How long a today 'secure' key will remain secure? When will quantum computers be widely available? The only "guaranteed" crypto is information-theoretic one (neural networks mutual learning, distant noisy sources, etc), where adversary's probability of success is a function of the system parameters. But it's quite impractical and AFAIK covers only interactive key agreement.
PS: in 100 years surely I won't (be here to) care if someone will be able to read my mails or not :) BYtE, Diego _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
