Get the Certificate with Private Key from a Java KeyStore

Load a Chilkat certificate object from a Java KeyStore. PHP Extension

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

// Most of the time a .jks contains one certificate with it's associated private key.
// (Similar to how a .pfx/.p12 usually contains a particular certificate with private key.)
// This example demonstrates how to get the certificate with private key such that it can be used
// by other Chilkat classes wherever a cert w/ private key is needed.
$jks = new CkJavaKeyStore();
$password = 'secret';
$success = $jks->LoadFile($password,'qa_data/jks/test_secret.jks');

    print $jks->lastErrorText() . "\n";
    exit;
}

// Make sure we have a private key.
if ($jks->get_NumPrivateKeys() < 1) {
    print 'No private key available.' . "\n";

// Get the certificate chain associated with the 1st (and probably only) private key in the JKS.

// Verify again that this cert has a private key.

// We now have the cert object with it's associated private key, and it can be used in other Chilkat classes where needed.
// For example..
