt/RSA.php'); $rsa = new Crypt_RSA(); ... ``` which does not seems to work anymore: ``` syntax error, unexpected 'if' (T_IF), expecting identifier (T_STRING) ``` .../app/libs/phpseclib0.3.10/Crypt/RSA.php ``` /** * Include Crypt_Random */ // the class_exists() will only be called if the crypt_random_string function hasn't been defined and // will trigger a call to __autoload() if you're wanting to auto-load classes // call function_exists() a second time to stop the include_once from being called outside // of the auto loader if (!function_exists('crypt_random_string')) { include_once 'Random.php'; } ``` I know that there is a phpseclib package: https://packagist.org/packages/phpseclib/phpseclib and I also know how to Install it in my L5 Project. However, I dont know how to use the phpseclib package in my Laravel 5 project after I installed it. So, after I installed the phpseclib package in my L5 Project, how to create my SSH Key similar to this: ``` $rsa = new Crypt_RSA(); ```
