Information Entropy & NIST Cybersecurity Guidelines
According to the National Institute of Standards and Technology (NIST SP 800-63B), password strength is primarily determined by password length and entropy rather than complex periodic rotation requirements.
Entropy Benchmark Scales
| Entropy Range | Security Strength Rating | Brute Force Resilience |
|---|---|---|
| Under 40 bits | Very Weak | Cracked in seconds to minutes. |
| 40 – 60 bits | Moderate | Vulnerable to GPU cluster dictionary attacks. |
| 60 – 80 bits | Strong | Centuries of brute-force compute required. |
| Over 80 bits | Cryptographically Secure | Billions of years (virtually impossible to crack). |
