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.

- prepend 7y agoHow 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.

- BiteCode_dev 7y agoGpg key fingerprints are very small though and can be used for that.
