Struct tari_crypto::ristretto::ristretto_keys::RistrettoPublicKey

pub struct RistrettoPublicKey { /* fields omitted */ }

The PublicKey implementation for ristretto255 is a thin wrapper around the dalek library's RistrettoPoint.

Creating public keys

Both PublicKey and ByteArray are implemented on RistrettoPublicKey so all of the following will work:

use tari_crypto::ristretto::{ RistrettoPublicKey, RistrettoSecretKey };
use tari_utilities::{ ByteArray, hex::Hex };
use tari_crypto::keys::{ PublicKey, SecretKey };
use rand;

let mut rng = rand::thread_rng();
let _p1 = RistrettoPublicKey::from_bytes(&[224, 196, 24, 247, 200, 217, 196, 205, 215, 57, 91, 147, 234, 18, 79, 58, 217,
144, 33, 187, 104, 29, 252, 51, 2, 169, 217, 154, 46, 83, 230, 78]);
let _p2 = RistrettoPublicKey::from_hex(&"e882b131016b52c1d3337080187cf768423efccbb517bb495ab812c4160ff44e");
let sk = RistrettoSecretKey::random(&mut rng);
let _p3 = RistrettoPublicKey::from_secret_key(&sk);
