How it works. Diceware uses dice rolls to pick words from a wordlist. With 7,776 words, each word contributes log₂(7776) ≈ 12.9 bits of entropy. This page uses crypto.getRandomValues instead of physical dice; the rolled indices are still shown for transparency. The wordlist is the EFF large list. Recommended: at least 6 words for good personal security.
