No. This isn't the sort of question that Moore's Law is useful in addressing. You need to get down into the physical limits of the universe -- particularly things like the Bekenstein and Landauer bounds, the Margolus-Levitin limit, and so on. This has been discussed at length on this list before. A good synopsis can be found at: http://lists.gnupg.org/pipermail/gnupg-users/2010-December/040123.html It's worth noting that these limits are all physical constraints of the universe. As such, if a computer operating at the physical limits of the universe can't brute-force something, it's fair to say that it simply cannot be brute-forced. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
