pub fn new_ed25519(bytes: [u8; 32]) -> Self

Constructs a new Ed25519 variant from a byte array.

pub fn new_secp256k1(bytes: [u8; 32]) -> Self

Constructs a new secp256k1 variant from a byte array.

pub fn ed25519_from_bytes<T: AsRef<[u8]>>(bytes: T) -> Result<Self>

Constructs a new Ed25519 variant from a byte slice.

pub fn secp256k1_from_bytes<T: AsRef<[u8]>>(bytes: T) -> Result<Self>

Constructs a new secp256k1 variant from a byte slice.

pub fn generate_ed25519() -> Self

Constructs a new Ed25519 variant using the operating system's cryptographically secure random number generator.

pub fn generate_secp256k1() -> Self

Constructs a new secp256k1 variant using the operating system's cryptographically secure random number generator.

pub fn as_secret_slice(&self) -> &[u8]

Exposes the secret values of the key as a byte slice.

pub fn to_file<P: AsRef<Path>>(&self, file: P) -> Result<()>

Attempts to write the secret key bytes to the configured file path.

pub fn from_file<P: AsRef<Path>>(file: P) -> Result<Self>

Trait Implementations

impl Clone for SecretKey

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for SecretKey

const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for SecretKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SecretKey

fn deserialize<D: Deserializer<'de>>(
    deserializer: D
) -> StdResult<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for SecretKey

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

Formats the value using the given formatter.

impl<'_> From<&'_ SecretKey> for PublicKey

fn from(secret_key: &SecretKey) -> PublicKey

Performs the conversion.

impl Loadable for SecretKey

type Error = Error

Error that can occur when attempting to load.

fn from_file<P: AsRef<Path>>(path: P) -> Result<Self, Self::Error>

Loads a value from the given input path.

impl Serialize for SecretKey

fn serialize<S: Serializer>(&self, serializer: S) -> StdResult<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
