Struct EphemeralKeyPair 

pub struct EphemeralKeyPair { /* private fields */ }

An ephemeral X25519 keypair for one pair-session. Caller must persist the secret locally (we never put it on the wire) and publish the public via PairingRequested / PairingConfirmed.

When the pair ends, drop this struct (and any local copies of secret_hex) to honor forward secrecy.

Implementations

impl EphemeralKeyPair

pub fn generate() -> Self

Generate a fresh ephemeral keypair from the OS RNG. One per pair-session; do NOT reuse across pairs (no advantage, and any reuse weakens the forward-secrecy claim).

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

pub fn secret_hex(&self) -> String

32-byte secret as hex for local persistence. Endpoint implementations save this alongside their PairState; wipe the file when the pair is revoked.

pub fn public_hex(&self) -> String

pub fn from_secret_hex(s: &str) -> Result<Self>

Reconstruct from a secret hex string (matched output of secret_hex). Errors on bad hex or wrong length.

Trait Implementations

impl Debug for EphemeralKeyPair

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
