Struct PublicKey 

pub struct PublicKey { /* private fields */ }

X25519 Diffie-Hellman key exchange public key (RFC 7748).

Deserializing from bytes

use crypto::curve25519::x25519::PublicKey;

let bytes = [0u8; 32]; // replace with a peer's public key
let pub_key = PublicKey::from_bytes(&bytes);

Conversion from Ed25519

An Ed25519 PublicKey can be converted to an X25519 public key via TryFrom<&ed25519::PublicKey>.

Implementations

impl PublicKey

pub fn from_bytes(bytes: &[u8; 32]) -> Self

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

pub fn is_low_order(&self) -> bool

Returns true if this public key is a low-order point on Curve25519.

Low-order public keys are never produced by honest key generation. Passing one to SecretKey::ecdh produces an all-zero, publicly known shared secret, so it must be rejected or otherwise neutralized. The comparison is constant-time with respect to the key bytes.
