Did you know SSH can sign files?
And you can look up public keys on GitHub?
This post explains a simple PKI already on most computers, that already has public keys for most people on GitHub:

Thanks to for implementing this!

I'd guess that at least one order of magnitude more people have SSH keys configured and stored on GitHub than have gpg keys published in a key server. Maybe two orders of magnitude.

Right, and the latter are what GPG gets horribly wrong (in the ux department at least).

PGP has serious flaws such as inherently depending on SHA-1 and having a ridiculous amount of legacy cruft and bloat. The whole web of trust thing is pretty much harmful nonsense, at least as designed. GPG has serious implementation issues beyond all that. I've migrated away.

What are your thoughts on github.com/FiloSottile/age? I've been thinking the same thing, and what I really require is whatever _____ I use must live on my hardware Yubikey.

Just going to set up my email server to automatically reject PGP encrypted emails and send a response telling people to contact me on Matrix. Matrix and signify cover nearly all my use cases for it. If I ever actually want to encrypt a file anonymously, I'll use age for that.
Don't try to use signify + age for secure messaging instead of a proper secure messaging app with forward secrecy, a good verification system, etc.

Also see twitter.com/DanielMicay/st. An HSM no secure input, no secure display and the lack of a secure backup system is quite flawed. Needing to generate a key on a general purpose computer to back it up and import it into the HSM is a bad design. Can do a lot better than that.

In general, I don't think an HSM without secure input and output can actually provide as much as people expect from them.
For example, a hardware wallet for Bitcoin with no display lets an attacker send a million dollars to themselves when you confirm buying a pizza with it.
