I wish we could encode PGP public keys with them, but it's still too much data.

That would be a neat way of exchanging a key.

You can definitely encode ed25519 keys to a QR code.

How big is your pgp public key? Mine is under 4K in ascii and can definitely fit in a QR code.

If you use a crypto atm it will print out your wallet’s private and sometimes public keys as QR codes.

4K is around the point where some devices will start to have issues scanning. Also, crypto wallets won’t usually give you the private key, instead they’ll give you the 12 word BIP39 seed phrase which will be around 70-80 bytes.

Gpg key fingerprints are very small though and can be used for that.
