Schnorr

A Rust implementation of Schnorr key generation, signing, verification, multi-signatures and Key Aggregation.

We use a cyclic group G of prime order p, a generator of g of G, and a hash function H. In our case we are using the Ristretto Group as our curve.

Installation

To install, add the following to your project's Cargo.toml:

[dependencies.schnorr]
version = "0.0.1"

Then, in your library or executable source, add:

extern crate schnorr;

By default, schnorr builds against curve25519-dalek's u64_backend feature, which uses Rust's i128 feature to achieve roughly double the speed as the u32_backend feature. When targetting 32-bit systems, however, you'll likely want to compile with cargo build --no-default-features --features="u32_backend". If you're building for a machine with avx2 instructions, there's also the experimental avx2_backend. To use it, compile with RUSTFLAGS="-C target_cpu=native" cargo build --no-default-features --features="avx2_backend"
