I want to transfer files securely between two computers using the Croc tool. How can I match the code expression given to me when I run the 'croc send [file_name]' command on the sender side with the 'croc [code_expression]' command on the receiving side and start the transfer? Is there a special setting I should pay attention to to ensure that end-to-end encryption is provided during the transfer and the process is secure?

Repository: https://github.com/schollz/croc. Follow the official instructions in the README of this repository for setup and execution.

Before starting, check which OS we are on and if the necessary tools (e.g., Python, Node.js, Git, Docker) are installed. Install any missing ones step-by-step according to this system.

Create a new, empty folder to work in. Do not touch any files outside this folder and do not delete anything. Tell me what you are going to do in one sentence before running each command.

Tell me what I should see on the screen at the end of each step. If an error occurs, I will paste the error message to you exactly as it is, and we will fix it together.
