We have a security situation with a shrink wrapped VB6 App, that our company made and sells internationally.
There is a function in the App which allows the user to transfer licenses between PC’s, which we now suspect is open to abuse…
As a rethink of our strategy, we considered using GUID’s (and their nature) as a public key, which could at least validate any programmatic actions we request them to take are performed, before we release serial keys.
The key things I would like to know about GUID’s are these:
What is a GUID composed of?
Does it contain a ‘Hexadecimal Date-Time- Stamp’?
If it does could this be extracted and converted to a ‘String Date-Time-Stamp’?
That’s basically it… Just knowing if the above is possible would help!!
If you could provide some VB code which perform this function, that would qualify you for extra Karma.
Good luck…
