Type something secret, pick a Pass Key, and K8 turns it into gibberish you can paste into a text, an email, a DM — anywhere. Share the key with whoever you trust; everyone else just sees noise.
Three steps. No account, no app, no cost.
Type your message and choose a Pass Key only you and your reader know. Hit Scramble.
Copy the scrambled text and send it however you like — SMS, email, WhatsApp, a note. It's meaningless to anyone without the key.
Your reader pastes it into K8, switches to Unscramble, types the same Pass Key, and out pops your original message.
The same encryption governments use for top-secret files — done the modern way.
K8 uses the browser's built-in Web Crypto engine: AES-256-GCM with a key stretched from your Pass Key using 200,000 rounds of PBKDF2. Strong, standard, and tamper-evident.
There's no “encrypt” button that phones home. Your text and Pass Key are used right here on your device and never touch our servers — we couldn't read your messages if we wanted to.
No key, no message. Every scramble uses a fresh random salt and nonce, so the same text encrypted twice looks completely different.
K8 has been a free Transcom tool since the early days. No ads, no tracking, no sign-up — just a handy way to keep a message private.
Fun fact: brute-forcing one AES-256 message would take longer than the age of the Universe — many, many times over. Your Pass Key is the only weak link, so make it a good one. 🔑
