I'm well aware of issues with the listed hardware devices, and there are
countless others which can be used (hard drive serial number just came to
mind, possibly other such devices). Thank you for addressing it in this
forum, however. In regards to CPU serial numbers, that was another
example.

I'm looking more for comment on algorithm selection and data size. But
thank you for taking the time to respond.
