Struct elgamal_curve25519::PrivateKey

pub struct PrivateKey(_);

PrivateKey is an ElGamal private key. It's just a wrapper around Scalar. The key is just an integer between 1 and q-1, where q is the order of the group G.

Methods

impl PrivateKey

pub fn new() -> Result<PrivateKey, String>

new creates a new random PrivateKey.

pub fn random() -> Result<PrivateKey, String>

random creates a random PrivateKey.

pub fn from_rng<R>(rng: &mut R) -> Result<PrivateKey, String> where
    R: RngCore + CryptoRng, 

from_rng creates a new random PrivateKey, but requires to specify a random generator.

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

from_hash creates a new PrivateKey from a 64 bytes hash.

pub fn from_scalar(scalar: Scalar) -> Result<PrivateKey, String>

from_scalar creates a new PrivateKey from a Scalar. The Scalar value cannot be 0.

pub fn to_scalar(&self) -> Scalar

to_scalar returns the inner Scalar of the PrivateKey.

pub fn from_bytes(buf: [u8; 32]) -> Result<PrivateKey, String>

from_bytes creates a new PrivateKey from a slice of bytes.

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

to_bytes returns the PrivateKey as an array of bytes.

pub fn to_public(&self) -> PublicKey

to_public returns the PublicKey of the PrivateKey.
