Struct elliptic_curve::secret_key::SecretKey

pub struct SecretKey<ScalarSize> where
    ScalarSize: ArrayLength<u8>,  { /* fields omitted */ }

Secret keys for Weierstrass curves: wrapper around scalar values used as secret keys.

Prevents accidental exposure and handles zeroization.

Methods

impl<ScalarSize> SecretKey<ScalarSize> where
    ScalarSize: ArrayLength<u8>, 

pub fn new(bytes: GenericArray<u8, ScalarSize>) -> Self

Create a new secret key from a serialized scalar value

pub fn from_bytes(bytes: impl AsRef<[u8]>) -> Result<Self, Error>

Deserialize this secret key from a bytestring

pub fn generate() -> Self

Generate a new secret key using the operating system's cryptographically secure random number generator

pub fn secret_scalar(&self) -> &Scalar<ScalarSize>

Expose the secret Scalar value this SecretKey wraps
