Entropy

Entropy measures the unpredictability of a password in bits. It's calculated as L × log₂(N) where L is the password length and N is the size of the character set used. Higher entropy = harder to guess.

Attack Models

Online: ~100 guesses/hour (rate-limited). GPU: ~1 billion guesses/sec (offline hash cracking). ASIC: ~1 quadrillion guesses/sec (specialized hardware). Times shown are worst-case (exhaustive search of keyspace).
