Small utilities for the everyday security work — rotating a password, sharing a credential safely, generating a strong passphrase. Everything runs in your browser, and I'm adding more over time.
Cryptographically random passwords via crypto.getRandomValues(). Defaults follow NIST 800-63B guidance for high-entropy machine-generated secrets.
Diceware-style passphrases — random words joined by a separator. Easier to type and remember; very strong with 4+ words.
Send a credential or short message as a self-contained link. AES-GCM encrypts the payload in your browser; the key lives in the URL fragment (the part after #), which never reaches the server. The recipient opens the link, the page decrypts client-side, and the plaintext is wiped from memory after viewing.
