Encrypt home folder

Postby easy1 on Sun Feb 11, 2007 10:32 am

I've not installed or even downloaded Linux Mint yet. I'm hoping to find out if there are any options to encrypt home folders. I'm currently a Windows user and I use TrueCrypt (http://www.truecrypt.org) to create file-hosted volumes, which I can backup, copy, move etc like a normal file.

I'm hoping that if the PC is stolen, and someone then has physical access to the pc they won't be able to access the folder. Once someone has access to the PC, they can do whatever is required to reset the root password and I hope that wouldn't allow them to simply remove the encryption without the passphrase.

My hope is that the recommended process creates a file on the hard disk that contains the encrypted home folder, so that it could be copied to another installation and used easily.

Many thanks for your help. I have searched on Google and there seem to be a few methods mentioned. However, I'm hoping that someone could advise the easiest way to achieve this.

And why wouldn't the thief just repartition and reformat your harddrive?

EDIT:

Forgot to add the link I wanted to add :roll: ... OK, here we go: Maybe some of the utilities mentioned in this article here offer what you are looking for?

That would be more than fine with me! I want something to make it much more difficult for the thief to access the data. I wouldn't care what they did with the hard drive - I'm just hoping to find a solution that makes it more likely that they won't bother trying to access my data and instead wipe it.

I'd put a PIN code or a password into the BIOS so that the machine's system setup cannot be accessed without having to type it in every time; same of course for the system boot: protect it with a password. Then replace the ordinary screws with high-security screws as far as this is possible. I don't know where you are based, but here is e.g. a NY based company that sells such screws: http://www.tamperproof.com/

Search for "security screw" or "tamperproof screws" in Google, it will give you many hits. Not all of these companies will sell these screws to individuals, but e.g. I got mine by having them shipped to my workplace (they thought I was ordering this stuff on behalf of my employer ... ) so I guess you can apply similar tricks. Or if you know any nice folks at any computer store they can probably order this stuff for you, e.g. by claiming they have to make a laptop tamper-proof because their customer is a member of a foreign embassy .... be creative. :wink: If your BS is credible enough you will have such screws in no time. 8)

Having such screws on your laptop renders it useless for the thief. Absolutely useless. He cannot remove the disks, he cannot boot the machine, he cannot remove any parts. For a thief it's a dead brick.

Make sure you put on a sticker on the laptop saying something like that the laptop is tamper-proof and not worth stealing, put your phone number and your address and that anyone returning the laptop to you will be properly rewarded ... (e.g. 100$ ?)

A somewhat paranoid coworker of mine had his laptop stolen, and the thief, being totally frustrated about having stolen a useless brick, was dumb enough to bring it in "for repairs" (= to have the screws removed!) .... to the very PC shop where we got our screws from :lol:

As for encryption ... I'm currently on OpenSUSE 10.2 due to some job related stuff I have to get done and here it's easy to have your partitions encrypted ... I don't know how to do this on Ubuntu and Mint ... so you'd have to google around in the Ubuntu forums, maybe there is a how to or something ....

With those screws also come special screw drivers. If anyone could buy the screws or the screw drivers freely and without limitations, the purpose of those special screws is defeated. :wink: In that case you can just leave the normal screws on your system.

So that's why certain producers of such special screws put limitations to whom they sell this stuff. But as I said, there are ways to get around this limitation. 8)

Yes I have incorrectly understood! I thought that for Linux is not present drivers for these hard disks, thanks
