Struct tor_hsservice::internal_prelude::curve25519::EphemeralSecret

pub struct EphemeralSecret(pub(crate) [u8; 32]);
Expand description

A short-lived Diffie-Hellman secret key that can only be used to compute a single SharedSecret.

This type is identical to the StaticSecret type, except that the EphemeralSecret::diffie_hellman method consumes and then wipes the secret key, and there are no serialization methods defined. This means that EphemeralSecrets can only be generated from fresh randomness where the compiler statically checks that the resulting secret is used at most once.

Implementations§

§

impl EphemeralSecret

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

Perform a Diffie-Hellman key agreement between self and their_public key to produce a SharedSecret.

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

👎Deprecated since 2.0.0: Renamed to random_from_rng. This will be removed in 2.1.0

Generate a new EphemeralSecret with the supplied RNG.

pub fn random_from_rng<T>(csprng: T) -> EphemeralSecret
where T: RngCore + CryptoRng,
