Give users ability to specify their own device/ssh key

[ChadBailey]

I wanted to check out this tool, but I appear to be forced down the path of it auto-generating an SSH key for me. I did most of the process, but my car is out in the driveway so I'm too lazy to go physically toggle the ssh settings to consume the new key. This experience makes me want to suggest the following (and maybe this should be split up)

• If user has existing ssh key at ~/.ssh/id_rsa attempt using it first (as the built-in ssh client does on windows, mac, and linux)
• Allow the user to specify their own ip address rather than forcing a scan
• Allow the user to specify their own ssh private key location

I realize this tool is intended for newbs, but sometimes us non-newbs enjoy using a nicely made tool so having these options will make it more user friendly for people who are already familiar with ssh keys.

Hi, I have an existing .ppk file generated by PuTTY. I would also like to do this. How can we import an existing ssh private key file?
