I’m learning web development and I’m having a hard time learning about SSH, someone could explain me completely and already entering the theme explain me also what is the "Putty" related to all this?

  • SSH is a protocol, Putty is a client for you to connect to servers via SSH.

  • Your question is too broad. If you’re having trouble understanding even the basics of SSH, start by studying more basic things, like communication and protocols. In other words, your question is like "please explain black holes to me completely" and we could spend a few good months discussing it. I would recommend you to do the [tour] and read the [Ask] guide, then [Edit] your question and describe what your difficulties were. The answers currently given are basically what’s on Wikipedia and you’ve probably read earlier in your first search.

SSH (Secure Shell) is a protocol that allows you to virtually access the server as if you were in a terminal (in the DOS prompt, for example). If you prefer, consider as SSH as a computer controlling another computer.

The difference between telnet and SSH lies in security. All data transmission in SSH is encrypted. Thus, the risks of someone "snooping" what you are doing on the server (sometimes you need to transmit passwords to access other systems or programs) is virtually zero. Other than that, everything you do on telnet can be done by SSH.

When you connect via remote terminal with your server, you are controlling that server from your operating system. Any command you type runs on the server (and not on your PC) and you operate according to the server’s command parameters.

To access the SSH protocol you need a program that connects on port 22.

Here comes Putty who is the client for this connection

  • so from what I understand ssh is a terminal that allows me to communicate with a server "where this site used in my case that would refer to the web" safely, but I did not understand very well what is Putty .
