Struct elliptic_curve::secret_key::SecretKey

pub struct SecretKey<C: Curve> { /* fields omitted */ }

Elliptic curve secret keys.

This type wraps a serialized scalar value, helping to prevent accidental exposure and securely erasing the value from memory when dropped (when the zeroize feature of this crate is enabled).

Implementations

impl<C: Curve> SecretKey<C>

pub fn new(bytes: ElementBytes<C>) -> 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 as_bytes(&self) -> &ElementBytes<C>

Expose the byte serialization of the value this SecretKey wraps

Trait Implementations

impl<C: Clone + Curve> Clone for SecretKey<C>

fn clone(&self) -> SecretKey<C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C: Curve> Debug for SecretKey<C>

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

Formats the value using the given formatter.

impl<C: Curve> Drop for SecretKey<C>

fn drop(&mut self)

Executes the destructor for this type.

impl<C> Generate for SecretKey<C> where
    C: Curve + Arithmetic,
    C::Scalar: Generate + Into<ElementBytes<C>>, 

fn generate(rng: impl CryptoRng + RngCore) -> Self

This is supported on feature="rand" only.
