(I do not disagree with Kevin: this is an emphatic agreement.) There is a minimum energy associated with flipping a bit -- something so small that a single proton has the energy to flip about a trillion bits. Let's say you have a remarkably efficient OS that can test a given key while only flipping 10,000 bits. Multiply that times the number of attempts you'd have to make to brute-force a 128-bit key and you get a really big number, so big that it no longer makes sense to describe it in terms of nuclear warheads. The best, most visceral way of saying it is, "You must have 340 kilos of antimatter to run your computer." If you happen to have 340 kilos of antimatter lying around, then yes, brute-forcing is certainly possible. I deeply hope you don't. I like Earth: all my stuff is here. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
