CGI Based Encrypting

I"m looking for help in coding where a username and password is entered and encrypted. Based on the username and password, they are directed to a specific page. The page will be used to give existing customers a login account and take them to specific details (.pdf, .html, .doc, and other files) of thier product. Each product is custom and unique. We do not wish to disclose these details to other, potentially competative, customers. Security is not critical but java script may be too "lax" . TIA

If you are using PHP it supports a good deal about encryption. You can refer PHP manual for more details.

You haven't mentioned your scripting language for the server-side without that i think it would be difficult to comment

Plz provide more details about your requirement
