//  See Global Unlock Sample for sample code.

//  First generate an RSA private key.

//  Specify the Common Name.  This is the only required property.
//  For SSL/TLS certificates, this would be the domain name. 
//  For email certificates this would be the email address.

$csr->Company = 'Internet Widgits Pty Ltd';

//  Organizational Unit Name (eg, secion/division)
$csr->CompanyDivision = 'IT';

//  Email address
$csr->EmailAddress = 'support@mydomain.com';

//  Create the CSR using the private key.
$pemStr = $csr->genCsrPem($privKey);
if ($csr->LastMethodSuccess != 1) {

}

//  Save the private key and CSR to a files.
$privKey->SavePkcs8EncryptedPemFile('password','qa_output/privKey1.pem');

//  Show the CSR.

//  Sample output:
//  The CSR PEM can be checked here:

//  Copy-and-paste the PEM into the online CSR Decoding / CSR Verification form
