# Digital Green Certificate (DGC)
*DGC* is a PHP library that decodes Digital Green Certificates. In short, it decodes COVID-19 certificates.
## Install
Install with [composer](https://getcomposer.org/).
```bash
$ composer require causal/dgc
```
## Usage
```php
$decoder = new \Causal\DGC\Decoder();
// The string as embedded in the QR code of the certificate (e.g., you can use https://qrafter.com/)
$input = 'HC1:NCFOXNYTSFDHJI89.O%26V$L.BUTRDUV...';
// Extract issuer, issuing date, expiring date, type of vaccine, manufacturer, etc.
$data = $decoder->decodeFromQR($input);
```
```json
{
1: "DE",
4: 1643356073,
6: 1622316073,

nam: {
fn: "Mustermann",
gn: "Erika",
fnt: "MUSTERMANN",
gnt: "ERIKA"
},
ver: "1.0.0"
}
}
}
```
You may then prettify the data so that they are more human-readable:
```php
// Basically this returns the exact same data you read in the official Swiss app "Covid Cert"
$humanReadableData = $decoder->prettify($data);
```
```json
{
issuer: "DE",
issuingDate: "2021-05-29T21:21:13+02:00",
