Generate SSH KEY with ssh-keygen

1
ssh-keygen -t rsa -C "your_github_email@example.com"

Note : In local machines we may have multiple ssh keys, better to create the specific rsa. Example : Enter file in which to save the key (/home/ubuntu/.ssh/id_rsa): /home/ubuntu/.ssh/github_rsa

Generating public/private rsa key pair.
Enter file in which to save the key (/home/ubuntu/.ssh/id_rsa): /home/ubuntu/.ssh/github_rsa
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/ubuntu/.ssh/github_rsa.
Your public key has been saved in /home/ubuntu/.ssh/github_rsa.pub.
The key fingerprint is:
