I made tuturials on how use the Porta SFTP Server with public key authentication and use WinSCP. I made a medium write: https://medium.com/@yoxeha5256/organizations-in-various-industries-require-reliable-and-secure-methods-for-transferring-files-c24be6fef321

Thanks for this info as I am wondering why their website does not mention to not support FTP. Though, I really like Porta SFTP Server as it is portable and easy to use, and secure. BUT it is not feasible if you want to upload non-sensitive data that do not have to be in a secure tunnel for faster transfer.

@LRan and for other readers, Porta SFTP Server only supports SFTP/SCP Protocol and it uses the Apache Mina SSHD java based library. It does NOT support FTP/S at all.

That make sense. Sorry as I am new to .NET WinSCP Assembly and SSH/SFTP/FTP. Thank you.

What does this question have to do with WinSCP?
Anyway, indeed, SFTP and FTPS are two completely unrelated protocols. So there's no reason to expect that an SFTP server supports FTPS protocol (and vice versa).

I am creating an automation script for our partners in the Healthcare using SFTP Protocol. I am using Porta SFTP Server (https://portasftpserver.com/portable-sftp-server-community-edition/) for the testing, and I have observed that I cannot test FTP/S Protocol with port 21 with this software. Does anyone encounter the same?
