Croc

Croc is a command-line tool designed for secure file transfer between computers. It was developed by Rob Landley and is known for its simplicity and ease of use. The tool uses a unique approach to file transfer by leveraging the SSH protocol, which ensures that files are transmitted securely and encrypted. Croc can be used to transfer files between different operating systems, including Windows, macOS, and Linux, making it a versatile tool for various environments.

To use Croc, users need to have SSH access to the destination computer. The process involves running a command on the sending computer to initiate the transfer, which generates a unique code. This code is then used on the receiving computer to accept the file transfer. The tool supports various file types and can handle large files efficiently. Croc is particularly useful for scenarios where traditional file transfer methods may be impractical or insecure, such as transferring files between different networks or across the internet.

Croc is open-source software, and its source code is available on platforms like GitHub. This allows users to inspect the code, contribute to its development, and customize it to meet specific needs. The tool is designed to be user-friendly, with a straightforward command-line interface that requires minimal configuration. Despite its simplicity, Croc provides robust security features, making it a reliable choice for secure file transfers.
