Generate Encryption Passphrases
For full-disk encryption, GPG keys, or any cryptographic system that needs a memorable secret.
...
Why diceware? Memorable phrases of random words have huge entropy and are easier to remember than gibberish like “X#9mP$qZ”. A 5-word phrase has more entropy than a 10-character random password with mixed case + symbols.
🔒 All randomness comes from crypto.getRandomValues() in your browser. No words, passphrases, or any data are sent anywhere.
Encryption tips
LUKS, FileVault, BitLocker — all benefit from a strong recovery passphrase. Diceware makes one you can recover by writing words down individually.
For GPG/PGP keys: a 5-7 word diceware phrase is industry-standard. The "use random words" pattern is documented in cryptocurrency wallet recovery as well (BIP-39).
Print the phrase on paper, split it across two physical locations (e.g., 4 words at home, 3 at the office). Even thieves can't reassemble it.
