Password Entropy & NIST Strength Meter

Q: What is cryptographic entropy?

Entropy measures the unpredictability of a password in bits. A password with 80+ bits cannot be cracked by modern distributed supercomputer clusters.

Calculate bits of entropy, crack-time estimates against brute force clusters, and generate uncrackable cryptographically random passwords.
