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
