rust_checker

A modular Rust code validation tool with HTML, JSON, SVG badge, and JUnit XML report export.

Installation

cargo install rust_checker

Usage

rust_checker . --check-fmt --check-clippy

Post-Quantum Cryptography (PQC) Hybrid Example

Starting from version v1.0.1, rust_checker includes a real-world example demonstrating how to combine post-quantum key encapsulation (Kyber/ML-KEM) with classical symmetric encryption (ChaCha20-Poly1305) and key derivation (HKDF-SHA256) using production-grade Rust crypto libraries.

Overview

• Post-Quantum KEM: pqcrypto-kyber
• Key Derivation: ring::hkdf
• Symmetric AEAD: ring::aead::CHACHA20_POLY1305
• Secure RNG: rand::rngs::OsRng
• Zeroization: zeroize
• Constant-Time Comparison: subtle

Example Flow

1. Generate a Kyber keypair
2. Encapsulate/decapsulate to exchange a shared secret
3. Derive a symmetric key via HKDF-SHA256
4. Encrypt/decrypt a plaintext message with ChaCha20-Poly1305
5. Zeroize secrets on drop

Run the Example

cargo fmt --all
cargo test --all-features
cargo run --bin rust_checker -- --run-pqc-hybrid

##  Post-Quantum Cryptography (PQC) Hybrid Example

Starting from version **v1.0.1**, `rust_checker` includes a real-world example demonstrating how to combine **post-quantum key encapsulation (Kyber/ML-KEM)** with **classical symmetric encryption (ChaCha20-Poly1305)** and **key derivation (HKDF-SHA256)** using production-grade Rust crypto libraries.

###  Overview

- **Key Derivation:** [ring::hkdf](https://crates.io/crates/ring)
- **Symmetric AEAD:** [ring::aead::CHACHA20_POLY1305](https://crates.io/crates/ring)
- **Secure RNG:** [rand::rngs::OsRng](https://crates.io/crates/rand)
- **Zeroization:** [zeroize](https://crates.io/crates/zeroize)
- **Constant-Time Comparison:** [subtle](https://crates.io/crates/subtle)
