What is SSH

  • Secure Shell is the full form of SSH. So SSH uses encryption to enable secure connections to other devices, such as a server.
  • By using Secure SHell, your data, such as passwords, user names, etc., cannot be spied on.
  • SSH is not installed by default on computers running the Windows operating system. However, you can download free programs (SSH clients) with which you can use SSH. SSH is installed by default on current Linux and Apple Macintosh operating systems. If not, you can usually do this later.
  • SSH is the successor of Telnet. Telnet also sends data over the Internet. However, the data is sent un-encrypted, allowing third parties the potential of intercepting data.
