This project implements an MD5-based encryption scheme on both client and server machines to allow encrypted password protection for web-based Perl/CGI applications. Although there are many free Perl/CGI application for password protection, only a few use MD5 on the server-side, but the password still travels over the internet as plain text. All server-side only schemes (like .htaccess password protection) are completely open to packet-sniffing. With this scheme, the browser JavaScript encrypts the password on the client's machine, and session tracking allows only one response per session ID, making simple packet-sniffing and session replaying much more difficult.
