Identifying and editing a variable in memory 4458

Disclaimer: I have not performed any changes and before I clarify the legalities, this is of academic interest only.

Basically I've been buttigned a licence key for my fastest home PC as well as my work PC. As I have another slower home PC which I thought I could use to number crunch, I am tempted to use it as it is sitting there doing nothing.

After all (someone correct me if I'm wrong), AFAIK the licence applies on a per-user rather than per-computer basis. Even if it is on a per computer basis then as I've been buttigned 2 licences, as long as I have a max of 2 computers working on my problems, I am OK.

The details of how it works: 1) You run the binary in licence mode; 2) It generates a hardware hash; 3) This hardware hash is encrypted by an unknown function to form the licence key, which is emailed to you and stored on your PC; 4) This licence key is compared with the hardware hash always generated by the program when it runs to see if the hardware "pbuttes".

I'm a "crash & burn" programmer, when something goes wrong I locate the error using Print statements :o

Do you know where I can read up more about this process?

Thanks.
