secp256k1 secret key.

Implementations

impl SecretKey

pub const SYSTEM_LENGTH: usize

The length in bytes of a system secret key.

pub const ED25519_LENGTH: usize

The length in bytes of an Ed25519 secret key.

pub const SECP256K1_LENGTH: usize

The length in bytes of a secp256k1 secret key.

pub fn ed25519(bytes: [u8; 32]) -> Self

Constructs a new Ed25519 variant from a byte array.

pub fn secp256k1(bytes: [u8; 32]) -> Self

Constructs a new secp256k1 variant from a byte array.

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

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

Trait Implementations

impl AsRef<[u8]> for SecretKey

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl AsymmetricType for SecretKey

fn system() -> Self

Constructs a new system variant.

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

Constructs a new ed25519 variant from a byte slice.

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

Constructs a new secp256k1 variant from a byte slice.

fn to_hex(&self) -> String

Converts the signature to hex, where the first byte represents the algorithm tag.

fn from_hex<A: AsRef<[u8]>>(input: A) -> Result<Self, Error>

Tries to decode a signature from its hex-representation. The hex format should be as produced by Signature::to_hex().

impl Clone for SecretKey

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for SecretKey where
    [u8; 32]: DataSize, 

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) -> Result<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 From<SecretKey> for PublicKey

fn from(secret_key: SecretKey) -> PublicKey

Performs the conversion.

impl FromBytes for SecretKey

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

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl Serialize for SecretKey

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

Serialize this value into the given Serde serializer.

impl Tagged<u8> for SecretKey

fn tag(&self) -> u8

Returns the tag of a given object

impl ToBytes for SecretKey

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error> where
    Self: Sized, 

Consumes self and serializes to a Vec<u8>.
