Yeah, go back and read your own posting. Every starport has at least one key, if not dozens, or hundreds, to read all of the transponders of the ships coming into the system. I wasn't talking about YOUR personal key. And if it's YOUR personal key, I don't doubt it's still safe. Do you have anything worth stealing that a hacker would bother to do so?
I said that as a joke. As you know, you can't derive a private key from having a correctly generated Public key. THAT is why my private key is still secure. Not, because how many or, how few copies are out in the wild.
Where did you find that statistic?.
From an internal presentation at DHS by NRO crypto. (The current public/private scheme won't be able to be factored until ~2034 based on current computer speed growth curve. Using A LOT of networked machines that a civvie could likely use, it is in that figure I gave.
p.s. I've worked the IT sec area (retired now) for many years and participated in public (US intel & law) private sector & consulting NATO member internal sec ministries.
