Usage

For load the SSL Certificate ICPBrasil:

use Gaesi\Cert\IcpBrasil\IcpBrasilCertificate;

$icp = new IcpBrasilCertificate();
$icp->parseSSL();

echo $icp->cnpj;   // print the cnpj
echo $icp->name;   // print the name of the CommonName
echo $icp->oidExists('2.16.76.1.3.3'); // true

For load the Certificate ICPBrasil from the text or file:

use Gaesi\Cert\IcpBrasil\IcpBrasilCertificate;

string $cert = "-----BEGIN CERTIFICATE-----MIIG4...XLFw==-----END CERTIFICATE-----";
$icp = new IcpBrasilCertificate();
$icp->parseX509($cert);
echo $icp->cnpj;   // print the cnpj

Verify CertChain

For load and verify the Chain of Certificate :

use Gaesi\Cert\IcpBrasil\IcpBrasilCertificate;

$ca = new CALoader();
$ca->addRepositoryPath('path/to/CAs/repository');

$icp = new IcpBrasilCertificate();
$icp->parseSSL();
$icp->setChain($ca->getCAs());
echo 'Valid? :'. ($icp->validateChain())? 'true' : 'false';

For verify if the Chain of Certificate is a ICP-Basil Chain :

use Gaesi\Cert\IcpBrasil\IcpBrasilCertificate;


$icp = new IcpBrasilCertificate();
$icp->parseSSL();

// Include the Intermediates Certs to the Chain
$ca = new CALoader();
$ca->addCerts( $intermediatesCert ); 

$icp->setChain($ca->getCAs());
echo 'Is IcpBrasil? :'. ($icp->validateICPBrasilChain())? 'true' : 'false';

ICP-Brasil CAs Root

The library store only the default ICP-Brasil CA Root on the directory src/Resources/icpBrasil/Roots, for verify the Chain is necessary load all the Chain of Certificate.
