Load an Ed25519 Private Key from Hex

See more Ed25519 Examples

Demonstrates how to load an Ed25519 private key from raw hex bytes.

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 priv_key = chilkat::PrivateKey::new();

// We have the hexidecimal encoded bytes of the private key and public key:
let mut priv_key_hex = "d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842".to_string();
let pub_key_hex = "19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1".to_string();

// Load these values into the Chilkat private key object:
if priv_key.load_ed25519(&priv_key_hex, &pub_key_hex).is_err() {
    println!("{}", priv_key.last_error_text());
    return;
}

// ---------------------------------------------------------------
// We don't actually need the public key.  If we pass an empty string for the public key,
// Chilkat will automatically compute it.
let priv_key2 = chilkat::PrivateKey::new();
let _ = priv_key2.load_ed25519(&priv_key_hex, "").is_ok();

// Let's get the public key to see that it computed the same value.
let sb_pub_key_hex = chilkat::StringBuilder::new();
priv_key_hex = priv_key2.get_raw_hex(&sb_pub_key_hex).unwrap_or_default();
println!("computed public key = {}", sb_pub_key_hex.get_as_string().unwrap_or_default());

// The output should be:
// computed public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1
