Struct LocalKey 

pub struct LocalKey { /* private fields */ }

A private key held in memory, for tests and native tools. The browser never holds one: its wallet signs.

Implementations

impl LocalKey

pub fn from_bytes(secret: &[u8; 32]) -> Result<Self, SignError>

pub fn from_hex(secret: &str) -> Result<Self, SignError>

Thirty-two bytes of hex, 0x optional. A rejected key is never quoted back.

pub const fn address(&self) -> Address

pub fn sign_digest(&self, digest: &[u8; 32]) -> Result<Signature, SignError>

RFC 6979, so the same digest always signs the same; low-s.

Holds because SigningKey wipes itself; the assertion above checks that.
