encrypted harddrive?

Postby bene on Sat Dec 20, 2008 6:24 pm

Hello,

is it possible to set up a encrypted LVM during Linux Mint 6 setup and install the OS on it, like it is with the Ubuntu alternate cd? I plan to install the 64bit version once it's released.
Second thing, will there be any community edition in 64bit?

No, not the way you are thinking about. The current installer won't do it for you. It can be done after the install, but you will have to do it manually, the old fashioned way.

I would suggest you look at TrueCrypt. It is open source and peer reviewed. I think it is one of the best encryption routines out there for Linux.

Hello,

thanks for the quick reply, Fred.

No, TrueCrypt is not what I meant. Or is it possible to encrypt everything with it, including swap? I thought TrueCrypt were good for little encryption tasks which you initiate manually, not for "on-the-fly" encryption of everything as with the mentioned Ubuntu method. With it, everything except /boot will be encrypted. Which is very useful.

To solve this problem, one could set up Ubuntu Intrepid (maybe even 64bit?) and try to install Linux Mint over it. Would this be possible? Or are there deeper modifications than the packages from the Linux Mint repository, which can't be imported that easily?


And still the second question: any Linux Mint 6 CE in 64bit?

bene,

What you said about TrueCrypt used to be true. It has come a long way in the last year or so. You can do on-the-fly encryption/decryption of entire partitions, including swap now. You can even hide an operating system in an encrypted volume so all that can be seen is a honey pot system. You wouldn't even be able to tell encryption was being used.

There may be a 64 bit version coming but it isn't here yet. As far as making Mint out of Ubuntu, it isn't quite that simple. There is a lot more to Mint than just the repos and default codec installations. If you know what you are doing you could try it but I fear you would wind up with the worst of both worlds as opposed to the best of each. What you would be trying to do is to duplicate the efforts of the Mint development team.

Okay, that's news to me. Thanks for the hint, I'll use TrueCrypt then. Sounds like it is more secure then the Ubuntu thing :-)

AFAIK, TrueCrypt is not the software for full-system encryption. dm-crypt (which the ubuntu alt cd uses) is better suited for that. I've been unable to find any documentation to do this with TrueCrypt and Linux (only Windows - http://www.truecrypt.org/docs/?s=sys-en ... pported-os ).

sockrebel,

I stand corrected. I thought it could handle an encrypted Linux partition now too. When I use it on notebooks I usually don't try to encrypt anything but data partitions anyway. I really don't care if the operating system can be seen. OSs are a dime a dozen. It is the data that is valuable and needs protecting.

Anyway, thanks for the correction. :-)
