FTPS Guide

Hi, I recently migrated from Plex to infuse. I tried SMB and it works great with straight forward file sharing feature, but I am concerned about the security, so I’m looking into FTPS over SSL (considered to be the fastest and secure over SSL based on my research).

Can anyone provide me a guide on how to set this up with appropriate SSL certificate? Most tutorials I found online skips the SSL part.

If you think SMB can be made secure, I am open to that as well. Any suggestions are appreciated.
