MensageiroSeguro is a small TCP messaging application: a command-line client connects to a relay, which manages user sessions and forwards opaque message payloads. The documented protocol also supports user listing and public-key registration and lookup; client-side encryption is not shown in the available source. The relay’s connection handling and state are visible, but the excerpt omits much of command dispatch, so those internal relationships are not inferred.
