Struct commonware_cryptography::bls12381::scheme::Bls12381

pub struct Bls12381 { /* private fields */ }

BLS12-381 implementation of the Scheme trait.

This implementation uses the blst crate for BLS12-381 operations. This crate implments serialization according to the “ZCash BLS12-381” specification (https://github.com/supranational/blst/tree/master?tab=readme-ov-file#serialization-format) and hashes messages according to RFC 9380.

Implementations

impl Bls12381

pub fn new() -> Self

Creates a new Bls12381 signer using randomness from the operating system.

pub fn from(signer: [u8; 32]) -> Option<Self>

Creates a new Bls12381 signer from a secret key.
