Generate Ssh Keys Linux Rsa

How do I generate ssh RSA keys under Linux operating systems?
You need to use the ssh-keygen command as follows to generate RSA keys (open terminal and type the following command):
ssh-keygen -t rsa
Sample outputs:


SiteGround uses key-based authentication for SSH. This has proven more secure over standard username/password authentication. More information on SSH keys can be found here. You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account. These instructions are for the PuTTY terminal emulator. It is possible to login with other clients but you're on your own in figuring out how to generate SSH keys. Download and install PuTTY and friends. I recommend the 32-bit or 64-bit MSI 'Windows Installer' as that will include all of the utilities needed to generate and manage SSH keys.

The -t type option specifies the type of key to create. The possible values “rsa” or “dsa” for protocol version 2. The $HOME/.ssh stores the following two files:

  • $HOME/.ssh/id_rsa – Your private RSA key
  • $HOME/.ssh/ – Your public RSA key

Please do not share keys file with anyone else. You can upload keys to remote server as follows:
ssh-copy-id [email protected]
Finally, you can login to remote server as follows:
ssh [email protected]
scp file.txt [email protected]:~/data2/
