pUZI php

Proficient UZI pass reader in php.

The UZI card is part of an authentication mechanism for medical staff and doctors working in the Netherlands. The cards are distributed by the CIBG. More information and the relevant client software can be found at www.uziregister.nl (in Dutch).

pUZI is a simple and functional module which allows you to use the UZI cards as authentication mechanism. It consists of:

1. a reader that interprets the PKCS11 data the card middleware provides to the webserver and returns an UziUser object in return (this repository).
2. middleware (currently only for the Laravel framework) that allows authentication and user creation based on UZI cards.

For documentation, software and to apply for an UZI card, please check out www.uziregister.nl.

pUZI is available under the EU PL licence. It was created early 2021 during the COVID19 campaign as part of the vaccination registration project BRBA for the ‘Ministerie van Volksgezondheid, Welzijn & Sport, programma Realisatie Digitale Ondersteuning.’

Installation

Composer

composer require minvws/puzi-php

Manual

Add the following to your composer.json and then run composer install.

{
    "require": {
        "minvws/puzi-php": "^0.2"
    }
}

Usage

// Request from your framework/controller
$uzi = new \MinVWS\PUZI\UziReader();
$user = $uzi->getDataFromRequest($request);
print $user->getUziNumber();

// In case of no request (deprecated):
$uzi = new \MinVWS\PUZI\UziReader();
$user = $uzi->getData();

print $user->getUziNumber();
var_dump($user->toArray());

array(9) {
  'givenName' =>
  string(4) "john"
  'surName' =>
  string(12) "doe-11111111"
  'OidCa' =>
  string(25) "2.16.528.1.1003.1.3.5.5.2"
  'UziVersion' =>
  string(1) "1"
  'UziNumber' =>
  string(8) "11111111"
  'CardType' =>
  string(1) "N"
  'SubscriberNumber' =>
  string(8) "90000111"
  'Role' =>
  string(6) "01.015"
  'AgbCode' =>
  string(8) "00000000"
}

This package also allows validation of the returned user:

$allowedTypes = [
    UziConstants::UZI_TYPE_CARE_PROVIDER,
    UziConstants::UZI_TYPE_NAMED_EMPLOYEE,
];
$allowedRoles = [
    UziConstants::UZI_ROLE_DOCTOR,    
    UziConstants::UZI_ROLE_PHARMACIST,    
];

$validator = new UziValidator(true, $allowedTypes, $allowedRoles);
if ($validator->isValid($user)) {
    print "Validated as doctor or pharmasist";
}

You can use either isValid(), which returns a boolean, or validate() which throws an exception when not correctly validated.
