Install PuTTY and PuTTYgen

PuTTY and PuTTYgen are required to convert OpenSSH keys and to connect to the server over SSH. These two tools can be downloaded as executables or, as Windows installer from the PuTTY Download Page. Once installed follow the steps below.

We now need to convert your “Private Key SSH” text file saved earlier, to work with Putty.

 

1. Open the text file and click Save As.
2. Click the dropdown box on “Save as type:” and select “All Files”
3. In the “File name:” field, click on the end of the name, “Private Key SSH” and add .ppk
4. Click “Save”.
5. You will now see two files in your folder.

 

Launch PuTTYgen from the Windows Programs list or Desktop shortcut.

1. Click "Conversions" from the PuTTY Key Generator menu and select "Import key".
   
   
    
2. Navigate to the Private Key SSH.ppk file and click "Open".

3. Under "Actions" / "Save the generated key", select "Save private key".
   
   
4. Choose an optional passphrase to protect the private key.

5. Save the private key to your selected folder and give it a new and appropriate name. For example "Converted_Key".

6. Close PuTTYgen once saved.

Connect to Server with Private Key

Now it is time to test your new converted SSH Private key.

1. Enter the remote server Host Name or IP address under "Session".
   
   
    
2. Navigate to "Connection" > "SSH" > "Auth" > "Credentials".
   
   
3. Click "Browse..." next to "Private key file for authentication".
   
   
    
4. Locate the "Converted.ppk" private key and click "Open".
   
   
5. Finally, click "Open" again to log into the remote server with key pair authentication.
   
   
    
6. Finally, click "Open" again to log into the remote VPS with key pair authentication and a new window will now open.
   
   
    
7. Type in root and hit enter on the keyboard, the key will now authenticate on the VPS.
