Struct elgamal_curve25519::PublicKey

pub struct PublicKey(_);

PublicKey is an ElGamal public key. It's just a wrapper around CompressedRistretto. The key is computed as g^x, where g is the generator of the group G of order q, and x a PrivateKey.

Methods

impl PublicKey

pub fn new(private: PrivateKey) -> PublicKey

new creates a new PublicKey from a PrivateKey.

pub fn from_private(private: PrivateKey) -> PublicKey

from_private creates a new PublicKey from a PrivateKey.

pub fn random() -> Result<PublicKey>

random creates a new random PublicKey.

pub fn from_point(point: CompressedRistretto) -> PublicKey

from_point creates a new PublicKey from a CompressedRistretto.

pub fn to_point(&self) -> CompressedRistretto

to_point returns the inner CompressedRistretto of the PublicKey.

pub fn from_hash<D>(digest: D) -> PublicKey where
    D: Digest<OutputSize = U64> + Default, 

from_hash creates a new PublicKey from a 64 bytes hash.

pub fn from_bytes(buf: [u8; 32]) -> PublicKey

from_bytes creates a new PublicKey from a slice of bytes.

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

to_bytes returns the PublicKey as an array of bytes.
