LigmaSec

Light-weight, lattice-based post-quantum cryptographic library, designed to resist against attacks from both classical and quantum computers.

Usage

Add this to your Cargo.toml:

[dependencies]
ligmasec = "0.1.0"

or simply

cargo add ligmasec

Basic Example

use ligmasec::{LigmaSafety, SecurityLevel};

fn main() {
    // create a new instance with Standard security level
    let ligma = LigmaSafety::with_security_level(SecurityLevel::Standard);

    // generate keypair
    let (public_key, private_key) = ligma.generate_keypair().unwrap();

    // sign a message
    let message = b"hello, ligma balls!";
    let signature = ligma.sign(message, &private_key).unwrap();

    // verify the signature
    let is_valid = ligma.verify(message, &signature, &public_key).unwrap();
    assert!(is_valid);
}

Security Parameters

Security levels come with pre-configured parameters:

But dimensions can be increased for better security
