Strongspace is a safe place to gather, store, back up, and share any type of file. You can upload and download files via SFTP (Secure File Transfer Protocol), HTTPS (Web browser access over Secure Socket Layers) and even RSYNC over SSH (a rapid, low bandwidth way to "sync"). Strongspace is designed so that everything happens over a secure, encrypted connection. Your password and other sensitive information is encrypted with Blowfish, and files are moved to-and-from servers to your computer over encrypted channels at all times.
