GPG key support?

Would be great if this tool could generate ed25519 keys with vanity pubkey fingerprint for use in gpg.

PGP fingerprints probably work quite differently.
Would need to investigate.
Not sure if it's worth my time.
Quite a lot of things could benefit from fast ed25519 keygen but someone has to make it work.
PRs and implementation related questions are probably kinda welcome if anyone wants to try.

oh also someone mentioned that PGP fingerprint might have some more fields included, some of them freely modifiable which would be a whole lot faster than whatever ed25519 math my tool does.

Thanks. Unfortunately they don't have Curve25519 support, but I'll keep looking.

ah, rip, but it shouldn't be hard to fix that, their method don't really rely on certificate type, but I guess it's coded in not-so-flexible way.
