Struct SecretKey 

pub struct SecretKey(/* private fields */);

An X25519 private key: 32 bytes, little-endian.

Stored unclamped; clamping (RFC 7748) is applied by the driver as part of the X25519 function. Zeroed on drop.

Implementations

impl SecretKey

pub fn generate() -> Result<Self, Error>

Generate a random private key from [driver::RngImpl].

pub fn from_bytes(bytes: &[u8; 32]) -> Self

Load a private key.

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

The private key bytes.

pub fn public_key(&self) -> Result<PublicKey, Error>

The corresponding public key.

pub fn diffie_hellman(&self, peer: &PublicKey) -> Result<SharedSecret, Error>

The shared secret with peer.

Fails with Error::InvalidKey if peer is a low-order point, which makes the shared secret all zeros (RFC 7748 section 6.1, required by TLS 1.3).

Trait Implementations

impl Clone for SecretKey

fn clone(&self) -> SecretKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SecretKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SecretKey

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
