An end-to-end encrypted walkie-talkie for the command line
About
- A Bash-based walkie-talkie-style communication tool that exchanges voice and text over the Tor network anonymously with end-to-end encryption (E2EE)
- Connects directly to the other party using only a .onion address, with no server, account, or phone number; uses a push-to-talk (PTT) model where voice messages are recorded and then sent
- Provides strong security features: a choice of 21 ciphers including AES, ChaCha20, Camellia, and ARIA, HMAC-SHA256 authentication, PBKDF2 key derivation, and more
- Supports both Linux and Android Termux, and runs with only standard tools such as sox, opus-tools, Tor, and openssl
- Consists of a single script, so installation and maintenance are simple; usable for security research and privacy-focused communication experiments
