How to add unlock functionality to a program
« on: September 12, 2018, 05:33:29 am »
Hi
Does anyone have experience with adding unlock functionality to a program, so that it can be unlocked (after payment) via a serial key?
If so can you give any advice/tips or provide any useful links?
Ok thanks

Worked out I can use MD5 quite good. If 4 licenses are allowable per user (email address) the person has a 1 in 75 trillion chance of picking a working combo.... but, one person could buy one license and then just send that to everyone

KRISSSSSSSSSSSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Gonna have to put a notifier in.
