loop aes
Curious if any has done this and any reads on how this works? Also what is the benefits of this kind of security. It seems that this kind of security would keep the avg person from gaining access to your hard drive but how hard is the crypto?

Do you mean how hard to implement, or how hard to break the crypto?

as far as implemenation, It took me a good sunday/saturday afternoon.

there's a good tutorial somewhere that made it fairly clear to me. but it really depends what you want to use it for. as far as I know (if you use multi-key mode) the only remotely efficient way of cracking it is someone getting a subpoena that forces you to give up your keys.

Well as far as implementing it goes. I saw something with dm-crypt seems a little easier to implement. I don't know if you have used that before? If you could link that article that showed you how to do it that would be great. I guess if it came to a subpoena you could always plead the 5th. But then again w/ Homeland Security i don't even think pleading the 5th matters anymore.

there's steganography for them, essentially any process of hiding data or making it impossible to prove the existence of.. combined with strong crypto, you beat the system.

I found this to be very helpful, I didn't actually get much out of the tutorial bits as I had none of the goals presented in the document, but it gave me the knowledge to unleash the creativity within me not that I have a practical use for any of it.

whatever you get out of the document, the techniques and tools for doing block device encryption are really fascinating and quite elegant.

Very good Reads. I ended up using cryptsetup. I was able to encrypt my swap and my second hard drive. I just get an error that I cannot mount the partition at bootup. Thanks for the replys
