//! BLS12-381 implementation of the `Scheme` trait.
//!
//! # Example
//! ```rust
//! use commonware_cryptography::{Bls12381, Scheme};
//! use rand::rngs::OsRng;
//!
//! // Generate a new private key
//! let mut signer = Bls12381::new(&mut OsRng);
//!
//! // Create a message to sign
//! let namespace = Some(&b"demo"[..]);
//! let msg = b"hello, world!";
//!
//! // Sign the message
//! let signature = signer.sign(namespace, msg);
//!
//! // Verify the signature
//! assert!(Bls12381::verify(namespace, msg, &signer.public_key(), &signature));
//! ```
