(PHP Extension) Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers.

<?php

include("chilkat.php");
// Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0

$cert = new CkCert();

// If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
$cert->put_SmartCardPin('12345678');

// To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
// When testing in this way, it's best to have only a single smartcard or token connected to the system.
$success = $cert->LoadFromSmartcard('');
if ($success == false) {
    print $cert->lastErrorText() . "\n";
    print 'Certificate not loaded.' . "\n";
    exit;
}

// The LastErrorText property on all Chilkat objects will contain 
// information even when the method call is successful.
// You can examine the LastErrorText to see what Chilkat found and
// what decisions were made.
// 
// For example, if a certificate was successfully loaded via LoadFromSmartcard,
// but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
// then we would want to examine the LastErrorText from the call to
// LoadFromSmartcard to get detailed information about the card.
print $cert->lastErrorText() . "\n";

print 'Found: ' . $cert->subjectDN() . ' serial=' . $cert->serialNumber() . "\n";
