Hi everybody,
I'm trying to write an app that send a zip file to a SFTP server with
public IP address.
I've installed INDY platform but I can't understand how to use it.
Anyone know how to do it or have a link to a guide?
Thank you.

According to this https://stackoverflow.com/questions/4235714/ftp-
over-ssh-sftp-in-delphi-2010 you can't, since SFTP (which is not the
same as FTP over SSL/TLS) is not supported in Indy.

By SFTP, are you referring to:

- actual SFTP (file transfer subset of SSH)
- FTP over SSH
- FTP over SSL/TLS

?

Many people get them mixed up, but they are completely different and
unrelated protocols.  Of the three, Indy supports only FTP over
SSL/TLS at this time.  It does not support SSH at all.

To use FTP over SSL/TLS in Indy, you can assign a
TIdSSLIOHandlerSocketBase-derived component to the TIdFTP.IOHandler
property, and then you can set the TIdFTP.UseTLS property to
utUseImplicitTLS or utUseExplicitTLS as needed, and set the
TIdFTP.DataPortProtection property to ftpdpsPrivate.

You could try to do it with Synapse in combination with libssh2.

I had some working code somewhere.
