Struct solana_zk_token_sdk::encryption::elgamal::ElGamalKeypair

pub struct ElGamalKeypair {
    pub public: ElGamalPubkey,
    pub secret: ElGamalSecretKey,
}

A (twisted) ElGamal encryption keypair.

The instances of the secret key are zeroized on drop.

Fields

public: ElGamalPubkey

The public half of this keypair.

secret: ElGamalSecretKey

The secret half of this keypair.

Implementations

impl ElGamalKeypair

pub fn new(signer: &dyn Signer, address: &Pubkey) -> Result<Self, SignerError>

Deterministically derives an ElGamal keypair from an Ed25519 signing key and a Solana address.

pub fn new_rand() -> Self

Generates the public and secret keys for ElGamal encryption.

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

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

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

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

Reads a JSON-encoded keypair from a Reader implementor

pub fn read_json_file<F: AsRef<Path>>(path: F) -> Result<Self, Box<dyn Error>>

Reads keypair from a file

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

Writes to a Write implementer with JSON-encoding

pub fn write_json_file<F: AsRef<Path>>(
    &self,
    outfile: F
) -> Result<String, Box<dyn Error>>

Write keypair to a file with JSON-encoding

Trait Implementations

impl Clone for ElGamalKeypair

fn clone(&self) -> ElGamalKeypair

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ElGamalKeypair

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ElGamalKeypair

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl PartialEq<ElGamalKeypair> for ElGamalKeypair

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for ElGamalKeypair

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 ElGamalKeypair

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.
