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

bool success;
success = rsa.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show("RSA component unlock failed");
    return;
}

//  Generate a 1024-bit key.  Chilkat RSA supports
//  key sizes ranging from 512 bits to 4096 bits.
success = rsa.GenerateKey(1024);
if (success != true) {
    MessageBox.Show(rsa.LastErrorText);
    return;
}

//  Keys are exported in XML format:
string publicKeyXml;
publicKeyXml = rsa.ExportPublicKey();
textBox1.Text += publicKeyXml + "\r\n";

string privateKeyXml;
privateKeyXml = rsa.ExportPrivateKey();
textBox1.Text += privateKeyXml + "\r\n";

//  Save the private key in PEM format:
Chilkat.PrivateKey privKey = new Chilkat.PrivateKey();
privKey.LoadXml(privateKeyXml);
privKey.SaveRsaPemFile("privateKey.pem");

//  Save the public key in PEM format:
Chilkat.PublicKey pubKey = new Chilkat.PublicKey();
pubKey.LoadXml(publicKeyXml);
pubKey.SaveOpenSslPemFile("publicKey.pem");
