Diceware Passphrase Generator

Generate strong, memorable passphrases by sampling words uniformly at random from the EFF Diceware wordlists — the EFF long list (7776 words, rolled with five dice) or one of the two short lists (1296 words, four dice). The random indices use the Web Crypto API (crypto.getRandomValues with rejection sampling), so each word is drawn uniformly from the wordlist — no modulo bias. Choose the number of words, separators, capitalization, optional digits/symbols, and copy the result. Everything runs locally in your browser — your passphrase never leaves the page.
