Advanced OpenPGP users have come to expect their software to support them.

Earlier this month, we connected a set of physical cards to our continuous integration (CI) machine and configured a job to run a test suite on these cards. This setup ensures that every change to our code is tested on a set of physical OpenPGP cards. The ability to test against multiple cards is essential, as cards implement different versions of the specification, and, on top of that, many have various quirks.
