Struct schnorr_fun::KeyPair

pub struct KeyPair { /* fields omitted */ }

A secret and public key-pair for generating Schnorr signatures.

The KeyPair struct is exists because it is more efficient to pre-compute the public key and pass it in rather pass it in when signing with the same key multiple times.

Create a KeyPair from a Schnorr instance.

let my_secret_key = Scalar::random(&mut rand::thread_rng());
let my_keypair = schnorr.new_keypair(my_secret_key);

Implementations

impl KeyPair

pub fn secret_key(&self) -> &Scalar

Returns a reference to the secret key.

pub fn public_key(&self) -> &XOnly

Returns a reference to the public key.

pub fn as_tuple(&self) -> (&Scalar, &XOnly)

Gets a reference to the key-pair as a tuple

Example

let (secret_key, public_key) = keypair.as_tuple();

pub fn verification_key(&self) -> Point<EvenY>

Returns the full Point<EvenY> for the public key which is used in verify.

This is just a descriptive short version of:

let verification_key = keypair.public_key().to_point();
