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
