Implementations

source

impl ElGamalSecretKey

source

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.

source

pub fn new_rand() -> Self

Randomly samples an ElGamal secret key.

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

source

pub fn get_scalar(&self) -> &Scalar

source

pub fn decrypt(&self, ciphertext: &ElGamalCiphertext) -> DiscreteLog

Decrypts a ciphertext using the ElGamal secret key.

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

source

pub fn decrypt_u32(&self, ciphertext: &ElGamalCiphertext) -> Option<u64>

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

source

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

source

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

source

pub fn from_bytes(bytes: [u8 ; 32]) -> Option<ElGamalSecretKey>
