GnuPG will print a warning noting that they key is expired, but beyond that, you seem to have missed the part where I noted that the later keytypes actually allow you to CHANGE THE EXPIRE DATE, making it completely meaningless as a security tool for anything except v3 RSA keys anyway. Furthermore, just because a key has gone beyond the expiration date doesn't mean it's not good to know whether an older message has been tampered with or not -- i.e. there must be a difference between a good-but-expired signature and a bad-but-expired signature -- and therefore an option must be present in any case to tell it to behave exactly the way it does, which is to verify with a warning. The only issue seems to be that the worthlessness of key expiration doesn't seem to be well documented, and that I don't think there's an option to force GPG to fail on expired sigs if you want it to. -- Zed Pobre <email@example.com> a.k.a.
