C# WPF Software - Needs Licensing/Activation

Hi there, I have a software that is limited in function. It has an implemented activation mechanism. The way it works is 1. Customers sends me his MachineGUID 2. I use a key generator to generate his serial key. 3. I send it back to him 4. He inputs it in the software and the program unlocks. The “serial key” is just the same “MachineGUID” scripted using a secret that the app and the key generator share. ----------------------------------- But what I am looking for is an automated way for them to receive a serial key without me having to do it. For the serial key to be generated automatically or by them. My programmer told me this 1. Get a windows web server 2. Use the .dll I provided ( used to generate codes) 3. Get someone to do the server/client scripting So my question is, do you have the knowledge to implement this on my software? If you are CERTAIN you do. Please bid now. If you THINK you can. Please don't bid. I am looking for someone who is confident they can complete the project. It is coded in C# WPF. --------------------------------------- WARNING! 1. If you do NOT MEET THE REQUIREMENTS please do not bid. - you are wasting your time 2. If hired project must be completed within the deadline you will NOT GET PAID - you are wasting your time 3. Please mention the keyword "blackbird" in your message if you have read this far or your bid will be ignored . This is to exclude those who don't take the time to read the project details.. -----------------------------------------
