About:
Croc is a command-line tool that enables secure file transfers between computers using a simple six-character code. It multiplexes data through a public relay, allowing transfers to bypass firewalls and NATs without requiring port forwarding or complex configuration. The tool provides end-to-end encryption using PAKE to ensure that only the intended recipient can access the files.
Key Features:
  • Cross-platform file transfers without port forwarding
  • End-to-end encrypted connections using PAKE
  • Resumable transfers and direct peer-to-peer support
  • Simple, memorable code-based pairing
Use Cases:
  • Quickly sharing large files between devices on different networks
  • Securely transferring sensitive data without cloud storage
  • Automated file exchange in scripts and workflows
Alternatives:
  • scp – Requires SSH access and open ports; less convenient for ad-hoc transfers
  • rsync – Great for syncing but needs SSH setup and is not designed for simple one-off sharing
  • Magic Wormhole – Similar code-based transfer; croc offers built-in relays and P2P fallback
