Struct HomomorphicElGamal 

pub struct HomomorphicElGamal { /* private fields */ }

Wrapper for ElGamal that enables operator overrides This allows using standard operators like +, -, *, / on ciphertexts

Implementations

impl HomomorphicElGamal

pub fn new(elgamal: ElGamal) -> Self

Create a new HomomorphicElGamal wrapper

pub fn inner(&self) -> &ElGamal

Get the underlying ElGamal instance

pub fn inner_mut(&mut self) -> &mut ElGamal

Get a mutable reference to the underlying ElGamal instance

pub fn encrypt(&self, plaintext: &BigUint) -> Result<Ciphertext>

Encrypt a plaintext

pub fn decrypt( &self, ciphertext: &Ciphertext, private_key: &PrivateKey, ) -> Result<BigUint>
