I'm using gnupg to check signatures in a (cron) script, and I'd like gnupg to
exit with an error when --verify displays warnings like :

• Note: This key has expired!
• WARNING: This key is not certified with a trusted signature! There is no

indication that the signature belongs to the owner.

Could it be possible to add to GnuPG an option such as --verify-strict, that
would exit with a non-null return code if the signature is correct but from an
invalid key, expired key, or whatever trust issues GnuPG could lift ?

Keep up the good work !

Best regards
