Rust Requires Chilkat v11.0.0+

secp256k1 Key Generation and Keccak-256

See more ECC Examples

Starting in v11.0.0, Chilkat supports both secp256k1 key generation and Keccak-256 directly. These algorithms are typically used for Bitcoin and Ethereum. Rust

// This example 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 ECDSA 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 ECDSA private key on the secp256k1 curve.
let priv_key = chilkat::PrivateKey::new();
if ecc.gen_key("secp256k1", &fortuna, &priv_key).is_err() {
    println!("{}", ecc.last_error_text());
    return;
}

println!("Successfully generated a sec256k1 key.");

// Show how to compute the Keccak-256 hash in a few ways.
let sb = chilkat::StringBuilder::new();
let _ = sb.append("hello");

println!("keccak-256: {}", sb.get_hash("keccak-256", "hex_lower", "utf-8").unwrap_or_default());

// Output:
// keccak-256: 1c8aff950685c2ed4bc3174f3472287b56d9517b9c948127319a09a7a36deac8

// To keccak-256 hash binary data
let bd = chilkat::BinData::new();
let _ = bd.append_encoded("00010203040506", "hex");

println!("keccak-256: {}", bd.get_hash("keccak-256", "hex_lower").unwrap_or_default());

// Output:
// keccak-256: 801560412425120fa609be232d6fa71c7f64f42aee7977267687dcc0a2f5aa63
