Help with the signed header #12

Open ZuzzuWasTaken opened 2 years ago

ZuzzuWasTaken commented 2 years ago

I’d love for someone to tell me where to find this fucking "signed header". I actually have a working green pass but the script entered in #1 doesn’t generate anything. I ask you to please help me. Thank you

As you may know the QR is kind of a Matryoshka doll with layers of encoding, .e.g.: QR Text data → Base45 → Zlib → CBOR. That CBOR has 4 fields: [header1, header2, payload, signature]. I'm no expert on CBOR, you'd have to do some Googling around, but it looks like the signature is an integral part of CBOR.

Nice start but doesn't work. No Zlib

I'm sorry, but it does use Zlib compression.
