Struct signatory::ecdsa::SecretKey

pub struct SecretKey<C> where
    C: SecretValue + Curve,  { /* fields omitted */ }

Elliptic curve secret keys.

This type wraps a secret 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> SecretKey<C> where
    C: Curve + SecretValue,
    <C as SecretValue>::Secret: Clone,
    <C as SecretValue>::Secret: Zeroize,
    GenericArray<u8, <C as Curve>::FieldSize>: From<<C as SecretValue>::Secret>, 

pub fn new(secret_value: <C as SecretValue>::Secret) -> SecretKey<C>

Create a new secret key from a serialized scalar value

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

Deserialize this secret key from a bytestring

pub fn to_bytes(&self) -> GenericArray<u8, <C as Curve>::FieldSize>

Expose the byte serialization of the value this SecretKey wraps

Trait Implementations

impl<C> Clone for SecretKey<C> where
    C: SecretValue + Curve + Clone,
    <C as SecretValue>::Secret: Clone, 

pub 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> Debug for SecretKey<C> where
    C: Curve + SecretValue, 

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

Formats the value using the given formatter.

impl<C> Drop for SecretKey<C> where
    C: Curve + SecretValue, 

pub fn drop(&mut self)

Executes the destructor for this type.

impl<'_, C> TryFrom<&'_ [u8]> for SecretKey<C> where
    C: Curve + SecretValue,
    <C as SecretValue>::Secret: Clone,
    <C as SecretValue>::Secret: Zeroize,
    GenericArray<u8, <C as Curve>::FieldSize>: From<<C as SecretValue>::Secret>, 

type Error = Error

The type returned in the event of a conversion error.

pub fn try_from(slice: &[u8]) -> Result<SecretKey<C>, Error>

Performs the conversion.
