Struct x25519_dalek::StaticSecret
source · pub struct StaticSecret(/* private fields */);
Expand description
A Diffie-Hellman secret key that can be used to compute multiple SharedSecret
s.
This type is identical to the EphemeralSecret
type, except that the
StaticSecret::diffie_hellman
method does not consume the secret key, and the type provides
serialization methods to save and load key material. This means that the secret may be used
multiple times (but does not have to be).
§Warning
If you’re uncertain about whether you should use this, then you likely
should not be using this. Our strongly recommended advice is to use
EphemeralSecret
at all times, as that type enforces at compile-time that
secret keys are never reused, which can have very serious security
implications for many protocols.
Implementations§
source§impl StaticSecret
impl StaticSecret
sourcepub fn diffie_hellman(&self, their_public: &PublicKey) -> SharedSecret
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
.

. This will be removed in 2.1.0
pub fn new<T: RngCore + CryptoRng>(csprng: T) -> Self
random_from_rng
. This will be removed in 2.1.0Generate a new StaticSecret
with the supplied RNG.
sourcepub fn random_from_rng<T: RngCore + CryptoRng>(csprng: T) -> Self
pub fn random_from_rng<T: RngCore + CryptoRng>(csprng: T) -> Self
