Generating a SSH key and use the result to log in to your Azure Linux VM is not that hard to accomplish.
In the following article I want to go over the steps.
You can use PuTTY to generate SSH keys. PuTTY is a free open-source terminal emulator that functions much like the Terminal application in macOS in a Windows environment.

May 05, 2019 To generate an SSH key pair on Windows using PuTTYgen perform the following steps: Start the PuTTYgen tool, by double-clicking on its.exe file or going to the Windows Start menu → PuTTY (64-bit) → PuTTYgen. For “Type of key to generate” leave the default RSA. The “Number of bits in a generated key”, 2048 is sufficient for most people. PuTTYgen is used to generate public or private key pair for creating SSH keys. Below is the complete guidance about how to generate RSA key in the Windows operating system: Once you install the PuTTY on your machine, you can easily run PuTTYgen. For the same, go to Windows - Start Menu - All Programs - PuTTY - PuTTYgen. Jan 12, 2015 This tutorial shows you how to quickly and easily create a pair of SSH Keys using PuTTYgen, one tool in the open source PuTTY suite. Install putty and generate ssh key to auto log in to Ubuntu.
Sep 26, 2019 Generating an SSH key. To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in the Key passphrase field. To generate a key with PuTTY, you should: Download and start the puttygen.exe generator. In the 'Parameters' section choose SSH2 DSA and press Generate. Move your mouse randomly in the small screen in order to generate the key pairs. Enter a key comment, which will identify the key (useful when you use several SSH keys).

First we need to download another “PuTTY” tool called PuTTY Key Generator.
Just download the PuTTYgen executable and start it.
Next you want to make sure that SSH-2 RSA is marked.
Hit “Generate” and make sure to move the mouse within the blank area of the application.
If your key is created you can optional set a passphrase (this would prompt you for a password on a login with your key). Also you want to save the private key (we need it later for PuTTY).
In the key field, select the hole content and copy it to the clipboard.
Login to Azure, select your VM, “All Settings” and “Reset password“. Enter a username (please mind the info box above the “User name” field) and select “SSH public key“. Insert your copied key into the text box and hit “Save“.
When your settings are saved, open PuTTY enter your login ip / url on the start form, then select “Connection -> SSH -> Auth” and hit “Browse …“.
Now select your saved private key and hit “Open“.
If everything worked out, PuTTY will ask for a username (optional your passphrase). Enter the username from the Azure Portal and you are logged in.
In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the ownership of a public key. The certificate includes information about the key, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer). How to generate intermediate and root cert from an existing leaf certificate? Ask Question. Now i have a X509 leaf certificate. From the certification path to see, there's a intermediate cert and a root cert in it. How to generate public certificate, private key from root certificate?
