I just started using CGD for netbsd, it's a pretty nifty little app that's included with the OS, it encrypts the entire disc. http://www.netbsd.org/guide/en/chap-cgd.html
Right now I'm just running it on a small 40 gig test drive.
if you have your entire drive encrypted in such a way that it looks liek random data, couldn't you just deny everything? "Encrypted drive? I have no idea what your talking about" "What's on my 400 Gig drive? I don't have anything on it"
Or even a lot of us set up computers for our friends and such, so coudln't you use the opposite of that as well "this guy i met online set up my system for security, I don't know what he did, here's his handle *insert bogus handle*"
"Password? I don't remember" It's not uncommon for someone to forget a password.
Based on my onderstanding of the US laws:
While they can say "he has 500 GIgs of possibly encrypted files", if they can't prove what the files are that's really just something they can take into consideration but can't jail you for based entirely on that fact.
I want to start using Disc Encryptioin myself, but i'm paranoid up the ying yang as I"ve been watching nothing but the X-files for the past week. Got the DVD collection, and having my own personal marathon. Just because your paranoid doesn't mean they're not out to get you.
When one of my buddies and I use to transfer files between our computers we were create an encrypted tunnel between our machines, so that all data the travels this "tunnel" would be encrypted and thus not allowing our ISPs (and anyone else watching) to know what it is.
