If by "too liberal" you mean "it's possible to do it," then I don't see how to avoid it. You'd need a trusted timestamp on the certificate and a trusted timestamp on the machine using the certificates, and trusted timestamps are a hard, *hard* problem. Yes, OpenPGP is quite permissive about letting people encrypt to expired certificates, but I think that's more a factor of it being incredibly hard to prevent it than it is any neglect on the part of the OpenPGP authors. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
