Rust Requires Chilkat v11.0.0+

Generate an ECDSA Key

See more ECC Examples

Demonstrates how to generate an ECDSA key. Rust

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

// Create a Fortuna PRNG and seed it with system entropy.
// This will be our source of random data for generating the ECC private key.
let fortuna = chilkat::Prng::new();
let entropy = fortuna.get_entropy(32, "base64").unwrap_or_default();
let _ = fortuna.add_entropy(&entropy, "base64").is_ok();

let ecc = chilkat::Ecc::new();

// Generate a random ECC private key on the secp256r1 curve.
// Chilkat also supports other curves, such as secp384r1, secp521r1, and secp256k1.

let priv_key = chilkat::PrivateKey::new();
if ecc.gen_key("secp256r1", &fortuna, &priv_key).is_err() {
    println!("{}", ecc.last_error_text());
    return;
}

println!("{}", priv_key.get_xml().unwrap_or_default());

// Save the private key to PKCS8 encrypted PEM
// (The private key can be saved in a variety of different formats. See the online reference documentation.)
if priv_key.save_pkcs8_encrypted_pem_file("pemPassword", "myPemFiles/eccKey123.pem").is_err() {
    println!("{}", priv_key.last_error_text());
}

println!("finished.");
