(Visual FoxPro) 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 loRsa
LOCAL lnSuccess
LOCAL loPrivKey
LOCAL loCsr
LOCAL lcPemStr
LOCAL loFac

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

* First generate an RSA private key.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rsa')
loRsa = CreateObject('Chilkat.Rsa')

* Generate a random 2048-bit RSA key.
lnSuccess = loRsa.GenerateKey(2048)
IF (lnSuccess <> 1) THEN
    ? loRsa.LastErrorText
    RELEASE loRsa
    CANCEL
ENDIF

* Get the private key
loPrivKey = loRsa.ExportPrivateKeyObj()

* Create the CSR object and set properties.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Csr')
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 loPrivKey
    RELEASE loRsa
    RELEASE loCsr
    CANCEL
ENDIF

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.FileAccess')
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
