pub struct X25519;

Expand description

An implementation of X25519 Elliptic-curve Diffie-Hellman (ECDH) cryptographic key exchange.

Implementations

source

impl X25519

source

pub const PRIVATE_KEY_LENGTH: usize = 32usize

Length in bytes of an X25519 private key.

source

pub const PUBLIC_KEY_LENGTH: usize = 32usize

Length in bytes of an X25519 public key.

source

pub fn key_exchange<PRV, PUB>(
 private: &PRV,
 public: &PUB
) -> Result<[u8 ; 32], Error> where
 PRV: AsRef<[u8]> + ?Sized,
 PUB: AsRef<[u8]> + ?Sized,

Performs Diffie-Hellman key exchange using the private key of the first party with the public key of the second party, resulting in a shared secret.

source

pub fn ed25519_to_x25519_private<PRV>(
private_key: &PRV
) -> Result<Key<Private>, Error> where
PRV: AsRef<[u8]> + ?Sized,

Transforms an Ed25519 private key to an X25519 private key.

This is possible because Ed25519 is birationally equivalent to Curve25519 used by X25519.

source

pub fn ed25519_to_x25519_public<PUB>(
public_key: &PUB
) -> Result<Key<Public>, Error> where
PUB: AsRef<[u8]> + ?Sized,

Transforms an Ed25519 public key to an X25519 public key.

This is possible because Ed25519 is birationally equivalent to Curve25519 used by X25519.
