SSH/SFTP client in D3D app?

Hello. Is there any way to achieve giving the user the ability to add login credentials to access a server within a D3D Unity app for the HoloLens? Ideally I'd like the user to be able to log in and transfer files to the HoloLens for data visualization. I contacted the developers of the SSH Pro asset and they said their asset probably wouldn't work as it requires UWP support.
