Generate an Ed25519 Key Pair

See more Ed25519 Examples

Demonstrates how to generate a new Ed25519 public/private key pair.

Note: This example requires Chilkat v9.5.0.83 or greater.

Rust

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

let eddsa = chilkat::EdDSA::new();
let prng = chilkat::Prng::new();
let priv_key = chilkat::PrivateKey::new();

// Generates a new eddsa key and stores it in privKey.
if eddsa.gen_ed25519_key(&prng, &priv_key).is_err() {
    println!("{}", eddsa.last_error_text());
    return;
}

// Examine the ed25519 key in JWK format;
let jwk = priv_key.get_jwk().unwrap_or_default();

let json = chilkat::JsonObject::new();
let _ = json.load(&jwk);
json.set_emit_compact(false);
println!("{}", json.emit().unwrap_or_default());

// 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.
