Struct cryptid::elgamal::PublicKey

pub struct PublicKey { /* fields omitted */ }

Implementations

impl PublicKey

pub fn new(value: CurveElem) -> Self

pub fn encrypt<R: Rng + CryptoRng>(
    &self,
    rng: &mut R,
    message: &[u8]
) -> Ciphertext

Encrypt a message. The message cannot have any trailing null (0u8) bytes, nor can it be over 32 bytes long

pub fn encrypt_curve(&self, m: &CurveElem, r: &Scalar) -> Ciphertext

pub fn rerand(self, ct: &Ciphertext, r: &Scalar) -> Ciphertext

Re-encrypt the ciphertext, replacing the random factors in the ciphertext with r. The encrypted message is the same, but an outside observer cannot tell that the two ciphertexts are related.
