I wonder if your having an issue in character coding between Windows 
and Linux.  Try setting a second key that is basic for testing and see 
if it works.  You can delete it later.


luksAddKey
luksRemoveKey or luksKillSlot

Hope I pointed you in the right direction.  Let us know how it goes.

mounting encrypted linux partition on windows

2009-05-20 Thread Damián Rodrí­guez Sánchez


I recently decided to encrypt the / Linux partition (ext3) on my
dual boot PC (Windows Vista - Fedora 10).

I used to mount it with Ext2 Installable File System for Windows
(http://www.fs-driver.org) when using Windows, but now that the
partition is encrypted, its contents (obviously) appear unreadable
and I'm offered to format it.

I was told that software like FreeOTFE and TrueCrypt should let me

How was it encrypted? If you used luks, it's likely that Truecyrpt won't
work with that.

I don't think linux has a way to boot off a Truecrypt encrypted root.

I you want to share a partition between Windows and Linux, I think it will
need to encrypted with some application that is available for both, and will
not be usable on / (perhaps /home will work for you). If you want it mounted
during the boot process you'll probably need to do some customization (make
an initscript or and some stuff to rc.local).

Depending on what you are really trying to do, virtualization may be another
path to getting what you want.

Yes, I think I used LUKS, that's the default during Fedora installation, 
isn't it?


So I probably won't be able to use TrueCrypt, but FreeOTFE should work:
FreeOTFE supports LUKS to v1.1 of the LUKS specification. This is the 
latest version at time of writing (2nd December 2007), according to them.


I guess I'll reinstall Fedora without enabling encryption during the 
installation process and then log in and try this:


http://www.freeotfe.org/docs/Main/Linux_examples__dm-crypt.htm#level_3_heading_3


I don't think linux has a way to boot off a Truecrypt encrypted root.


Yes, I must leave the /boot partition without encryption, is that what 
you mean? Anyway, I intend to try again with FreeOTFE first.

I also use virtualization, but unfortunately I sometimes I have to use 
Windows directly.


Thanks.

I don't think you'll be able to use it for root either, unless you do some
customization to the initrd. Getting it to work for /home will probably
be significantly easier.

Yeah, but that's with luks. I was talking about if you switched to Truecrypt
so that you could see the partitions under Windows.

However, using the other tool that supposedly handles luks should work.
