File Encryption

The next version of WinSCP will allow your to seamlessly encrypt your files on an SFTP server using AES-256 encryption.

As part of session settings, you specify (or have WinSCP generate) an encryption key. WinSCP will then (by default) seamlessly encrypt all newly uploaded files and their names.

In WinSCP file panel, you will see original file names and when you download files, you will get original contents. But anyone else, who does not know the key, including a server Administrator, will see only gibberish.

This, combines with WinSCP powerful synchronization features, allows you to use your server quota as a safe backup storage for your private data.

The following images show how an encrypted folder and files show to users who knows and does not know an encryption key:
