Help with webSite...CGI??

[dwj100uni]

Hi there everyone.

I was wondering if any of you could help me.....

I am creating a small website so that a user can enter some text into a box, and then, using a certain key, the site will encrypt the data and send it back to the user on the next page so they can print it out, etc....

I was just wondering how I can get a program to take the text entered in a text box on a form and convert it (obviously server side) and then send it back to the user on the next page? What do i use? Can i use Java as i know this a bit.

Any help appreciated,

David

Here's a very simple example.
#!/usr/bin/perl -w

use Digest::MD5 qw(md5_hex);

$data = 'A line of unknown text';
$digest = md5_hex($data); # create a hexadecimal digest

print $digest;Outputs:2af1b788073c11b149efda57090906ad

You may want to consider using the JavaScript MD5 module (the first link that I posted). The module's documentation has a good example of its usage.
