Struct libpaillier::EncryptionKey

pub struct EncryptionKey { /* private fields */ }

A Paillier encryption key

Implementations

impl EncryptionKey

pub fn encrypt<M>(&self, x: M, r: Option<Nonce>) -> Option<(Ciphertext, Nonce)>

where M: AsRef<[u8]>,

Encrypt a given message with the encryption key and optionally use a random value x must be less than N

pub fn add(&self, c1: &Ciphertext, c2: &Ciphertext) -> Option<Ciphertext>

Combines two Paillier ciphertexts commonly denoted in text as c1 \bigoplus c2

pub fn mul(&self, c: &Ciphertext, a: &BigNumber) -> Option<Ciphertext>

Equivalent to adding two Paillier exponents

pub fn to_bytes(&self) -> Vec<u8>

Get this key’s byte representation

pub fn from_bytes<B: AsRef<[u8]>>(data: B) -> Result<Self, String>

Convert a byte representation to a encryption key

pub fn from_n(n: BigNumber) -> Self

Constructs encryption key from the Paillier modulus

pub fn n(&self) -> &BigNumber

The Paillier modulus

pub fn nn(&self) -> &BigNumber

The Paillier modulus squared

Trait Implementations

impl Clone for EncryptionKey

fn clone(&self) -> EncryptionKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EncryptionKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EncryptionKey

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&DecryptionKey> for EncryptionKey

fn from(sk: &DecryptionKey) -> EncryptionKey

Converts to this type from the input type.

impl Serialize for EncryptionKey

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Zeroize for EncryptionKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
