There is a tool called caff, which is the de-facto standard when dealing with keysigning (on a large scale, e.g. after a key signing party). This tool hasn't been touch in years, is written and configured in Perl (hence cannot be read and/or maintained :smile:) and is not easy to package, because of a lot of dependencies, etc. It is not even available in our default repositories (at least for Tumbleweed). In general there seems to be a certain kind of frustration with this software, but there is no real alternative available yet.
