New blog article: "Using a second #OpenPGP card for my primary key"
https://openpgp.foo/posts/2025-07-a-second-card/
This is a rather niche article, but I hope it will still contain some bits of interest, for at least some readers 馃.
In it, I import my primary OpenPGP key onto a second OpenPGP card hardware device, and use the device to issue a third-party certification with rsop-oct.
I also outline some background and tradeoffs around different OpenPGP card setup.
