SigningKey

lace_sans_io::records

Struct SigningKey 

pub struct SigningKey { /* private fields */ }
Expand description

A normalized secret derived from Lace’s 32-byte seed (not a raw scalar). Secret storage is erased on drop, best effort; compiler copies may remain.

Implementations§

§

impl SigningKey

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

pub fn verification_key(&self) -> VerificationKey

pub fn mark_digest( &self, digest: [u8; 32], aux: [u8; 32], ) -> Result<Mark, CryptoError>

Caller owns auxiliary randomness. Fixed values are allowed for vectors; fresh CSPRNG-generated bytes are recommended for ordinary signing.
