Gangan

Gangan brings the ancient art of the talking drum into the digital age. Share confidential messages that only your trusted circle can read, protected by a cryptographic secret key that never leaves your devices. How it works: * Scramble: Type your message and encrypt it with a cipher key before sending over any channel. * Morse: Convert text to encrypted Morse code, shareable as text or audio. * Secure key exchange: Generate and exchange keys using Diffie-Hellman-Merkle, the same cryptography that secures the internet. Neither side ever sends the actual secret. For added security, your public key can be transmitted as an encoded Morse audio file — so even the key exchange stays off the grid. No accounts. No servers. No one in the middle. The key lives only on your device and expires automatically on a timer you control. Set up a secure channel with someone you trust. Then talk freely.
