Post-quantum file encryption using ML-KEM-768 + X25519

SecureVault - Post-Quantum File Encryption

Protect your files from future quantum computers.

The Problem

Quantum computers will break RSA/ECC encryption within 10-20 years. Attackers are stealing encrypted data NOW to decrypt LATER.

This is what we called "harvest now, decrypt later" attacks.

The Solution

SecureVault uses ML-KEM-768 (NIST standardized post-quantum crypto) in hybrid mode with X25519 for maximum security. Even if quantum computers break one layer, your data stays protected.

Features

• Hybrid encryption: X25519 + ML-KEM-768 (defense in depth²)
• Password-protected keys: PBKDF2 key derivation (100k iterations)
• Cross-platform: Works on Linux, macOS, and Windows
• Future-proof: Quantum-resistant for 30+ years
• Easy CLI: Simple commands, no crypto knowledge needed
• Educational: Shows security info about your files

Installation

Prerequisites

• Python 3.9 or higher
• pip

Setup

# Clone the repo
git clone https://github.com/yourusername/securevault.git
cd securevault

# Install dependencies
pip install -r requirements.txt

Quick Start

# 1. Generate your keypair
python3 secure_vault.py keygen --password mypassword --output my_keys.key
# Creates: my_keys.key (private) and my_keys_public.key (public)

# 2. Encrypt a file
echo "Secret data" > secret.txt
python3 secure_vault.py encrypt secret.txt my_keys_public.key

# 3. Check security info
python3 secure_vault.py info secret.txt.vault

# 4. Decrypt it
python3 secure_vault.py decrypt secret.txt.vault my_keys.key --password mypassword

Technical Details
