Struct ElGamalCiphertext 

pub struct ElGamalCiphertext { /* private fields */ }

ElGamal ciphertext (c₁, c₂) where:

• c₁ = r*G (ephemeral public key)
• c₂ = mG + rH (encrypted message)

where H is the recipient’s public key

Implementations

impl ElGamalCiphertext

pub fn from_bytes(bytes: &[u8; 64]) -> ElGamalResult<Self>

Create an ElGamal ciphertext from compressed bytes (64 bytes: 32 for c1 + 32 for c2)

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

Export ciphertext to bytes

pub fn add(&self, other: &ElGamalCiphertext) -> ElGamalCiphertext

Homomorphic addition: E(m₁) + E(m₂) = E(m₁ + m₂)

pub fn mul_scalar(&self, scalar: u64) -> ElGamalCiphertext

Scalar multiplication: k * E(m) = E(k * m)

pub fn rerandomize(&self, public_key: &ElGamalPublicKey) -> ElGamalCiphertext

Re-randomize the ciphertext for unlinkability Returns a new ciphertext encrypting the same message but unlinkable to the original

Trait Implementations

impl Clone for ElGamalCiphertext

fn clone(&self) -> ElGamalCiphertext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElGamalCiphertext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ElGamalCiphertext

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ElGamalCiphertext

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ElGamalCiphertext

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
