Connecting Oracle Cloud VPS via SSH with Private Key using PuTTY
If we choose to connect to the instance with PuTTY, there lies a problem. Oracle Cloud configure system provides the Private Key with the format .key, However, the Putty needs .ppk file. They are not compatible. If we are planning to use a private key file generated during the instance creation process we need to convert the file to a .ppk file before we can use it with PuTTY to connect to the instance.
