How to generate an SSH Key Pair in Linux ?

 

Generate an SSH Key Pair in Linux 

[aaf@ip-10.0.0.0 ~]$

[aaf@ip-10.0.0.0 ~]$

[aaf@ip-10.0.0.0 ~]$

[aaf@ip-10.0.0.0 ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/aaf/.ssh/id_rsa):

Created directory '/home/aaf/.ssh'.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/aaf/.ssh/id_rsa

Your public key has been saved in /home/aaf/.ssh/id_rsa.pub

The key fingerprint is:

SHA256:mWZkHs4sTs3rue1E+9dQJXMN+imORLrDlh/IbJxNq4I aaf@ip-10.0.0.0.us-west-1.compute.internal

The key's randomart image is:

+---[RSA 3072]----+
