SSH-Key generation process

Generate the ssh key using ssh-keygen using rsa algorithm as follows

[root@LinuxHelp ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase):
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:9OTtuEil8Hhcb7/RuHlf6d9IkBNwTqJMJPMCvntWkfE root@LinuxHelp
The key's randomart image is:
