use chilkat();

$success = 0;

$certStore = chilkat::CkCertStore->new();

# This opens the Current User certificate store on Windows,
# On MacOS and iOS it opens the default Keychain.
$readOnly = 1;
$success = $certStore->OpenCurrentUserStore($readOnly);
if ($success == 0) {
    print $certStore->lastErrorText() . "\r\n";
    exit;
}

# Locate the certificate containing the specified email address in either the RFC822 Name or the Subject.
$json = chilkat::CkJsonObject->new();
$email_address = 'harold@example.com';
$json->UpdateString("email",$email_address);

$cert = chilkat::CkCert->new();
$success = $certStore->FindCert($json,$cert);
if ($success == 1) {
    # Show the full distinguished name of the certificate.
    print "Found: " . $cert->subjectDN() . "\r\n";
}
else {
    print "Not found." . "\r\n";
