(JavaScript) Generate Key and Certificate Signing Request (CSR)

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: This example requires Chilkat v11.0.0 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = 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.
var rsa = new CkRsa();

// Generate a random 2048-bit RSA key.
var privKey = new CkPrivateKey();
success = rsa.GenKey(2048,privKey);
if (success == false) {
    console.log(rsa.LastErrorText);
    return;
}

// Create the CSR object and set properties.
var csr = new CkCsr();

// 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. 
csr.CommonName = "mysubdomain.mydomain.com";

// Country Name (2 letter code)
csr.Country = "GB";

// State or Province Name (full name)
csr.State = "Yorks";

// Locality Name (eg, city)
csr.Locality = "York";

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

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

// Email address
csr.EmailAddress = "support@mydomain.com";

// Create the CSR using the private key.
var pemStr = csr.GenCsrPem(privKey);
if (csr.LastMethodSuccess !== true) {
    console.log(csr.LastErrorText);
    return;
}

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

var fac = new CkFileAccess();
fac.WriteEntireTextFile("qa_output/csr1.pem",pemStr,"utf-8",false);

// Show the CSR.
console.log(pemStr);

// 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
