Say I have a CGI script that updates html files on my website. Every so often, a user comes along to modify those files through the CGI script. The easiest method to keep potential hackers out is to use basic authentication. Unfortunately, this form of encryption is easily cracked by a determined hacker. SSL is not an option in this environment. What are some other options to keep unauthorized people from using this script? Hopefully this will generate some discussion regarding various methods of web security...
