(PHP ActiveX) SSL Client Certificate

Demonstrates how to connect to an SSL server using a client-side certificate, send a simple message, receive a simple response, and disconnect.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Socket')
$socket = new COM("Chilkat.Socket");

// Create an instance of a certificate store object, load a PFX file,
// locate the certificate we need, and use it for signing.
// (a PFX file may contain more than one certificate.)
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.CertStore')
$certStore = new COM("Chilkat.CertStore");
// The 1st argument is the filename, the 2nd arg is the 
// PFX file's password:
$success = $certStore->LoadPfxFile('chilkat_secret.pfx','secret');
if ($success != 1) {
    print $certStore->LastErrorText . "\n";
    exit;
}

// cert is a Chilkat.Cert
$cert = $certStore->FindCertBySubjectCN('Chilkat Software, Inc.');
if ($certStore->LastMethodSuccess == 0) {
    print $certStore->LastErrorText . "\n";
    exit;
}

$success = $socket->SetSslClientCert($cert);

$ssl = 1;
$maxWaitMillisec = 20000;

// The SSL server hostname may be an IP address, a domain name,
// or "localhost".  You'll need to change this:

$sslServerHost = '123.123.88.88';
$sslServerPort = 8123;

// Connect to the SSL server:
$success = $socket->Connect($sslServerHost,$sslServerPort,$ssl,$maxWaitMillisec);
if ($success != 1) {
    print $socket->LastErrorText . "\n";
    exit;
}

// Set maximum timeouts for reading an writing (in millisec)
$socket->MaxReadIdleMs = 20000;
$socket->MaxSendIdleMs = 20000;

// Send a "Hello Server! -EOM-" message:
$success = $socket->SendString('Hello Server! -EOM-');
if ($success != 1) {
    print $socket->LastErrorText . "\n";
    exit;
}

// The server (in this example) is going to send a "Hello Client! -EOM-" 
// message.  Read it:
$receivedMsg = $socket->receiveUntilMatch('-EOM-');
if ($socket->LastMethodSuccess != 1) {
    print $socket->LastErrorText . "\n";
    exit;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
$success = $socket->Close(20000);

print $receivedMsg . "\n";
