Hi masters,
I have a software which gives you couple of codes after installation and then i have to call the owner and tell him the code which I'm give by the computer then he gives the password to me to enter the software! Codes are different in different PCs. I wanted to know that anyone knows how can i know the algo of this in order to make a password generator for it? or can i change the software's codes in a way that it could run everywhere using the code i have? any idea? please Help!

Thanks in advance,
