Hi, everyone!
Recently, as I told on another thread, I installed openSUSE in dual
boot with Windows.
I would like to encrypt a partition I use to store my personal files
(Documents, Downloads, Pictures, Music and Videos). I want to use a
file system that can be mounted read/write on both Linux and Windows.
Is there any recommendation/advising/suggestion on which encrypted
file system I could use to achieve that?
I searched the opensuse and opensuse-factory mailing lists and didn't
find any for Leap 42.3 and 15.0.
openSUSE docs talks about LUKS, but I googled briefly and LUKS support
on Windows is abandonware...
Maybe I explain better showing my partition setup:
Windows recover partition - 499MB
Windows reserved partition - 99MB
Windows (C:) - NTFS - 100GB
openSUSE (/) - Btrfs - 100GB
Personal files (D:) - NTFS - 200GB *
Home (/home) - XFS - 30.53GB **
Swap - 16GB
* This partition I want to encrypt and have it accessible on both
Linux and Windows
** This partition I just want to encrypt
Thank you in advance!

Hello:
I don't know if there is any program that works both in windows and
linux
and can encrypt partitions directly.
But there are at least 2 programs which work in both linux and windows:
bestcrypt (https://www.jetico.com/) - proprietary, currently supports
(works on)
opensuse 13.x 42.1 42.2 but not 42.3 and Leap 15.0. It is available
in
binary form, and builds custom kernel modules at installation.
veracrypt (https://www.veracrypt.fr/en/Home.html) - open source, free.
Available in binary form, does not require kernel modules, works on
more systems
than bestcrypt, I guess.
With both you can create large encrypted files which can be formatted
to
different file systems that can be mounted where you want.
I don't know if working with 100-200 GB files is feasible, but a few 10
GBs is
not a problem.

If you used full disk encryption, you could maybe reduce the problem
by just finding file systems that can be used on both OS's.
That could end up being native MS NTFS or
EXTn with a windows driver. There are several of these on
the web, some free, some cost small money
https://shop.paragon-software.com/80/purl-all-secure-shop?cart=174929&x…
But none of those support encryption on the windows side, which is why I suggested
full disk encryption.

There is nothing which comes with the system. veracrypt
(https://www.veracrypt.fr/en/Home.html) would fit the bill if you can
find a filesystem that works on both sides.
It's available on both Windows and Linux (and Mac). The main trouble is
chosing a file system which works well on both sides.
Options:
ext - Excellent Linux support, poor Windows support. Probably not usable
in Windows 10 since drivers need to be signed.
FAT - Good support on Linux, excellent support on Windows. Problem: File
size limit is 4GB. That means no movies for you and FAT has almost no
support for permissions.
NTFS - Supported by Linux but not on the same level as FAT. Excellent
support on Windows.
You can try a commercial NTFS driver, for example the one from Paragon:
https://www.paragon-software.com/ntfs_linux_index.html
I don't have any experience with it.
Conclusion: Should be simple but isn't.
Workaround: Set up a file server and put your personal files there.
Encrypt the files in the file server. Use NFS or SMB to access them.
Advantage: If you set up a VPN, you can access your files worldwide and
securely.

Thank you for all of your answers! From what you answered and what
I've been reading, it seems I have just one way to go (considering
what I want to achieve, especially dual-boot):
2018-07-05 13:25 GMT-03:00 Istvan Gabor <suseuser04(a)gmail.hu>hu>:
veracrypt (https://www.veracrypt.fr/en/Home.html) - open source, free.

Works on both Windows and Linux, is powerful and featureful. I think
I'm going to use it to encrypt my personal files (D:) partition.
Maybe encrypting my home partition is not really necessary. I'm going
to search how I can add extra security to my browser stored passwords,
though.
With both you can create large encrypted files which can be formatted to
different file systems that can be mounted where you want.
VeraCrypt supports encrypting entire partitions too.
I don't know if working with 100-200 GB files is
feasible, but a few 10 GBs
is
not a problem.
Istvan
According to what I've been reading, performance penalty is almost negligible.
And according to VeraCrypt's own documentation
(https://www.veracrypt.fr/en/FAQ.html), "Partitions/drives may be
better as regards performance" (when compared to File containers).

How life is... less than a week ago, he was alive and answered a doubt
of mine. Now, I can't talk to him... RIP John Andersen...
But if I understood him well, by "full disk encryption" he meant what
VeraCrypt calls "partition volume". That is exactly what I'm looking
for.

I'm going to use VeraCrypt + NTFS.
NTFS - Supported by Linux but not on the same level as
FAT. Excellent
support on Windows.
I've been using NTFS on Linux without problems since I started using
Linux (by 2008, good times... Brazilian's Kurumin Linux based on
Debian 4.0 etch).
Maybe because I'm the only user of the computer and I set the NTFS
permission mask in a way that it ends up like 777...
Workaround: Set up a file server and put your personal
files there.
Encrypt the files in the file server. Use NFS or SMB to access them.

Interesting and ingenious solution, but I want something more simple...

No, full disk is full disk, all the partitions. The entire disk. I don't
know of a software solution for full disk encryption for both Windows
and Linux. There is a firmware method, if the firmware supports asking
for the password before booting.

Don't use exFAT if you work with (or might need to work with) files >4GB in

The cited 4GB file limit indicates that the thumb drive actually was
using FAT32 (which is directly supported on Linux), and not exFAT.
exFat supports files up to 16 Exabyte, but is not natively supported on
Linux. It can be used via a fuse driver, available on packman.

No, exFAT file size limit is 128 PiB. You were probably using FAT.
