Struct x25519_dalek::StaticSecret

pub struct StaticSecret(_);

A StaticSecret is a static Diffie-Hellman secret key that can be saved and loaded to create a SharedSecret when given their PublicKey.

Methods

impl StaticSecret

pub fn diffie_hellman(&self, their_public: &PublicKey) -> SharedSecret

pub fn new<T>(csprng: &mut T) -> Self where
    T: RngCore + CryptoRng,

pub fn to_bytes(&self) -> [u8; 32]

Save a x25519 StaticSecret key's bytes.
