Struct Identity 

pub struct Identity { /* private fields */ }

A FIPS node identity consisting of a keypair and derived identifiers.

The identity holds the secp256k1 keypair and provides methods for signing and verifying protocol messages.

Implementations

impl Identity

pub fn generate() -> Identity

Create a new random identity.

pub fn from_keypair(keypair: Keypair) -> Identity

Create an identity from an existing keypair.

pub fn from_secret_key(secret_key: SecretKey) -> Identity

Create an identity from a secret key.

pub fn from_secret_bytes(bytes: &[u8; 32]) -> Result<Identity, IdentityError>

Create an identity from secret key bytes.

pub fn from_secret_str(s: &str) -> Result<Identity, IdentityError>

Create an identity from an nsec string (bech32) or hex-encoded secret.

pub fn keypair(&self) -> Keypair

Return the underlying keypair.

This is needed for cryptographic operations like Noise handshakes.

pub fn pubkey(&self) -> XOnlyPublicKey

Return the x-only public key.

pub fn pubkey_full(&self) -> PublicKey

Return the full public key (includes parity).

pub fn npub(&self) -> String

Return the public key as a bech32-encoded npub string (NIP-19).

pub fn node_addr(&self) -> &NodeAddr

Return the node ID.

pub fn address(&self) -> &FipsAddress

Return the FIPS address.

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

Sign arbitrary data with this identity’s secret key.

pub fn sign_challenge( &self, challenge: &[u8; 32], timestamp: u64, ) -> AuthResponse

Create an authentication response for a challenge.

The response signs: SHA256(“fips-auth-v1” || challenge || timestamp)

Trait Implementations

impl Debug for Identity

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

Formats the value using the given formatter.
