I am trying to add software licensing to my software, which I am planning to sell (which means if the license if correct, give access to the software. Else, break the access). I don't have any servers, so unable to connect to them. I am going to use "Kagi" service to sell my software ( I don't like to use their server support for licensing too, because it is time for me to get some break ). So, I decided to use client side validation. Anyway, I am in a confuse of how to generate the license(the license algorithm) and how to validate it (according to license algorithm). I can do it in my way, but don't like to mess with this security issue, so decided to take your expertise help. Please tell me/show me/give examples for how to create this License Generator, and Validator. And, if you are posting an example with an algorithm, please be kind enough to explain it if you think it is complex. Because then only I can create one of my own
Are you better than me? Then please show me my mistakes..
