Generate Issuer Keyfile
Do you want to issue QR codes to people who have been vaccinated against Covid-19?
Great! All you need to do is generate an "issuer keyfile" that you will use to issue QR codes.
When you first generate your issuer keyfile,
you'll only be able to use it for internal purposes
(i.e. it won't be trusted anywhere).
To start to be trusted as an issuer by others, ask that your keyfile be included in the official issuers list.
