AutoIt Requires Chilkat v11.0.0+

Generate Key and Certificate Signing Request (CSR)

See more CSR Examples

Demonstrates how to generate a new RSA key and a Certificate Signing Request (CSR).

Note: This example requires Chilkat v9.5.0.65 or greater.

AutoIt

Local $bSuccess = False

;  Note: Requires Chilkat v9.5.0.65 or greater.

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

;  First generate an RSA private key.
$oRsa = ObjCreate("Chilkat.Rsa")

;  Generate a random 2048-bit RSA key.
$oPrivKey = ObjCreate("Chilkat.PrivateKey")
$bSuccess = $oRsa.GenKey(2048,$oPrivKey)
If ($bSuccess = False) Then
    ConsoleWrite($oRsa.LastErrorText & @CRLF)
    Exit
EndIf

;  Create the CSR object and set properties.
$oCsr = ObjCreate("Chilkat.Csr")

;  Specify the Common Name.  This is the only required property.
;  For SSL/TLS certificates, this would be the domain name. 
;  For email certificates this would be the email address. 
$oCsr.CommonName = "mysubdomain.mydomain.com"

;  Country Name (2 letter code)
$oCsr.Country = "GB"

;  State or Province Name (full name)
$oCsr.State = "Yorks"

;  Locality Name (eg, city)
$oCsr.Locality = "York"

;  Organization Name (eg, company)
$oCsr.Company = "Internet Widgits Pty Ltd"

;  Organizational Unit Name (eg, secion/division)
$oCsr.CompanyDivision = "IT"

;  Email address
$oCsr.EmailAddress = "support@mydomain.com"

;  Create the CSR using the private key.
Local $sPemStr = $oCsr.GenCsrPem($oPrivKey)
If ($oCsr.LastMethodSuccess <> True) Then
    ConsoleWrite($oCsr.LastErrorText & @CRLF)
    Exit
EndIf

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

$oFac = ObjCreate("Chilkat.FileAccess")
$oFac.WriteEntireTextFile("qa_output/csr1.pem",$sPemStr,"utf-8",False)

;  Show the CSR.
ConsoleWrite($sPemStr & @CRLF)

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

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