Generate RSA Key and return Base64 PKCS8 Private Key

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key.

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.

JavaScript

var success = false;

var rsa = new CkRsa();

// Generate a 2048-bit key.  Chilkat RSA supports
// key sizes ranging from 512 bits to 8192 bits.
var privKey = new CkPrivateKey();
success = rsa.GenKey(2048,privKey);
if (success == false) {
    console.log(rsa.LastErrorText);
    return;
}

// Get the private key in PKCS8 Base64 format
var privKeyPkcs8Base64 = privKey.GetPkcs8ENC("base64");

// The key in base64 format will start similar to this:
// MIIEvAIBADANBgkqhkiG9w0BA...
console.log(privKeyPkcs8Base64);
