Security Architecture

This layered design ensures that each stage of interaction—from interface to storage—operates under independent cryptographic protections.

Fun Fact: The Math Behind XColdPro Security #

Ever wondered how strong your ColdGuardian and BootVault software really are? Let’s break it down with some real-world math:

Entropy Sources #

• 256 bits of entropy from os.urandom + secrets.token_bytes
• scrypt (N=262144, r=8, p=1) → requires ~256MB RAM per attempt, making ASIC brute force painfully slow.
• AES-256-CBC → 2²⁵⁶ possible keys = ~10⁷⁷ combinations.
• HMAC-SHA256 → 2²⁵⁶ possible authentication values.
• Triple Memory Wipe → all sensitive data overwritten 3x for full erasure.
• PBKDF2 with 100,000+ iterations for password hardening.
• ed25519 keys → ~128-bit security level.
• secp256k1 private keys → full 256-bit strength.

Total Combined Entropy: well over 512 bits of effective cryptographic strength.

Hackability Timeline (Brute Force Estimates) #

• At a rate of 1 trillion attempts per second (10¹²/s):
• Cracking a single 256-bit AES key: 3.7 × 10⁶³ years
• With scrypt (262144 iterations): 9.7 × 10⁶⁸ years
• With PBKDF2 (100k rounds): 3.7 × 10⁶⁸ years
• With all layers combined: 10⁹³ years
• Perspective Check
• Age of the Universe: 1.4 × 10¹⁰ years
• Sun’s lifetime left: ~5 × 10⁹ years
• Heat Death of the Universe: 10¹⁰⁰ years
• Hackable time: well after the universe is gone.

✅ Fun takeaway: By the time someone brute-forces your ColdGuardian, the universe will have gone cold, dark, and silent.

Real-world cracking speeds (2025) #

High-end desktop (RTX 5090-class + AES-NI CPU)

Even granting an optimistic 1×10⁹ key guesses/second for raw AES-256:

• AES-256 brute force: ~1.8 × 10⁶⁰ years on average.
• With PBKDF2 (100k rounds): effective rate ÷100,000 → ~1.8 × 10⁶⁵ years.
• With scrypt (N=262,144, r=8, p=1): effective rate ÷262,144 → ~4.8 × 10⁶⁵ years.

A maxed-out gaming/workstation PC can’t make a dent. Memory-hard KDFs (like scrypt) multiply the pain by orders of magnitude.

“What about quantum?” (2025 reality) #

Grover’s algorithm gives a square-root speed-up, so AES-256 ~ 2¹²⁸ work in principle. But current quantum machines are nowhere near the qubits, fidelity, or error-correction required.

Even if you imagine a wildly generous 10¹² iterations/sec quantum box:

• Grover against AES-256: ~5.4 × 10¹⁸ years.
• At an utterly sci-fi 10¹⁸/sec: ~5.4 × 10¹² years.

With today’s (and foreseeable) quantum hardware, AES-256 remains far beyond reach. Grover reduces the exponent, not the problem.
