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.

//  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.

//  Create the CSR object and set properties.
csr := CkCsr_Create();

//  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.

//  Country Name (2 letter code)

//  State or Province Name (full name)

//  Locality Name (eg, city)
CkCsr_putLocality(csr,'York');

//  Organization Name (eg, company)
CkCsr_putCompany(csr,'Internet Widgits Pty Ltd');

//  Organizational Unit Name (eg, secion/division)
CkCsr_putCompanyDivision(csr,'IT');

//  Email address
CkCsr_putEmailAddress(csr,'support@mydomain.com');

//  Create the CSR using the private key.

if (CkCsr_getLastMethodSuccess(csr) <> True) then
  begin
    Memo1.Lines.Add(CkCsr__lastErrorText(csr));
    Exit;

//  Show the CSR.

//  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
