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

LOCAL lnSuccess
LOCAL loRsa
LOCAL loPrivKey
LOCAL loCsr
LOCAL lcPemStr
LOCAL loFac

lnSuccess = 0

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

*  First generate an RSA private key.
loRsa = CreateObject('Chilkat.Rsa')

*  Generate a random 2048-bit RSA key.
loPrivKey = CreateObject('Chilkat.PrivateKey')
lnSuccess = loRsa.GenKey(2048,loPrivKey)
IF (lnSuccess = 0) THEN
    ? loRsa.LastErrorText
    RELEASE loRsa
    RELEASE loPrivKey
    CANCEL
ENDIF

*  Create the CSR object and set properties.
loCsr = CreateObject('Chilkat.Csr')

loCsr.CommonName = "Admin forInformation-MainShop"

*  Country Name (2 letter code)
loCsr.Country = "SA"

*  Organization Name (eg, company)
loCsr.Company = "9999910000"

*  Organizational Unit Name (eg, secion/division)
loCsr.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 
loCsr.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.
loCsr.SetSubjectField("2.5.4.45","1100","UTF8String")

*  csr.invoice.type=1100
*  Don't know what this OID would be...
loCsr.SetSubjectField("2.5.4.99","1100","UTF8String")

*  csr.location.address=King Fahed Road
*  2.5.4.9 - id-at-streetAddress 
loCsr.SetSubjectField("2.5.4.9","King Fahed Road","UTF8String")

*  csr.industry.business.category=MainOffice
*  2.5.4.15 - id-at-businessCategory 
loCsr.SetSubjectField("2.5.4.15","MainOffice","UTF8String")

*  Create the CSR using the private key.
lcPemStr = loCsr.GenCsrPem(loPrivKey)
IF (loCsr.LastMethodSuccess <> 1) THEN
    ? loCsr.LastErrorText
    RELEASE loRsa
    RELEASE loPrivKey
    RELEASE loCsr
    CANCEL
ENDIF

*  Save the private key and CSR to a files.
loPrivKey.SavePkcs8EncryptedPemFile("password","qa_output/privKey1.pem")

loFac = CreateObject('Chilkat.FileAccess')
loFac.WriteEntireTextFile("qa_output/csr1.pem",lcPemStr,"utf-8",0)

*  Show the CSR.
? lcPemStr

*  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
