1.1. Who should use phpseclib

- Although many of the features this library implements are implemented in PHP via optional extensions, what are - you, as a developer, going to do when a user tries to run your software on a host which, coincidentally, doesn't - happen to have that optional extension installed? You could, flat-out, tell that user to look for another - software package that does work on their server (or to get another host, or whatever), which is liable to leave - a bad impression on the user, or you could use a library like this - a library that uses those optional - extensions if they're available and falls back on an internal PHP implementation if they're not. -

- Another advantage of using this library over optional PHP extensions is that you, as a developer, may find this - libraries API easier to use then extensions API. -

1.2. Using phpseclib

- This library is written using the same conventions that libraries in the PHP Extension and Application Repository (PEAR) - have been written in. In particular, this library expects to be in your include_path: -

<?php
-set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');
-
-include('Net/SSH2.php');
-?>
