NZCP Rust

An implementation of NZ COVID Pass verification, New Zealand's proof of COVID-19 vaccination solution, written in Rust 🦀

We also have a JavaScript implementation available.

Usage

Usage is very straight forward, simply call verify_pass_uri with the scanned QR Code URI. If the given pass is valid the function will return Ok with the pass details, otherwise it will return Err with details of the verification issue.

Add the dependency to your Cargo.toml:

[dependencies]
nzcp = "1.0.2"

use nzcp::{verify_pass_uri, PublicCovidPass};

let barcode = "NZCP: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";
let pass: PublicCovidPass = verify_pass_uri(barcode).await?;

Pass Types

The library is written in a manner which allows easy addition to the types of passes that can be verified, but to date only the My Vaccine Pass spec has been published.

Pass Name	Struct
My Vaccine Pass	`PublicCovidPass`

Usage Outside of Rust

There are plans to provide cross platform libraries using this implementation for other languages, such as web browser WASM and React Native. If you'd like to create your own please do!

SSI rejects DID context

The context listed in the DID document provided by the MoH uses https://w3.org/ns/did/v1, but SSI only permits https://www.w3.org/ns/did/v1. Either SSI will need to permit that context or MoH will need to change the context. I'm unclear which party is violating the DID spec here.
