pq-web3-security

Protecting Web3 applications from current and future quantum threats.

Open-source Rust library and CLI tools for hybrid post-quantum cryptography, focused on Solana and Aptos ecosystems.

🎯 The Problem

Quantum computers pose a serious long-term threat to blockchain security:

• Shor's algorithm can break Ed25519 and secp256k1 signatures
• "Harvest Now, Decrypt Later" attacks are already happening
• Solana is adopting Falcon-512, but developers lack easy-to-use tools
• Aptos ecosystem lacks production-ready post-quantum solutions

✅ Our Solution

We build practical hybrid cryptographic tools combining classical and post-quantum algorithms (Falcon-512, Dilithium, etc.) to ensure crypto-agility and long-term security.

Key Features

• Hybrid signatures (Ed25519 + Falcon-512)
• Secure key generation and management
• Message & transaction signing / verification
• CLI tool for easy testing and integration
• High performance and memory safety (Rust)

🛠 Tech Stack

• Language: Rust 1.80+
• Cryptography: falconed (Ed25519 + Falcon-512)
• CLI: Clap
• CI/CD: GitHub Actions (fmt, clippy, tests, build)

🚀 Quick Start

# Clone the repository

git clone https://github.com/pissapisa500-debug/post-quantum-web3-security.git

cd post-quantum-web3-security


# Build the project

cargo build --release


# Generate hybrid keypair

cargo run --release -- generate --output mykey


# Sign a message

cargo run --release -- sign --key mykey.sk --message "Hello from post-quantum world"


# Verify signature

cargo run --release -- verify --pubkey mykey.pk --message "Hello from post-quantum world" --signature <signature_hex>
