Zuer

This library provides implementations of prime fields and elliptic curve operations in Rust. In the future, it will also include lattice-based cryptography, signatures, and symmetric/asymmetric cryptography.

File Structure

• src/lib.rs: Contains the core traits and structs, including the PrimeField trait and the Fe struct for representing field elements.
• src/curves.rs: Defines specific prime fields, such as BN254 and SmallPrime, and implements the PrimeField trait for them. It also includes unit tests for field element conversions and addition.
• src/point.rs: Defines the Point struct for representing points on an elliptic curve and implements basic point operations like addition.

Usage

To use this library, add the following to your Cargo.toml file:

[dependencies]
zuer = { git = "https://github.com/hhamud/zuer" }

Here's a basic example of how to use the library:

use zuer::{Fe, SmallPrime};

fn main() {
    let a: Fe<SmallPrime> = 5u64.into();
    let b: Fe<SmallPrime> = 10u64.into();
    let c = a + b;

    println!("a: {}", a.value());
    println!("b: {}", b.value());
    println!("c: {}", c.value());
}

Testing

The src/curves.rs file includes unit tests for basic field operations. To run the tests, use the following command:

cargo test
