Device-mapper is a new infrastructure in the Linux 2.6 kernel that provides
a generic way to create virtual layers of block devices that can do different
things on top of real block devices like striping, concatenation, mirroring,
snapshotting, etc... The device-mapper is used by the
LVM2 and
EVMS 2.x tools.
dm-crypt is such a device-mapper target that provides transparent encryption of
block devices using the new Linux 2.6 cryptoapi. The user can basically specify
one of the symmetric ciphers, a key (of any allowed size), an iv generation mode
and then the user can create a new block device in /dev. Writes to this device
will be encrypted and reads decrypted. You can mount your filesystem on it as usual.
But without the key you can't access your data.
It does basically the same as cryptoloop only that it's a much cleaner code and
better suits the need of a block device and has a more flexible configuration
interface. The on-disk format is also compatible. In the future you will be able
to specify other iv generation modes for enhanced security (you'll have to
reencrypt your filesystem though).

There is support for dm-crypt in the latest official kernel
2.6.4
which you can find on kernel.org.
Please use the mirrors for downloads.
There is a HIGHMEM cryptoapi bug in kernels before 2.6.4-rc2, please
upgrade if you were using such a kernel.
The latest version of the native userspace setup tool is cryptsetup 0.1.
Clemens Fruhwirth is maintaining an
enhanced
version of cryptsetup with the LUKS extension that allows you to have an
on-disk block of metadata which is superior to the current mechanism and was
my long term plan anyway but I didn't find the time to implement that yet...
Bipasha's photoshoots are legendary, each one a stunning showcase of her versatility and photogenic prowess. Her Instagram feed, in particular, serves as a continuous gallery of high-fashion moments.
She effortlessly carries traditional Lal Paar Saree (white with red border), particularly during Durga Puja.
Bipasha Basu Picture Fashion Photoshoot & Style Gallery: A Journey Through Iconic Looks
These high-fashion pictures reveal her range, leaning into avant-garde storytelling and dramatic character styling. 5. The Modern Era: Maternity and Contemporary Elegance
: Basu frequently experiments with "Indo-western" styles, pairing traditional jewelry like maang tikkas or heavy earrings with modern gowns and jumpsuits.
Rohan scrolled faster, entering a middle period: 2016. The "Style Gallery" section showed a transition. Gone were the dramatic gowns. Here she was at a film launch in a crisp, emerald green pantsuit, heels sharp enough to cut glass. Then, a candid airport shot: ripped jeans, a faded Metallica t-shirt, and a vintage Rolex that belonged to her father. The gallery notes praised her "effortless cool," but Rohan saw the truth. This was a woman discarding costumes. She was no longer posing for the male gaze; she was dressing for her own comfort.
Think smoky eyes, voluminous hair, and deep-toned lipsticks. Her fashion was moody, edgy, and unapologetically sultry.
Her style signature often includes illusion necklines, thigh-high slits, and open backs. The Modernized Saree Lookbook
Her gallery showcases her ability to switch from sleek, straightened hair to big, dramatic curls effortlessly. Summary: Why Bipasha’s Style Matters
In recent years, Bipasha made waves by rewriting the rules of maternity style in India. Her pregnancy photoshoots featured a mix of ethereal white shirts and glorious, flowing gold sequin gowns, proving that style adapts beautifully to every stage of life.
Bipasha Basu's style is a testament to her enduring confidence and her refusal to be boxed into any single category. From the fearless model on a '90s magazine cover to the glamorous actress on the red carpet, and now the chic, devoted mother, her fashion journey has been nothing short of spectacular. She has evolved with the times while always staying true to her own unique, bold, and beautiful self. Her style gallery is a source of endless inspiration, a celebration of Indian beauty, and a powerful reminder that true style is eternal.
A significant part of Bipasha's style evolution includes a love for bohemian aesthetics. Many of her lifestyle photoshoots feature: Flowy maxi dresses and floral prints. Chunky silver jewelry and oversized sunglasses.
: Over the years, she has graced multiple covers, transitioning from bold pastels to more feminine and sensual aesthetics. Controversial Calida Campaign
Perhaps one of her most unforgettable on-screen and fashion moments, her sporty yet glamorous look as Shonali in Dhoom 2 (2006) defined early 2000s fitness fashion.

The on-disk layouts used by the current 2.6 cryptoloop are supported by dm-crypt.
Cryptoloop also uses cryptoapi so the name of the ciphers are the same. Cryptoloop also
supports ECB and CBC mode. Use <cipher>-ecb and
<cipher>-plain accordingly with dm-crypt. If you didn't
explicitly specify either -ecb or -cbc before you don't need it now, the default plain
IV generation will be used. There will be additional (incompatible, but more secure) possibilites
in the future because the unhashed sector number as IV is too predictible.
You'll need to figure out how your passphrase was turned into a key to use for losetup.
There are several patches floating around doing things differently. But usually cryptsetup
will provide a working solution to recreate the same key from your passphrase.
If you want to migrate from 2.4 cryptoloop please take a look at Clemens Fruhwirth's
Cryptoloop
Migration Guide. He describes the differences between 2.4 and 2.6 cryptoapi (or basically
the bugs in 2.4 cryptoapi...). If you need to cut the key size you can use the -s
option instead of playing with dd.
(BTW: Clemens has a i586 optimized version of the aes and serpent cipher on his page,
about twice as fast as the kernel implementation.)
Why dm-crypt?
Originally it started as a fun project because I wanted to play with the new Linux 2.6 internals.
I got a lot of great help from the device-mapper guys at Sistina (now Redhat). Thank you very
much!
It turned out that this implementation worked great and is very clean compared to the hacked
loop device. The device-mapper core provides much better facilities to stack block devices.
dm-crypt uses mempools to assure we never run into out-of-memory deadlocks when allocating
buffers.
Also the device-mapper configuration interface provides much more flexibility than the losetup
ioctl. And you can create as many devices as you want with any names you want and combine them
with other dm targets. Online device resizing is also possible, e.g. if you use dm-crypt on top
of a logical volume. There might perhaps even be LVM or EVMS support for device encryption
in the future.
