Struct capycrypt::KeyPair

pub struct KeyPair {
    pub owner: String,
    pub pub_key: EdCurvePoint,
    pub priv_key: Vec<u8>,
    pub date_created: String,
    pub curve: EdCurves,
}

An object containing the fields necessary to represent an asymmetric keypair.

Fields

owner: String

String indicating the owner of the key, can be arbitrary

pub_key: EdCurvePoint

Public encryption key

priv_key: Vec<u8>

value representing secret scalar, None if KeyType is PUBLIC

date_created: String

Date key was generated

curve: EdCurves

Selected curve type

Implementations

impl KeyPair

pub fn new(pw: &Vec<u8>, owner: String, curve: EdCurves, d: u64) -> KeyPair

Asymmetric KeyPair Generation

Generates a (Schnorr/ECDHIES) key pair from passphrase pw.

Algorithm:

• s ← kmac_xof(pw, “”, 512, “K”); s ← 4s
• 𝑉 ← s*𝑮
• key pair: (s, 𝑉)

Arguments:

• pw: &Vec : password as bytes, can be blank but shouldnt be
• owner: String : A label to indicate the owner of the key
• curve: EdCurves : The selected Edwards curve

Returns:

• return -> KeyPair: Key object containing owner, private key, public key x and y coordinates, and timestamp. verification key 𝑉 is hashed together with the message 𝑚 and the nonce 𝑈: hash (𝑚, 𝑈, 𝑉) .

Usage:

use capycrypt::{
    curves::EdCurves::E448, KeyPair,
    sha3::{aux_functions::{byte_utils::{get_random_bytes}}}
};
// Get a random password
let pw = get_random_bytes(64);
let key_pair = KeyPair::new(&pw, "test key".to_string(), E448, 512);
