Standard SSL uses 2048byte key size. It's a standard key size considered to be secure enough for commercial and financial transactions.
However it takes no effort for them to use 16kb key size and implement 100 million key transformation cycles.
No amount of GPUs in the world will be able to bruteforce that kind of encryption. Not even NSA.

JiggaJonsonsaid:

Has anyone tackled the encryption through GPU means? As in this: http://boingboing.net/2012/12/05/cracking-passwords-with-25-gpu.html

depending on how much data you have, this actually should be relatively easy to spot/stop.

It takes a while to encrypt a lot of data. With so many people using torrenting more and more to download large video files. Its going to take a long time for it to encrypt all of that. Now yeah, if you just have a bunch of spreadsheets and word documents in your my docs folder, yeah you're probably fucked. But IMO, you shouldn't keep small docs like that on your computer, you keep them on a flash drive not always connected to your computer. Just following with the idea that nothing critically important should be connected 24/7 to the internet anyway.

If you see your hard drive active non-stop even when you're not doing anything, that's your first clue something is amiss.

If I was a hacker I would feel fairly confident that at least 95% of PC users would have no idea what you are talking about.
