Struct DeviceIdentity 

pub struct DeviceIdentity {
    pub device_id: [u8; 16],
    pub public_key: [u8; 32],
    /* private fields */
}

Device identity containing signing keys and derived key agreement keys

Fields

device_id: [u8; 16]

Device ID (BLAKE3-16 of Ed25519 public key)

public_key: [u8; 32]

Ed25519 public key for signatures

Implementations

impl DeviceIdentity

pub fn generate() -> Self

Generate a new random device identity

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

Create device identity from a seed (deterministic)

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

Sign data with this device’s Ed25519 key

pub fn x25519_public_key(&self) -> [u8; 32]

Get the X25519 public key for key agreement

pub fn agree(&self, remote_x25519_public: &[u8; 32]) -> Result<[u8; 32]>

Perform key agreement with a remote public key to derive a shared secret. Returns an error if the DH result is all-zero (low-order point).

pub fn pair_with( &self, remote_public_key: &[u8; 32], remote_x25519_public: &[u8; 32], ) -> Result<PairedDevice>

Pair with a remote device to create a PairedDevice

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

Export the identity seed (for backup/recovery)

Trait Implementations

impl Clone for DeviceIdentity

fn clone(&self) -> DeviceIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceIdentity

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

Formats the value using the given formatter.
