LetsMessageEncrypt

LetsMessageEncrypt is a privacy-focused mobile app that lets two people encrypt and decrypt text messages using a shared secret they agree on offline. There is no account, no server, and no cloud sync — keys and messages stay on your device.

You set up a named encryption key on each phone, verify both sides match with a fingerprint, then encrypt plaintext into base64 ciphertext you can send over SMS, email, chat, or any other channel. The other person pastes it in and decrypts it with the same key.

How it works
1. Create a key — Give it a name (e.g. “Test”) and a passphrase, or generate a random secret.
2. Share the key — Send the secret or fingerprint through a trusted channel, or show a QR code in person.
3. Import on the other device — Scan the QR or enter the name, secret, and fingerprint manually. The app checks the fingerprint before saving.
4. Encrypt & decrypt — Type a message, tap Encrypt, copy the ciphertext, and send it. On the other device, paste it and tap Decrypt.

The app is a tool for end-to-end-style privacy over channels you already use. It does not replace a messaging app; it adds encryption on top of whatever you use to deliver text.
