Struct exonum_crypto::SecretKey

pub struct SecretKey(_);

Ed25519 secret key used to create digital signatures over messages.

In public-key cryptography, the system uses a a mathematically related pair of keys: a public key, which is openly distributed, and a secret key, which should remain confidential. For more information, refer to Public-key cryptography.

Ed25519 is a signature system that ensures fast signing and key generation, as well as security and collision resilience.

Examples

In the example below, the function generates a pair of random public and secret keys.

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

Methods

impl SecretKey

pub fn zero() -> Self

Creates a new instance filled with zeros.

impl SecretKey

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

Creates a new instance from bytes array.

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

Creates a new instance from bytes slice.

pub fn to_hex(&self) -> String

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

Trait Implementations

impl PartialEq<SecretKey> for SecretKey

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

fn clone(&self) -> SecretKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for SecretKey
