Here is my question on SFTP, as per i'm a little confuse at the moment.
I'm using the letsencrypt container from linuxserver and registered a domain on duckdns.
Just tried with WinSCP and i can connect to my domain using its name registered on duckdns on a port that i have forwarded to port 22. That's ok.
What i do not understand is, is this secure? Is this connection using the certificate created by the letsencrypt container?
I see in WinSCP that i'm using SSH-2, and AES 256 algo.
