How to Receive Large Files Using mkfifo and scp and Add id_rsa.pub to Authorized Keys

In today’s world, exchanging large files has become a common task. However, transferring large files securely can be a challenge, especially when dealing with sensitive data. In this blog, we will discuss how to receive large files using mkfifo and scp, and how to add id_rsa.pub to authorized keys for secure authentication.
