Struct tari_crypto::ristretto::ristretto_keys::RistrettoSecretKey

pub struct RistrettoSecretKey(_);

The SecretKey implementation for Ristretto is a thin wrapper around the Dalek Scalar type, representing a 256-bit integer (mod the group order).

Creating secret keys

ByteArray and SecretKeyFactory are implemented for SecretKey(struct .SecretKey.html), so any of the following work (note that hex strings and byte array are little-endian):

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

let mut rng = rand::thread_rng();
let _k1 = RistrettoSecretKey::from_bytes(&[1,0,0,0, 0,0,0,0, 0,0,0,0, 0,0,0,0, 0,0,0,0, 0,0,0,0, 0,0,0,0, 0,0,0,0]);
let _k2 = RistrettoSecretKey::from_hex(&"100000002000000030000000040000000");
let _k3 = RistrettoSecretKey::random(&mut rng);

impl ByteArray for RistrettoSecretKey

fn from_bytes(bytes: &[u8]) -> Result<RistrettoSecretKey, ByteArrayError> where
    Self: Sized, 

Create a secret key on the Ristretto255 curve using the given little-endian byte array. If the byte array is not exactly 32 bytes long, from_bytes returns an error. This function is guaranteed to return a valid key in the group since it performs a mod l on the input.

fn as_bytes(&self) -> &[u8]

Return the byte array for the secret key in little-endian order

fn to_vec(&self) -> Vec<u8>

Return the type as a byte vector

fn from_vec(v: &Vec<u8>) -> Result<Self, ByteArrayError>

Try and convert the given byte vector to the implemented type. Any failures (incorrect string length etc) return a KeyError with an explanatory note.
