Sorry to keep beating this to death. I have secure-server installed on Ubuntu server. I have PuTTY on Windows. Everything is working. I am just confused about the key pairs. I generated the key pair with "keygen". the key pairs are in my .ssh directory on my server home directory. what is NOT clear is where do I put the public key on Windows? A Google search said put the public key in the "home" directory. Does Windows have a "home" directory that I am not aware of? There is a windows user "ray" under the "Users" folder. I put the key in the folder where I am launching PuTTY.exe from. How do I prove the keys are working?
