Implementations

impl ElGamalCiphertext

pub fn add_amount<T: Into<Scalar>>(&self, amount: T) -> Self

pub fn subtract_amount<T: Into<Scalar>>(&self, amount: T) -> Self

pub fn to_bytes(&self) -> [u8; 64]

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

pub fn decrypt(&self, secret: &ElGamalSecretKey) -> DiscreteLog

Decrypts the ciphertext using an ElGamal secret key.

The output of this function is of type DiscreteLog. To recover, the originally encrypted message, use DiscreteLog::decode.

pub fn decrypt_u32(&self, secret: &ElGamalSecretKey) -> Option<u64>

Decrypts the ciphertext using an ElGamal secret key interpretting the message as type u32.
