PowerShell 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

#  See Global Unlock Sample for sample code.

#  First generate an RSA private key.

#  Generate a random 2048-bit RSA key.

#  Country Name (2 letter code)

#  Organization Name (eg, company)

#  Organizational Unit Name (eg, secion/division)

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

#  Save the private key and CSR to a files.

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

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