Struct ControllerKeypair 

pub struct ControllerKeypair {
    pub id: String,
    /* private fields */
}

A controller’s long-term Ed25519 identity used across pairings.

id is the controller’s pairing identifier (iOSDevicePairingID) — an arbitrary UTF-8 string the accessory stores alongside the public key.

Fields

id: String

The controller’s pairing identifier.

Implementations

impl ControllerKeypair

pub fn generate(id: String) -> Self

Generate a fresh random Ed25519 keypair bound to id, using the operating system CSPRNG (OsRng).

pub fn from_seed(id: String, seed: [u8; 32]) -> Self

Reconstruct a keypair deterministically from a stored 32-byte Ed25519 seed bound to id.

Used by the test/replay harness and by persistence layers that store the raw seed. The same seed always yields the same keypair.

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

The controller’s long-term public key (LTPK): the 32-byte Ed25519 public key.

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

The controller’s 32-byte Ed25519 secret seed.

This is sensitive long-term private key material — the inverse of from_seed. It exists so a persistence layer (e.g. hap-pairing’s JsonFileStore) can save and later restore the controller identity. Store it only in a location you would treat as secret.

pub fn sign(&self, msg: &[u8]) -> [u8; 64]

Sign msg with the controller’s Ed25519 key, producing a 64-byte detached signature.

Trait Implementations

impl Clone for ControllerKeypair

fn clone(&self) -> ControllerKeypair

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for ControllerKeypair

impl PartialEq for ControllerKeypair

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
