Struct ElGamalPubkey

pub struct ElGamalPubkey(/* private fields */);

Public key for the ElGamal encryption scheme.

Implementations

impl ElGamalPubkey

pub fn new(secret: &ElGamalSecretKey) -> Self

Derives the ElGamalPubkey that uniquely corresponds to an ElGamalSecretKey.

pub fn get_point(&self) -> &RistrettoPoint

pub fn to_bytes(&self) -> [u8; 32]

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

pub fn encrypt<T: Into<Scalar>>(&self, amount: T) -> ElGamalCiphertext

Encrypts an amount under the public key.

This function is randomized. It internally samples a scalar element using OsRng.

pub fn encrypt_with<T: Into<Scalar>>( &self, amount: T, opening: &PedersenOpening, ) -> ElGamalCiphertext

Encrypts an amount under the public key and an input Pedersen opening.

pub fn decrypt_handle(self, opening: &PedersenOpening) -> DecryptHandle

Generates a decryption handle for an ElGamal public key under a Pedersen opening.

Trait Implementations

impl Clone for ElGamalPubkey

fn clone(&self) -> ElGamalPubkey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ElGamalPubkey

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

Formats the value using the given formatter.

impl Default for ElGamalPubkey

fn default() -> ElGamalPubkey

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ElGamalPubkey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ElGamalPubkey

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

Formats the value using the given formatter.

impl EncodableKey for ElGamalPubkey

fn read<R: Read>(reader: &mut R) -> Result<Self, Box<dyn Error>>

fn write<W: Write>(&self, writer: &mut W) -> Result<String, Box<dyn Error>>

impl From<ElGamalPubkey> for ElGamalPubkey

fn from(decoded_pubkey: ElGamalPubkey) -> Self

Converts to this type from the input type.

impl PartialEq for ElGamalPubkey

fn eq(&self, other: &ElGamalPubkey) -> 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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<ElGamalPubkey> for ElGamalPubkey

type Error = ElGamalError

The type returned in the event of a conversion error.

fn try_from(pod_pubkey: ElGamalPubkey) -> Result<Self, Self::Error>

Performs the conversion.

impl Zeroize for ElGamalPubkey

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.
