Hard Drive and NIC Serial #/ID

[nealpederson]

How can a LabVIEW program get a hard drive and/or NIC serial number/ID in
Windows?

I'd like to programmatically get this information to provide an "unlock"
code for software that has been paid for.

one thing you can do to get the nic card mac address is to use the system exec.vi and execute ipconfig /all and parse the output to get the mac address

Thanks,

I also found a VI that calls Kernel32.dll to get volume information. See:

Now that I am able to read the hard drive serial number and convert it to a
32 bit integer I was wondering what a good encryption routine would be to
perform on this number to create a passcode. I've come up with various bit
shifting routines that may work OK but I'm sure there are much better
routines out there that would be harder to crack. Can anyone recomend one?

nealpederson, I have short question.

Did you get Volume Serial Number or Hard Drive Serial Number? There are two different things. Volume Serial Number can be easy obtained and changed (and as far as I know it changed with every format). But obtaining physical Hard Drive serial number not so easy...

It is the volume serial number. Is this something that can be changed in
the registry?

Yes, Volume Serial Number can be changed.
Not in Registry, but

Changing volume's serial number

Google: how to change volume serial number volume's serial number

and so on...
