# Frontend: http://localhost:3000
# API: http://localhost:8000/docs
# Database: localhost:3306
🔐 Sécurité Post-Quantique
- Signatures: RSA-PSS + ML-DSA-65 (Dilithium) - FIPS 204
- Chiffrement: ML-KEM-768 (Kyber) + ElGamal - FIPS 203
- Hachage: SHA-256 (quantum-resistant)
- Approche hybride: Defense-in-depth
