Perl Requires Chilkat v11.0.0+

Generate CSR with Uncommon Fields

See more CSR Examples

Demonstrates how to generate a new RSA key and a Certificate Signing Request (CSR) for this:

csr.common.name=Admin forInformation-MainShop
csr.serial.number=1-XYZ|2-2.0|3-999695
csr.organization.identifier=990099994100099
csr.organization.unit.name=9999910000
csr.organization.name=9999910000
csr.country.name=SA
csr.invoice.type=1100
csr.location.address=King Fahed Road
csr.industry.business.category=MainOffice

Perl

use chilkat();

$success = 0;

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

#  First generate an RSA private key.
$rsa = chilkat::CkRsa->new();

#  Generate a random 2048-bit RSA key.
$privKey = chilkat::CkPrivateKey->new();
$success = $rsa->GenKey(2048,$privKey);
if ($success == 0) {
    print $rsa->lastErrorText() . "\r\n";
    exit;
}

#  Create the CSR object and set properties.
$csr = chilkat::CkCsr->new();

$csr->put_CommonName("Admin forInformation-MainShop");

#  Country Name (2 letter code)
$csr->put_Country("SA");

#  Organization Name (eg, company)
$csr->put_Company("9999910000");

#  Organizational Unit Name (eg, secion/division)
$csr->put_CompanyDivision("9999910000");

#  See https://www.alvestrand.no/objectid/2.5.4.html for OIDs for the following fields:

#  csr.serial.number=1-XYZ|2-2.0|3-999695
#  2.5.4.5 - id-at-serialNumber 
$csr->SetSubjectField("2.5.4.5","1-XYZ|2-2.0|3-999695","UTF8String");

#  csr.organization.identifier=990099994100099
#  2.5.4.45 - id-at-uniqueIdentifier   Don't know if this is correct.
$csr->SetSubjectField("2.5.4.45","1100","UTF8String");

#  csr.invoice.type=1100
#  Don't know what this OID would be...
$csr->SetSubjectField("2.5.4.99","1100","UTF8String");

#  csr.location.address=King Fahed Road
#  2.5.4.9 - id-at-streetAddress 
$csr->SetSubjectField("2.5.4.9","King Fahed Road","UTF8String");

#  csr.industry.business.category=MainOffice
#  2.5.4.15 - id-at-businessCategory 
$csr->SetSubjectField("2.5.4.15","MainOffice","UTF8String");

#  Create the CSR using the private key.
$pemStr = $csr->genCsrPem($privKey);
if ($csr->get_LastMethodSuccess() != 1) {
    print $csr->lastErrorText() . "\r\n";
    exit;
}

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

$fac = chilkat::CkFileAccess->new();
$fac->WriteEntireTextFile("qa_output/csr1.pem",$pemStr,"utf-8",0);

#  Show the CSR.
print $pemStr . "\r\n";

#  Sample output:
#  The CSR PEM can be checked here:
#  https://www.networking4all.com/en/support/tools/csr+check/
#  Copy-and-paste the PEM into the online CSR Decoding / CSR Verification form
