Struct Keys 

pub struct Keys { /* private fields */ }

secp256k1 BIP-340 keypair.

Construct from a SecretKey (Keys::from_secret_key) or generate a fresh pair (Keys::generate). The public key is computed eagerly so signing has O(1) overhead.

Example

use nula_core::Keys;

let keys = Keys::generate().unwrap();
let pk_hex = keys.public_key().to_hex();
assert_eq!(pk_hex.len(), 64);

Implementations

impl Keys

pub fn from_secret_key(secret_key: SecretKey) -> Self

Construct a Keys from a SecretKey.

pub fn generate() -> Result<Self, SecretKeyError>

Generate a fresh Keys pair using the operating system’s entropy.

Errors

Returns SecretKeyError::Rng if the OS RNG fails.

pub fn parse<S>(input: S) -> Result<Self, SecretKeyError>

where S: AsRef<str>,

Parse Keys from a 64-char lowercase hex secret key.

Errors

See SecretKeyError.

pub const fn secret_key(&self) -> &SecretKey

Borrow the secret key.

pub const fn public_key(&self) -> &PublicKey

Borrow the public key.

pub const fn as_inner(&self) -> &Keypair

Borrow the inner secp256k1::Keypair.

Use this only at the boundary with the cryptography backend.

pub fn sign_schnorr(&self, message: &[u8; 32]) -> Signature

Sign an arbitrary message digest with BIP-340 Schnorr.

Callers are responsible for hashing application data — for Nostr events, the digest is the SHA-256 of the canonical serialization described in NIP-01.

Trait Implementations

impl Clone for Keys

fn clone(&self) -> Keys

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Keys

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

Formats the value using the given formatter.

impl Drop for Keys

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Eq for Keys

impl From<SecretKey> for Keys

fn from(secret_key: SecretKey) -> Self

Converts to this type from the input type.

impl NostrSigner for Keys

fn get_public_key(&self) -> SignerFuture<'_, Result<PublicKey, SignerError>>

Return the signer’s public key.

fn sign_event( &self, unsigned: UnsignedEvent, ) -> SignerFuture<'_, Result<Event, SignerError>>

Sign an UnsignedEvent and return the resulting Event.

fn nip04_encrypt<'a>( &'a self, peer: &'a PublicKey, plaintext: &'a str, ) -> SignerFuture<'a, Result<String, SignerError>>

NIP-04 (legacy) encrypt to peer.

fn nip04_decrypt<'a>( &'a self, peer: &'a PublicKey, ciphertext: &'a str, ) -> SignerFuture<'a, Result<String, SignerError>>

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

Inequality operator !=.
