   your own.
2. Upload the Castopod files with `.env`

## Web Server Requirements

### PHP v7.2 or higher

PHP version 7.2 or higher is required, with the following extensions installed:

- [intl](http://php.net/manual/en/intl.requirements.php)
- [libcurl](http://php.net/manual/en/curl.requirements.php) if you plan to use
  the HTTP\CURLRequest library
- [mbstring](http://php.net/manual/en/mbstring.installation.php)

Additionally, make sure that the following extensions are enabled in your PHP:

- json (enabled by default - don't turn it off)
- xml (enabled by default - don't turn it off)
- [mysqlnd](http://php.net/manual/en/mysqlnd.install.php)

### MySQL compatible database

> We recommend using [MariaDB](https://mariadb.org)

You will need the server hostname, database name, username and password to
complete the installation process. If you do not have these, please contact your
server administrator.

#### Privileges

User must have at least these privileges on the database for Castopod to work:
`ALTER`, `DELETE`, `EXECUTE`, `INDEX`, `INSERT`, `SELECT`, `UPDATE`.

### (Optional) Other recommendations

- Redis for better cache performances.
- CDN for better performances.
- e-mail gateway for lost passwords.

## Security concerns

Castopod is built on top of Codeigniter, a PHP framework that encourages
[good security practices](https://codeigniter.com/user_guide/concepts/security.html).

To maximize your instance safety and prevent any malicious attack, we recommend
you update all your Castopod files permissions:

- `writable/` folder must be **readable** and **writable**.
- `public/media/` folder must be **readable** and **writable**.
- any other file must be set to **readonly**.
