        // generates a unique prefix for the current instance. this is only to prevent collisions when running multiple
        // ILIAS Instances on the same server. It uses the md5 hash of the current working directory and takes the first
        // 6 characters. This is not a secure way to generate a prefix, but it is sufficient for this purpose.
        // It's highly unlikely that two paths will result in the same prefix.
