🔮 Quantum Resistance Estimate

Theoretical crack time analysis using Grover's algorithm

⚠️ Important Disclaimer: These quantum estimates are theoretical and educational only. Large-scale quantum computers capable of password cracking do not yet exist. These are future-proofing estimates, not current threats.

We apply Grover's algorithm modeling (quadratic speedup) to brute-force resistance calculations. We make no guarantee of accuracy in real-world quantum attack scenarios. Actual quantum cracking capabilities depend on hardware availability, error correction, coherence time, qubit count, and many other factors that remain uncertain. This is a theoretical model for educational and planning purposes.

📚 Understanding These Numbers

Classical attacks use GPUs/ASICs to try billions of passwords per second. Quantum attacks use Grover's algorithm, which provides a quadratic speedup (square root of search space). This means a password with 80 bits of classical security has approximately 40 bits of quantum security.

Important: Real-world quantum computers face significant overhead from error correction, coherence limitations, and circuit depth. Memory-hard password hashing (bcrypt, Argon2) further reduces quantum advantage. Use long, random passphrases and enable MFA for best security.
