Yes, no and maybe. Yes: if a 1024-bit master signing key can be compromised, there's nothing to prevent the attacker from revoking your 4k subkeys and adding new 4k subkeys the attacker controls. This is really just the tip of the iceberg, as far as attacks go. No: breaking a 1024-bit master signing key is not trivial. Nobody with two brain cells to rub together will try to break a 1024-bit key so long as any other reasonable option exists. I would be surprised if any 1024-bit key has ever been broken, and only slightly less surprised if one were to be broken in the next, say, five years. Maybe: like Yogi Berra said, "the difference between theory and practice? In theory there is no difference: in practice there is." _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
