ssh-keygen with a password

Creating a password-protected key looks something like this:

$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/pzhao/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/pzhao/.ssh/id_rsa.
Your public key has been saved in /home/pzhao/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:RXPnUZg/fGgRGTOxEfbo3VOMo/Yp4Gi80has/iR4m/A pzhao@localhost.localdomain
The key's randomart image is:
+---[RSA 3072]----+
|          o . %X.|
|         . o +=@ |
|          .   B++|
|         .   oo==|
|       .S . o...=|
|     . .oo o . ..|
|    o oo=.. . o  |
|     +o*o.   .   |

Notes: You may take advantage of GUI of RHEL to send Private Key as an email, then open the mail and copy the private key from email

Open the Notepad in Windows 10 and save private key as ansiblekey.pem file

Ansiblekey.pem

Then open PuTTY Key Generator and load the private key ansiblekey.pem

Load private key in putty key generator

Then save it as a private key as ansible.ppk file

We now open Putty and input IP address we saved previously as Host Name (or IP address) 192.168.0.18

Load private key in putty

We then move on to Session and input IP address
