Struct chain_vote::cryptography::elgamal::SecretKey

pub struct SecretKey {
    pub sk: Scalar,
}

ElGamal secret key

Fields

sk: Scalar

Implementations

impl SecretKey

pub const BYTES_LEN: usize = 32usize

pub fn generate<R: RngCore + CryptoRng>(rng: &mut R) -> Self

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

pub(crate) fn recover_symmetric_key( &self, ciphertext: &HybridCiphertext ) -> SymmetricKey

pub(crate) fn hybrid_decrypt(&self, ciphertext: &HybridCiphertext) -> Vec<u8>

Decrypt a message using hybrid decryption

pub(crate) fn decrypt_point(&self, cipher: &Ciphertext) -> GroupElement

Decrypt ElGamal Ciphertext = (cipher.e1, cipher.e2), by computing cipher.e2 - self * cipher.e1. This returns the plaintext respresented as a GroupElement.

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.
