How to Generate an SSH Key Pair in Linux

SSH connections allow you to create secure connections between your device and a server. They rely on public-private key pairs for this to happen. The system offers greater security compared to credential-based access methods such as username and password.

The generation of SSH key pairs must be done on your device to create a set that matches your device. The process will differ slightly depending on the system used.

  • Step 1. Open a terminal window and type:

ssh-keygen -t rsa

  • Step 2. Enter the path where you wish to save the key. The default path is “/home/username/.ssh/id_rsa” – you can simply hit the enter key to accept this.
  • Step 3.  Enter your passphrase/password, then one more time to confirm that it is correct. 

You can locate the generated keys in the directory specified in Step 2 above. The public key should be uploaded to your server, while the private key should be embedded in your device.
