C# example code showing how to generate an RSA public/private key pair and export to PEM files.

Note: This example requires Chilkat v11.0.0 or greater.

bool success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

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

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

Chilkat.PublicKey pubKey = new Chilkat.PublicKey();
privKey.ToPublicKey(pubKey);

// Save the private key in PEM format:
success = privKey.SavePemFile("privateKey.pem");
if (success == false) {
    Debug.WriteLine(privKey.LastErrorText);
    return;
}

// Save the public key in PEM format:
success = pubKey.SavePemFile(false,"publicKey.pem");
if (success == false) {
    Debug.WriteLine(pubKey.LastErrorText);
    return;
}

Debug.WriteLine("Success.");
