(C# UWP/WinRT) 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.

Chilkat.Rsa rsa = new Chilkat.Rsa();

bool success;

// Generate a 2048-bit key.  Chilkat RSA supports
// key sizes ranging from 512 bits to 8192 bits.
success = rsa.GenerateKey(2048);
if (success != true) {
    Debug.WriteLine(rsa.LastErrorText);
    return;

Chilkat.PrivateKey privKey = rsa.ExportPrivateKeyObj();

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

// The key in base64 format will start similar to this:
