Hardware keys

Rune Allnor

Hi all.

I consider to let a client have a test version of some of
my software. If the software turns out to do what it is
supposed to do, I would like to protect it from being
distributed, e.g. by using hardware keys. The software
in question is written in C++.

1) How does one use hardware keys to protect programs?
That is, what voodoo is involved from the programming POV.
2) Where can I find vendors of hardware keys?

Thanks in advance,

Rune

A hardware key and a dev kit to exploit it.

Google it. I think Microcosm has also Internet key solutions.
This question is best suited for a professional network (LinkedIn ?)

This may be an obsolete business model to sell secret bits. Once your
bits are reverse engineered you are in trouble.
