🛡️ Why Flash512-Vanguard?

Standard encryption can be vulnerable if implemented incorrectly. Flash512-Vanguard provides a secure-by-default abstraction layer that combines:

Layer	Implementation	Standard
Primary KDF	Argon2id (memory-hard, GPU/ASIC resistant)	OWASP ASVS V2.4
Fallback KDF	PBKDF2-HMAC-SHA512 with 100,000 iterations	OWASP recommended
Authenticated Encryption	AES-256-GCM (128-bit tag)	NIST FIPS 197
Secure Nonce	Cryptographically random per operation	NIST SP 800-38D
Memory Protection	SecureBuffer with automatic wiping	Military-grade hygiene
Secret Management	Environment-based + Key Manager	SOC2 compliant

🔒 v2.1 Military Grade: Introduction d'Argon2id par défaut, SecureBuffer pour l'effacement mémoire automatique, et vérification d'intégrité du module au chargement (anti-tampering).

🚀 Key Features

• ✅ Polymorphic Output: Same message encrypted twice = different tokens (random nonce)
• ✅ Full Integrity: GCM authentication tag detects any tampering
• ✅ Key Rotation: Built-in rotate_secret() for password changes
• ✅ Audit Logging: Enterprise-ready audit trail (SOC2/HIPAA compatible)
• ✅ Memory Wiping: SecureBuffer efface automatiquement les données sensibles après usage
• ✅ Anti-Brute Force: Argon2id memory-hard KDF résiste aux GPU/ASIC
• ✅ Module Integrity: Vérification HMAC-SHA512 au chargement contre les modifications non autorisées
• ✅ Simple API: Méthodes protect() / open(), zero crypto expertise needed

📢 Official Release: Flash512-Vanguard Bastion v2.1

erabytse is proud to announce the launch of Flash512-Vanguard Bastion v2.1.

This Military Grade release introduces critical security hardening:

• 🔰 Argon2id : Dérivation de clé memory-hard pour résister aux attaques par force brute matérielles
• 🧹 SecureBuffer : Effacement automatique et garanti des données déchiffrées en mémoire
• 🛡️ Module Integrity : Vérification d'intégrité au chargement empêchant l'exécution de code modifié
• 🔒 Core Dump Lock : Désactivation automatique des core dumps sur Linux

The underlying industry-standard AES-256-GCM ensures:

• 🌍 Interoperability with other systems and languages
• 🔐 Auditability by third-party security firms
• ⚡ Performance via hardware acceleration (AES-NI)
• 📜 Compliance with NIST, FIPS, and enterprise security policies

The legacy v1.0 algorithm remains available via use_legacy=True for backward compatibility only.

🛡️ Vision

In an era of increasing cyber threats, we believe that encryption should be more than just a standard; it should be an evolving fortress. Flash512-Vanguard is our first step toward a suite of tools dedicated to Digital Sovereignty and Advanced Privacy.

Our commitment: Security through transparency, not obscurity. We use peer-reviewed standards so you can sleep at night.

💻 Quick Start

🔧 Installation v2.1

pip install flash512-vanguard==2.1.1

🔑 Configuration

Before using the engine, you must provision your Internal Core Secret. This secret acts as the unique architectural soul of your encryption.

On Linux/Mac:

export FLASH512_VANGUARD_CORE="your-secure-random-secret-64-chars-min"

On Windows (PowerShell):

$env:FLASH512_VANGUARD_CORE="your-secure-random-secret-64-chars-min"

Or create a .env file at your project root:

FLASH512_VANGUARD_CORE=your-secure-random-secret-64-chars-min

⚠️ Security Note: Never commit .env to version control. Add it to .gitignore.

📖 Usage Basic Encryption (Zero Expertise Required)

from flash512 import Flash512Vanguard

# Encrypt
token = Flash512Vanguard.protect("Classified Data", "MyUltraStrongSecret")
print(f"Secure Token: {token}")

# Decrypt
original = Flash512Vanguard.open(token, "MyUltraStrongSecret")
print(f"Decrypted: {original}")

# Verify without decrypting
if Flash512Vanguard.verify(token, "MyUltraStrongSecret"):
    print("Token is valid ✓")

# Rotate user password
new_token = Flash512Vanguard.rotate_secret(token, "OldPassword", "NewPassword")

Military Grade Decryption with SecureBuffer (v2.1+)

from flash512 import Flash512Vanguard

token = Flash512Vanguard.protect("Message Top Secret", "MotDePasse")

# Use the “with” context for automatic memory deallocation
with Flash512Vanguard.open(token, "MotDePasse") as buffer:
    # Process sensitive data ONLY within this protected block
    traiter_donnees_sensibles(buffer.data)
# Here, the data has already been cleared from the random access memory (RAM)
# Any attempt to access it will raise a RuntimeError

🧪 Testing

# Install dev dependencies
pip install -e .[dev]

# Run all tests (500+ random cases)
pytest tests/ -v

# Run military-grade specific tests
pytest tests/test_military_grade.py -v

# Run property-based tests
pytest tests/test_property.py -v
