croc

croc is a command-line utility that makes transferring files between computers simple and secure. It uses end-to-end encryption with password-authenticated key agreement (PAKE) to protect your data, ensuring only the sender and receiver can access transferred files.

Key capabilities include:

• Code phrase authentication: Generate or customize code phrases to securely establish connections between computers
• Multiple file transfers: Send individual files, folders, or multiple items in a single operation
• Resume interrupted transfers: Automatically resume transfers that were interrupted without starting over
• No infrastructure required: Works without needing a local server, port-forwarding, or complex setup
• Cross-platform support: Compatible with Windows, Linux, macOS, and even Android
• IPv6-ready: Supports modern IPv6 networks with automatic IPv4 fallback
• Proxy support: Route transfers through proxies like Tor for additional privacy
• Self-hosted relays: Run your own relay server for complete control over data routing
• Pipe support: Send data via stdin or receive to stdout for integration with other tools
• Text transfers: Quickly share URLs or short text snippets

Whether you're a sysadmin managing servers, a developer sharing code, or anyone needing to move files securely across machines, croc handles the encryption and connection details automatically. The simple code phrase approach eliminates the complexity of traditional file transfer methods while maintaining strong security standards.
