Struct secp256k1::ecdh::SharedSecret

pub struct SharedSecret { /* fields omitted */ }

A tag used for recovering the public key from a compact signature

Methods

impl SharedSecret

pub fn capacity(&self) -> usize

Get the capacity of the underlying data buffer.

pub fn len(&self) -> usize

Get the len of the used data.

pub fn is_empty(&self) -> bool

True if the underlying data buffer is empty.

impl SharedSecret

pub fn new(point: &PublicKey, scalar: &SecretKey) -> SharedSecret

Creates a new shared secret from a pubkey and secret key

pub fn new_with_hash<F>(
    point: &PublicKey,
    scalar: &SecretKey,
    hash_function: F
) -> SharedSecret where
    F: FnMut([u8; 32], [u8; 32]) -> SharedSecret, 

Creates a new shared secret from a pubkey and secret key with applied custom hash function The custom hash function must be in the form of fn(x: [u8;32], y: [u8;32]) -> SharedSecret SharedSecret can be easily created via the From impl from arrays.

Examples

let secret = SharedSecret::new_with_hash(&public_key, &secret_key, |x,y| {
    let hash: [u8; 32] = sha2(&x,&y);
    hash.into()
});
