Struct exonum::crypto::SecretKey

pub struct SecretKey(_);

Ed25519 secret key used to create digital signatures over messages.

Examples

use exonum::crypto;

let (_, secret_key) = crypto::gen_keypair();

Methods

impl SecretKey

pub fn zero() -> Self

Creates a new instance filled with zeros.

impl SecretKey

pub fn new(ba: [u8; 64]) -> Self

Creates a new instance from bytes array.

pub fn from_slice(bs: &[u8]) -> Option<Self>

Creates a new instance from bytes slice.

pub fn to_hex(&self) -> String

Returns the hex representation of the binary data. Lower case letters are used (e.g. f9b4ca).

Trait Implementations

impl Clone for SecretKey

fn clone(&self) -> SecretKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for SecretKey

fn eq(&self, __arg_0: &SecretKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &SecretKey) -> bool

This method tests for !=.

impl Eq for SecretKey

impl Debug for SecretKey

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

Formats the value using the given formatter.

impl ToHex for SecretKey

fn write_hex<W: Write>(&self, w: &mut W) -> Result

Writes the hex string representing self into w. Lower case letters are used (e.g. f9b4ca).

fn write_hex_upper<W: Write>(&self, w: &mut W) -> Result

Writes the hex string representing self into w. Upper case letters are used (e.g. F9B4CA).

impl FromHex for SecretKey

type Error = FromHexError

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

Creates an instance of type Self from the given hex string, or fails with a custom error type.

impl Serialize for SecretKey

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

Serialize this value into the given Serde serializer.

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

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

Deserialize this value from the given Serde deserializer.
