Offline tool that lets you encrypt short messages with AES-256, turn them into Morse code, and send them over radio using an arduino that makes beep every so ofter and then the pauses are counted in seconds or miliseconds and i the pause it how many times bigger than the set amount from the other person you take it as that many space's! (or any other way you transmit Morse).
The receiver pastes the Morse back in and decrypts it with the same password.
Important:
Never send the password over radio, text, email or any digital channel.
Share the password only in person — that's the whole point of the security model.
Check License before use! (shortened version is at the top of the file which is like 3 lines)
- You type a message
- It encrypts it with AES-256 (using the password you choose)
- Converts the encrypted data to hex → Morse code
- Adds "END" in Morse at the end
- You copy the Morse string and send it
- Other side pastes Morse → decrypts → gets original message back
- AES-256 encryption (CryptoJS)
- Hex encoding so Morse stays clean (no case problems)
- Light/dark mode
- Mobile friendly
- Warning popup about password sharing
- Optional quick tutorial on first visit
- Clone or download the repo
- Open

This tool is meant to work together with DIY 433 MHz / LoRa / PMR446 setups or even basic FM transmitters.
The Morse output is just text — you still need your own way to turn it into beeps/dots-dashes.
