Exactly. Before anyone can claim that a digital signature is mine, they need to refute my potential claim that someone else had access to it. If they have forced me to register my private key in a registry someplace where some criminal might have broken in and stolen it, then they can not prove my authorship beyond a reasonable doubt. -- -- <<Disclaimer: All opinions expressed are my own, of course.>> -- Carl Ellison cme@sw.stratus.com -- Stratus Computer Inc.
