Using SSH on 4.1

[cooldude832]

I've never used ssh before because I have never seen a need for it with the data I have had, but a recent project is requiring the use of it on a server that has 4.1.  I've heard rumors that 4.3 or better is what is needed for SSH, but does any one have a crash course on doing this

<form method="post" action="self">
<input type="text" name="input1" />
<input type="submit" />

Just to do this

<?php
$var = $_POST['input1'];
//store $var in mysql or some other type or storage.

 

As I have said i know nothing about ssh, and I just wondering if I need to add something to the form/add something to the processing part such as a hash to decrypt it.
