As I was saying last year, they are making blockchain-based immunity passports (using DIDs).

The values were changed to a fake person (Taylor Swift) but you can see how it looks. It uses ECDSA for instance.

One interesting thing about those vaccination passports is that they don't provide a public key to verify the signature. That means they rely on a centralized "authority".

@vbhide @verretor The screenshot has been modified so the values are fake but we can more or less guess what is going on.

@vbhide @verretor I'm also unable to read it. Possibly some encoding that we don't know of.

@verretor @verretor if its just an encoding issue we should be able to crack it

@vbhide @verretor There's a bit of plain text like "QR-CODE:PK" and "certificate.json" (twice).

The rest is gibberish but could just be some weird encoding.

@vbhide @verretor I'm probably a moron:

$ file -i decoded
decoded: application/octet-stream; charset=binary

Maybe it's JSON-LD.
