A ‘secure’ quicktime….. Password protection

[Ryan Mast]

You can encrypt files in a disk image with Disk Utility, but I think that’ll only work with MacOS. Here’s an Apple walkthrough:

That is essentially the same thing as a password zip file. Once the dmg is mounted the file can be copped off. For what he is trying to do it will need to be imbedded into the quicktime file itself.

I personally am not aware of any application that can do this, even if you could find one I would suspect that the application would have to be installed on any computer that the video is played on.

Personally I would look into a password protected website. However even then people can still find a way to download it.

There is NOTHING that is going to completely protect a file.

There are no “technical solutions” to your “artistic problems”.
Don’t let technology get in the way of your creativity!

Thank you both for your thoughts on the matter……………

I’ve trawled the net looking for a solution (cross platform) – and drawn a blank also….. Something whereby everybody who opened the QT would have to type a p/word…..

Thanks again anyhow.

Back in the olden days, “Cleaner” used to do it…you could set all kinds of Quicktime-level options upon encoding. I’m not sure if the “Discreet/Autodesk” incarnation still is capable.

bob is right.
a protection scheme is built inside quicktime:
its called ‘media key’
and there is still a tab to enter them in the qt control panel.

I used it many years ago:
– during encoding with CLEANER there was a way to specify the mediakey,
a simple wordA:wordB pair
– user has to enter/store this mediakey in the QT control panel,
otherwise the protected movie doesnt show its content (white display only).

How secure is the media key? Is that just a metadata setting, or does that actually encrypt the media? Can that be bypassed by stripping the video/audio stream out of the container with something that uses its own QuickTime decoder, like VLC or ffmpeg?
