Architecture

neko (CLI)  ──IPC─►  nekod (Daemon)  ──LAN─►  peers
   localhost:54320           port:54322

The CLI never touches the network directly. Every LAN operation is handled by nekod, which runs as a background service.

Security

• Each installation generates a unique Node ID and an Ed25519 identity key pair.
• All sessions use X25519 ephemeral key exchange so traffic is encrypted with a fresh key each time.
• First-time connections show a 6-digit pairing code that must match on both devices.
• Once paired, devices are trusted automatically.

Configuration

OS	Path
Windows	%APPDATA%\NekoCat\
Linux	~/.config/nekocat/
macOS	~/Library/Application Support/NekoCat/

Config files:

• config.json — general settings
• trusted_peers.json — paired devices and their public keys
• nekocat.db — SQLite database for peer cache and all logs
