Crate qfall_schemes 

qFALL is a prototyping library for lattice-based cryptography. qFALL-schemes collects prototype implementations of lattice-based cryptography s.t. anyone can audit, modify, extend, or build on top of them to prototype more involved constructions or protocols. Among these are traits and implemented constructions of:

• Public-Key Encryption schemes implementations such as Regev’s Encryption, its dual version, LPR, or K-PKE,
• Signature schemes implementations such as GPV-based FDH or PFDH,
• an Identity-based Encryption from Dual Regev, as well as
• Hash functions such as the SIS hash or a SHA256-based hash.

The qFALL project contains two more crates called qFALL-math and qFALL-tools to support prototyping.

• Find further information on our website.
• We recommend our tutorial to start working with qFALL.

Quick Example

use qfall_schemes::pk_encryption::{KPKE, PKEncryptionScheme};
use qfall_math::integer::Z;

// setup public parameters
let k_pke = KPKE::ml_kem_512();

// generate (pk, sk) pair
let (pk, sk) = k_pke.key_gen();

// encrypt a message
let msg = Z::from_utf8("Hello");
let cipher = k_pke.enc(&pk, &msg);

// decrypt the ciphertext
let m = k_pke.dec(&sk, &cipher);

assert_eq!(msg, m);
