To encrypt (and zip) this folder, right-click it. For this example, it’s a folder containing a video interview of Linux security expert Jay Beale, along with the art and music used in its production. Let’s pick a file or folder to encrypt before we upload it to Google Docs (or to any cloud service you prefer). And, whichever desktop OS you use, this tool helps you to protect your cloud data. The procedure is just as simple in other OSs. To exploit all this encryption power in Windows, all you need to know is how to right-click and to set a few simple items. Maybe the NSA or the Russian government can crack it, but the putative hacker sitting on his bed in his mother’s basement almost certainly cannot.īest of all, 7Zip is easy to use. 7Zip also does AES-256 bit encryption, which is military grade. In the end it turned out that the easiest and best one is a program I already had: 7Zip.ħZip is an excellent zip and unzip program that’s available for Windows, Mac, and Linux. I looked at several cloud data encryption applications, including Encrypto, which is good, free, and versatile if you use Mac or Windows nCrypted Cloud, which seems to be pretty corporate-oriented (and again, just Mac and Windows) Sookasa, which has no free version for personal use and a whole raft of others. So it’s probably a good idea to encrypt any information we store in the cloud, especially since it’s easy to do - and free, as well. But even if it has, another one always seems to come along. Of course, that particular security hole has been closed by now - we hope. As the ZDNet story about the problem pointed out, “The so-called ‘man-in-the-cloud’ attack is said to be a common flaw in most cloud-based file synchronization services.” In the summer of 2015, an exploit was discovered that let baddies get into Google Drive, Dropbox, and OneDrive accounts without knowing your password. We all trust cloud-based file storage services to keep our data safe from prying eyes, right? Maybe we shouldn’t.
