X25519Key

issachar::classic::x25519

Struct X25519Key 

Source 
pub struct X25519Key { /* private fields */ }
Expand description

An ephemeral X25519 key pair for use in a single handshake.

Generate one with X25519Key::generate, read the public key with X25519Key::public_key_bytes, then call X25519Key::agree to perform the Diffie-Hellman step. agree consumes self; the underlying EphemeralSecret zeroizes the scalar on drop.

Implementations§

Source§

impl X25519Key

Source

pub fn generate() -> Self

Source

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

Source

pub fn agree(self, their_public: [u8; 32]) -> Result<[u8; 32], X25519Error>

Perform ECDH with their_public bytes, consuming self.

Returns Err when their_public is a low-order (non-contributory) point.
