README.md

A minimal RedJubjub implementation for use in Zebra.

Two parameterizations of RedJubjub are used in Zcash, one for BindingSig and one for SpendAuthSig. This library distinguishes these in the type system, using the sealed SigType trait as a type-level enum.

In addition to the usual Signature, SecretKey, PublicKey types, the library also provides PublicKeyBytes, a refinement of a [u8; 32] indicating that bytes represent an encoding of a RedJubjub public key. This allows the PublicKey type to cache verification checks related to the public key encoding.

Examples

Creating a BindingSig, serializing and deserializing it, and verifying the signature:

# use std::convert::TryFrom;
use rand::thread_rng;
use redjubjub::*;

let msg = b"Hello!";

// Generate a secret key and sign the message
let sk = SecretKey::<Binding>::new(thread_rng());
let sig = sk.sign(thread_rng(), msg);

// Types can be converted to raw byte arrays using From/Into
let sig_bytes: [u8; 64] = sig.into();
let pk_bytes: [u8; 32] = PublicKey::from(&sk).into();

// Deserialize and verify the signature.
let sig: Signature<Binding> = sig_bytes.into();
assert!(
    PublicKey::try_from(pk_bytes)
        .and_then(|pk| pk.verify(msg, &sig))
        .is_ok()
);
