croc

croc is a command-line tool designed for simple and secure file and folder transfers between any two computers. It uses a relay for connectivity and ensures end-to-end encryption through Password-Authenticated Key Exchange (PAKE). Key advantages include cross-platform compatibility, support for multiple files and folders, and the ability to resume interrupted transfers, all without requiring a local server or port forwarding. croc prioritizes IPv6 with IPv4 fallback and can work with proxies.
