Please tell me/show me/give examples for how to create this License Generator, and Validator. I can do it in my way, but don't like to mess with this security issue, so decided to take your expertise help.

Anyway, I am in a confuse of how to generate the license(the license algorithm) and how to validate it (according to license algorithm). So, I decided to use client side validation. I am going to use one of paid online 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 ). I don't have any servers, so unable to connect to them. 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.
