Cryptographic Entropy & Diceware Password Mathematics
W3C Web Cryptography API random value generation with NIST SP 800-63B compliant password strength assessment.
Uses hardware entropy pools via `crypto.getRandomValues()` to guarantee cryptographically secure pseudo-randomness free from predictable pseudorandom modulo biases.
Diceware selects random words from vetted dictionaries. A 6-word phrase delivers 77 bits of entropy—practically impervious to brute-force cracking while easily memorized.
Your secrets are generated strictly inside local memory and immediately wiped on page unload. Zero passwords are ever sent across a network.
FREQUENTLY ASKED QUESTIONS
Q: How is crack time estimated?
Calculation assumes an offline attacker using specialized GPU clusters testing 100 billion combinations per second across the theoretical keyspace (`PoolSize ^ Length`).
Q: Is 128-bit entropy necessary for everyday accounts?
For master passwords, password managers, and SSH keys, 80+ bits is recommended. 128 bits matches AES-128 cryptographic key strength.
