Since "absolute" security is absolutely unattainable aren't we actually obliged to do this (unless we're in it for amusement sake only)? Isn't "good enough" good enough? PGP seems good enough to me, but, then, I've only got small secrets. And a public key posted here is just a supply of envelopes. Richard
