cryptsetup (with Linux Unified Key
Setup - LUKS) here: https://gitlab.com/cryptsetup/cryptsetup.
Old page:
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...
Are you looking to play this on a or on the PPSSPP emulator ?
If you want English voices on the PSP, you are out of luck. The PSP UMD does not have the storage capacity for the dual-audio track. The patch is text-only.
Whether you are a legacy player wanting to revisit the "Susano'o Unit" arc or a new fan who just finished BlazBlue: Calamity Trigger on an emulator, this patched ISO is your next stop.
In the "Output" field, select where you want to save the new file. Name it something clear, like BlazBlue_CSE_English.iso .
From the CSII (English) ISO, extract the folders labeled localize (text) and voice (audio).
An RPG-lite survival mode that is perfect for short handheld sessions.
The is complete enough for full enjoyment of story mode and arcade. If you only own a PSP (or want high-res portable play via PPSSPP), it’s the best way to experience Continuum Shift Extend in English.
Safely disconnect, navigate to on your PSP, and boot the game. For PPSSPP Emulator: Open the PPSSPP application.
In the Extend (Japanese) ISO, replace the corresponding folders in the same directory with the ones you just extracted.
Because Arc System Works skipped a localized PSP release for Extend —focusing instead on the PlayStation Vita and home consoles in the West—the Japanese PSP ISO was left untranslated. The game was technically playable due to English menus in the Japanese release, but the massive, narrative-heavy Story Mode was completely unreadable to non-Japanese speakers.
While BlazBlue: Continuum Shift Extend was released in Japan, the game's popularity soon spread globally, and fans began to demand an English translation. Unfortunately, an official English release was never announced, leaving fans to rely on fan-made translations and patches.
Features the brutal "Unlimited Mars Mode" and an enhanced "Abyss Mode" for RPG-like character progression.

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.
