wodSFTP is a client component that provides implementation of SFTP (secure file transfer on SSH) protocol. Use it to transfer your file securely over encrypted network layer (using SSH2 protocol). SFTP is not just some "FTP over SSH" wrapper - it is newer protocol, supported by all SSH2 servers. Don't give up to your privacy any more! Don't send plaintext passwords using regular old fashion FTP protocol. Don't expose contents of your files! Try SFTP! It's a standard already.
