ESIA Provider for OAuth 2.0 Client
 
 
 , (*1)
, (*1)
Allows to authenticate in ESIA and get authenticated individual personal information., (*2)
Implemented as adapter to the PHP League's OAuth 2.0 Client., (*3)
Installing
To install, use composer:, (*4)
composer require ekapusta/oauth2-esia
Usage
Usage is the same as the normal client, using Ekapusta\OAuth2Esia\Provider\EsiaProvider as the provider:, (*5)
use Ekapusta\OAuth2Esia\Provider\EsiaProvider;
use Ekapusta\OAuth2Esia\Security\JWTSigner\OpenSslCliJwtSigner;
use Ekapusta\OAuth2Esia\Security\Signer\OpensslPkcs7;
$provider = new EsiaProvider([
    'clientId'      => 'XXXXXX',
    'redirectUri'   => 'https://your-system.domain/auth/finish/',
    'defaultScopes' => ['openid', 'fullname', '...'],
// For work with test portal version
//  'remoteUrl' => 'https://esia-portal1.test.gosuslugi.ru',
//  'remotePublicKey' => EsiaProvider::RESOURCES.'esia.test.public.key',
// For work with GOST3410_2012_256 signatures (instead of default RS256)
//  'remoteCertificatePath' => EsiaProvider::RESOURCES.'esia.gost.prod.public.key',
], [
    'signer' => new OpensslPkcs7('/path/to/public/certificate.cer', '/path/to/private.key'),
// For work with GOST3410_2012_256 signatures (instead of default RS256)
//    'remoteSigner' => new OpenSslCliJwtSigner('/path/to/openssl'),
]);
Which signer to use?
- If you use RSA keys, then OpensslPkcs7is enough.
- If you use GOST keys and compiled PHP with GOST ciphers, then OpensslPkcs7is enough.
- If you use GOST keys and have openssl-compatible tool, then use OpensslCli. It hastoolpathparam.
- If you use GOST keys and you are docker-addict, then you can use 'toolpath' => 'docker run --rm -i -v $(pwd):$(pwd) -w $(pwd) rnix/openssl-gost openssl'.
Which remote signer to use?
- If your system electronic signature algorythm is default RS256, then do nothing.
Under the hood it uses Sha256 remote signer.
- If you use GOST3410_2012_256 signature, then use OpenSslCliJwtSigner, passing to it path toopenssltool. For dockers pass to it something likedocker run --rm -i -v $(pwd):$(pwd) -v /tmp/tmp -w $(pwd) rnix/openssl-gost openssl'./tmpvolume is important there!
Auth flow
Auth flow is standard., (*6)
// https://your-system.domain/auth/start/
$authUrl = $provider->getAuthorizationUrl();
$_SESSION['oauth2.esia.state'] = $provider->getState();
header('Location: '.$authUrl);
exit;
// https://your-system.domain/auth/finish/?state=...&code=...
if ($_SESSION['oauth2.esia.state'] !== $_GET['state']) {
    exit('The guard unravels the crossword.');
}
$accessToken = $provider->getAccessToken('authorization_code', ['code' => $_GET['code']]);
$esiaPersonData = $provider->getResourceOwner($accessToken);
var_export($esiaPersonData->toArray());
Simplified facade
If you don't like classes with about 20 public methods, there is simplified facade-class., (*7)
use Ekapusta\OAuth2Esia\EsiaService;
$service = new EsiaService($provider);
// https://your-system.domain/auth/start/
$_SESSION['oauth2.esia.state'] = $service->generateState();
$authUrl = $service->getAuthorizationUrl($_SESSION['oauth2.esia.state']);
header('Location: '.$authUrl);
exit;
// https://your-system.domain/auth/finish/?state=...&code=...
$esiaPersonData = $service->getResourceOwner($_SESSION['oauth2.esia.state'], $_GET['state'], $_GET['code'])
var_export($esiaPersonData->toArray());

About ESIA
There are three ESIA user identification levels:, (*9)
- simple
- standard
- confrimed
Information system can ask info about user from individuals register., (*10)
ESIA user could be:, (*11)
- individual
- individual entrepreneur (individual + flag "is entrepreneur")
- individual connected to legal entities accounts
- individual connected to public authorities accounts
Users after individual can be only of confirmed identification level., (*12)
User info
After user's permission his/her info can be read through REST., (*13)
Scopes
To get some info about user system should ask it through "scope" param.
Same param entered in paper-written application for connection to ESIA., (*14)
Scope is analog of permissions in mobile apps, but for user's data., (*15)
Here are list of possible scopes: fullname, birthdate, gender, snils, inn, id_doc,
birthplace, medical_doc, military_doc, foreign_passport_doc, drivers_licence_doc,
vehicles, email, mobile, contacts, kid_fullname., (*16)
Security algos
ESIA REST supports both RSA2048+SHA256 and GOST3410-2001+GOST341194 algos., (*17)
Authentication methods
There are two ways to authenticate user: SAML 2.0 and OpenID Connect 1.0 (OAuth 2.0 extension).
SAML 2.0 is only for public authorities., (*18)
For legal entities OpenID Connect is used., (*19)
Terms
ESIA from Russian "ΠΠ‘ΠΠ", which is "ΠΠ΄ΠΈΠ½Π°Ρ ΡΠΈΡΡΠ΅ΠΌΠ° ΠΈΠ΄Π΅Π½ΡΠΈΡΠΈΠΊΠ°ΡΠΈΠΈ ΠΈ Π°ΡΡΠ΅Π½ΡΠΈΡΠΈΠΊΠ°ΡΠΈΠΈ".
Translated as "Unified identification and authentication system"., (*20)
