Made a small end-to-end encrypted chat tool. No accounts, no phone numbers, you just self-host an MQTT broker and share a key with someone. The part I think is actually useful: there's a clipboard mode where you type plaintext, it encrypts and copies to clipboard, then you paste the ciphertext into WeChat or email or whatever. The other person does the reverse. You don't even need to be using the same app. ChaCha20-Poly1305, Argon2id, Rust + Tauri, ~5MB exe. I know there are better tools for most threat models (Signal, Briar, SimpleX). This isn't trying to compete with them. It's for situations where you can't install a dedicated messenger or need to smuggle encrypted text through an existing channel. No forward secrecy, no traffic obfuscation, not audited, Windows only. All documented in the README. Unlicense. I won't maintain it. Fork it if it's useful to you.
