bool success = false;

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

Chilkat.EdDSA eddsa = new Chilkat.EdDSA();
Chilkat.Prng prng = new Chilkat.Prng();
Chilkat.PrivateKey privKey = new Chilkat.PrivateKey();

//  Generates a new eddsa key and stores it in privKey.
success = eddsa.GenEd25519Key(prng,privKey);
if (success == false) {
    Debug.WriteLine(eddsa.LastErrorText);
    return;
}

//  Examine the ed25519 key in JWK format;
string jwk = privKey.GetJwk();

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.Load(jwk);
json.EmitCompact = false;
Debug.WriteLine(json.Emit());

//  Sample output:
//  {
//    "kty": "OKP",
//    "crv": "Ed25519",
//    "x": "SE2Kne5xt51z1eciMH2T2ftDQp96Gl6FhY6zSQujiP0",
//    "d": "O-eRXewadF0sNyB0U9omcnt8Qg2ZmeK3WSXPYgqe570",
//    "use": "sig"
//  }

//  In the above JWK, x is the public key, y is the private key.
//  Both are 32 bytes and are base64-url encoded.
