Today an email reached us, asking for a digital rights management procedure, binding the user identification to the purchased file. Well, this is indeed possible, but we have to manually configure for you.
The process includes that your signing application, means the logic of the "DRM" fingerprint system is available on either Linux, or that you provide us with an URL, where we might generate the fingerprint from OUR IP number and get the encrypted data back via HTTPS.
We prefer the first solution! Just ask me or my colleagues, what you are aiming for and what you need to protect.
Cheers,
Puzzler
