Relay functionality of the croc command-line tool, which allows users to transfer data securely between devices without needing port forwarding. The relay server acts as an intermediary, facilitating connections even behind network address translation firewalls. Users can choose between public relays, custom relays, and different relay protocols, including TCP and WebSockets. For enhanced security, the croc tool uses PAKE encryption for relay connections. The text also details how to self-host a relay server for greater control and privacy, but this requires configuring a VPS with adequate bandwidth and ensuring regular maintenance and updates.
