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

Chilkat2 Perl

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

# First generate an RSA private key.
my $rsa = Chilkat2::Rsa->new;

# Generate a random 2048-bit RSA key.
my $privKey = Chilkat2::PrivateKey->new;
my $success = $rsa->GenKey(2048, $privKey);
if (!$success) {
    print $rsa->LastErrorText, "\n";
    exit;
}

# Create the CSR object and set properties.
my $csr = Chilkat2::Csr->new;

$csr->CommonName('Admin forInformation-MainShop');

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

# Organization Name (eg, company)
$csr->Company('9999910000');

# Organizational Unit Name (eg, secion/division)
$csr->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.
my $pemStr = $csr->GenCsrPem($privKey);
if (!$csr->LastMethodSuccess) {
    print $csr->LastErrorText, "\n";
    exit;
}

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

my $fac = Chilkat2::FileAccess->new;
$fac->WriteEntireTextFile('qa_output/csr1.pem', $pemStr, 'utf-8', 0);

# Show the CSR.
print $pemStr, "\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
