In this example, the input file to be included in the archive is “secret-video.mp4” (as shown earlier) and the resultant output encrypted ZIP archive file is “secret-video.zip” in the same folder. To create an encrypted archive file version of this video file, in the cross-platform friendly ZIP Archive format, open up the Terminal app (you can find it in Applications > Utilities) and type in exactly: Now, to start, here’s a video file ready to share with a client: Don’t panic, I’ll show you exactly what to type in and it’s definitely something you can handle.īonus: If you’re worried about DMCA filters on Dropbox, encrypting the file with your own password should sidestep the issue, though I still discourage you from sharing files that you don’t have the legal right to share, of course. Which leads to the question: how do you create an encrypted, secure ZIP archive file on a Mac system? Turns out that it’s straightforward, but you have to be willing to get your hands just a bit dirty with a command line sequence. All of those can add up to a service that offers good security and much convenience, but possibly not sufficient security for truly private or secret content or enterprise work.

Security experts aren’t impressed, and I know that if you upload a file with a “hash” analysis that matches a file that was removed for copyright violations it can be rejected by the Dropbox server. Your client is right to be skeptical of the encryption used on Dropbox.
