For a program that will be licensed to individual users, I seek a quick solution to read some “personal” data from a user’s computer, such as MAC address, user name, company name etc.
I do not need legal advice and discussion of privacy implications here - I already know enough about that. - This is needed to generate a personal license key for testers who agreed to let me access such info (for purchases, I could simply use their purchase data, but for beta testing this isn’t available).
So, the question is: Which information can I easily read, and how?
