Show SFTP fingerprint at first connection

SFTP Clients like WinSCP or FileZilla shows the ssh fingerprint at first connection. On my first connection on RaiDrive it didnt show the fingerprint. I wonder if there is a way to show the fingerprint. If the fingerprint is not shown, it concerns me a lot about safety.

Hi~ @Kison_He ,

Thanks for the good suggestion.
We will include it in our development plan.
We will release it as soon as possible.
