Struct EphemeralSecret 

pub struct EphemeralSecret(pub(crate) Array<u8, U56>);

An EphemeralSecret is a Scalar on Curve448.

Tuple Fields

0: Array<u8, U56>

Implementations

impl EphemeralSecret

pub fn new<R>(csprng: &mut R) -> Self

where R: CryptoRng + ?Sized,

👎Deprecated since 0.14.0: use the Generate trait instead

DEPRECATED: Generate a new ephemeral secret from the given RNG.

pub(crate) fn as_scalar(&self) -> Scalar<Ed448>

Views an Secret as a Scalar

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

Performs a Diffie-hellman key exchange between the secret key and an external public key

pub fn as_bytes(&self) -> &[u8; 56]

Converts a secret into a byte array

pub(crate) fn clamp(bytes: Array<u8, U56>) -> Self

Construct an EphemeralSecret by the secret key according to RFC7748.

Trait Implementations

impl Clone for EphemeralSecret

fn clone(&self) -> EphemeralSecret

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<&EphemeralSecret> for PublicKey

Given an EphemeralSecret Key, compute the corresponding public key using the generator specified in RFC7748

fn from(secret: &EphemeralSecret) -> PublicKey

Converts to this type from the input type.

impl Generate for EphemeralSecret

fn try_generate_from_rng<R>(csprng: &mut R) -> Result<Self, R::Error>

where R: TryCryptoRng + ?Sized,

Generate random key using the provided TryCryptoRng.

fn generate_from_rng<R>(rng: &mut R) -> Self

where R: CryptoRng + ?Sized,

Generate random key using the provided CryptoRng.

fn try_generate() -> Result<Self, Error>

Randomly generate a value of this type using the system’s ambient cryptographically secure random number generator.

fn generate() -> Self

Randomly generate a value of this type using the system’s ambient cryptographically secure random number generator.

impl Zeroize for EphemeralSecret

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
