Or, if you have already created a cloud instance using the new ppk format (version 3), the best option is to change the format of that key and convert it to the (old) version 2. Click Save private key, to save the key with the old ppk format. This option is better if you are just creating the cloud instance.Ĭlick on Generate a public or public key pair, click on Generate. You will be able to SSH to the cloud instance. Step 2: Generate a new SSH key pair or change the format of an existing one.Īfter following step one, you can now generate a key using the ppk version 2. Go to Key > Parameters for saving key files.Ĭhange the PuTTygen PPK File Version to version 2. Step 1: Change the PuTTygen PPK File Version to version 2. You can generate a new SSH key pair or change the private key format of an existing private key using PuTTygen. Soon all SSH and FTTP programs should support the latest version of PuTTy. So a quick workaround is to change to one of these programs. I tested the newest version of the programs to date. Other programs already use the latest ppk version 3, such as WinSCP, FileZilla, WinSSHTerm (here, the main SSH program is PuTTy), and others. Note that this is not a problem for PuTTY itself. Problem Couldn't load private key - Putty key format too newĪttempting to SSH a cloud instance, you get this (or a similar) message: To connect to a remote machine with PuTTY, your private key should have a ppk format. You need to convert the private key to the PuTTY required format. However, PuTTY doesn't support the SSH private key format created by the Oracle Cloud wizards. For example, in Oracle Compute Cloud Service, you must generate your SSH key pair and upload the SSH public key before creating your instance. When you create a compute instance, you must provide an SSH public key that will be used for authentication when you log in to the instance. Currently, it is still extremely popular to access cloud instances. Functionally SSH keys resemble passwords, granting access and control to who can access what. It is also inside many file transfer tools and configuration management tools. Enter the username from the Azure Portal and you are logged in.SSH SSH (Secure Shell) is used for managing networks, operating systems, and configurations. If everything worked out, PuTTY will ask for a username (optional your passphrase). Now select your saved private key and hit “ Open“. When your settings are saved, open PuTTY enter your login ip / url on the start form, then select “ Connection -> SSH -> Auth” and hit “ Browse …“. Insert your copied key into the text box and hit “ Save“.

For Windows, the software interface is PuTTYgen.exe, whereas, for Linux OS the command-line adaptation is available using SSH commands. While on the other side, Linux OS has the only command-line version that could be accessible using SSH commands.

Enter a username (please mind the info box above the “ User name” field) and select “ SSH public key“. Putty Key How To Generate RSA PuTTYgen.exe is the graphical tool on Windows OS. Login to Azure, select your VM, “ All Settings” and “ Reset password“. In the key field, select the hole content and copy it to the clipboard. Also you want to save the private key (we need it later for PuTTY). It also can generate a SSH-1(RSA), SSH-2 RSA and SSH-2 DSA. The program allows you to generate a public or private key pair, you can load an existing private key file and save the generated key. If your key is created you can optional set a passphrase (this would prompt you for a password on a login with your key). PuTTYgen is an open source RSA and DSA key generation utility. Hit “Generate” and make sure to move the mouse within the blank area of the application. Next you want to make sure that SSH-2 RSA is marked.

Just download the PuTTYgen executable and start it. Get PuTTYgen to generate your SSH keyįirst we need to download another “PuTTY” tool called PuTTY Key Generator. In the following article I want to go over the steps. Generating a SSH key and use the result to log in to your Azure Linux VM is not that hard to accomplish.
