SSH is a protocol that allows you to communicate with a machine securely.

When I first used SSH I thought it was simply a way to open a shell like telnet and have the communications encrypted. I soon learned it was more than that.

Here's a list of things SSH can do for you:

  • Establish an encrypted shell between 2 machines
  • Securely copy files between 2 machines
  • Use keys so you don't have to type your password everytime you log in or copy a file.
  • Port forward insecure protocols over SSH
