I have a Windows Forms Application which communicates with an FTP Server everything works

  • 0

I have a Windows Forms Application which communicates with an FTP Server everything works flawlessly, except that the user is able to use WireShark, filter for FTP and easily get full access to my FTP Server. I really need a way to prevent this, but the only idea I could come up with was to use SFTP or FTPS. The problem is that currently I’m using edtFTPnet free and couldn’t find any free SFTP or FTPS class to implement on my current code.

What would be the best approaches (free or extremely low cost) to solve this problem?

    There are a few free SSH libraries: (SharpSSH, SSH.Net for example)

    The problem is you’re relying on someone not looking at the password. Instead, issue your clients their own credentials. Be it, username & passwords per user or issue the client a certificate.

    Also, Daniel’s advice is sound; make sure that if they DO get the password, there’s little to no damage that can be done
