Overview

Verifies a gem signed by the ‘sign’ command. Iterates through the gem contents and verifies all embedded files, if possible. Errors out if the signature is bad or the key is unknown.

Optionally takes “–get-key” which automatically retreives the key from keyservers to make things easier for people unfamiliar with gpg.
