I have a remote server on a computer with Windows 8, using the program WinSCP to access. I want to access the server from another computer. The situation is I have not the password, so I want to know, if I can clone the private key to the another computer and how to do that. Somebody can help me?
Private key is just a file. So copy it over to the other machine.
As you are using WinSCP and are able to login with it, you probably have a key file path configured in your stored session.
