NetStream protection Created Mar 12, 2010

nobody about netstream security?

One thing I can tell you ... You can't encrypt anything in MD5.

MD5 is a one way hashing function, it produces a Digest or "fingerprint" of some data that is a predictable length and relatively unique to the data.
Even slight changes to the data should result in a noticeable difference in the fingerprint.

Since MD5 produces a fixed length output, there are a finite number of possible outputs for an infinite number of inputs, thus it is impossible to determine the input from the output.

Otherwise you're basically out of luck.
To be able to view it you have to have a copy of it, and someone determined enough will be able to save that copy.

One thing nice with NetStream and good buffer usage, is that you have no copy outside the flash player buffer so no body can copy the movie from the player.

The bad thing is that i have to target a sure database with true url. It's when my player is asking for the video through the browser (i do think )... some plugins catch it by the browser.

it's a really kick-ass issue

It's still being provided to the browser, so someone determined enough can copy it out.

You've been misinformed. Flash in a browser is an application of the browser, and the browser continues to do all the net requests via NetConnection. NetStream is a channel within NetConnection. Therefore it is always possible to monitor the traffic managed by the browser. You can readily see this in the Activity process displayed by Safari (other latest browsers have something similar).

Thanks for all your help.

So ... it seems like is impossible to secure by an easy way my NetStream :(

I will continue to search a simple solution because, i think, it's an issue for many Flex developpers.

Best regards,
