Software Activation using the Internet

Have you ever wanted an easy-to-use method of product activation over the Internet? Well, here is one. A serial number generator is included. You only need to upload one file onto your webserver called writeFile.php You only need PHP. MYSQL is not required. I have downloaded some code from others and included it here but I cannot remember who the authors are...sorry. I have used this method (but with a different mathematical algorithm) on my new program which I am hopefully going to sell. I will post snippets of my new program (KTK File Explorer) in the future.
