While you're in this area, you could clarify that the keys in key1 and key2 are public keys. For example:
- the second key, as 32 bytes. The key to use depends on the mode field
- if
0x00, then what the device thinks the other user's master cross-signing public key is- if
0x01, then what the device thinks the other device's Ed25519 signing public key is- if
0x02, then what the device thinks the user's master cross-signing public key is

[sadly yes, the spec for QR codes is copyrighted; this seems to be the best we can do.]

Pull Request Checklist
Currently the spec is specific about the contents of the binary data to be present within a QR, but it does not specify how that data should be encoded within a QR.
I've checked the original MSC1544 but don't see any obvious discussion around this. Also, no discussion in the spec PR.
As such, I assume this is an oversight.
I do have a hesitation about linking out to the ISO spec as it is not "open".
