Diceware-Style Passphrase Generator
Random word passphrases with real, calculated entropy
Diceware-Style Passphrase Generator creates random, memorable word-based passphrases using crypto.getRandomValues with proper rejection sampling — never Math.random — drawing from a curated ~4,096-word list. Choose 4 to 8 words, add an optional random number and separator, and see the exact calculated entropy in bits based on your real word count and list size, alongside an illustrative crack-time estimate.
