* The default size of the LUKS2 header is increased to 16 MB.
It includes metadata and the area used for binary keyslots;
it means that LUKS header backup is now 16MB in size.
* Cryptsetup now doubles LUKS default key size if XTS mode is used
(XTS mode uses two internal keys). This does not apply if key size
is explicitly specified on the command line and it does not apply
for the plain mode.
This fixes a confusion with AES and 256bit key in XTS mode where
code used AES128 and not AES256 as often expected.
* Default cryptographic backend used for LUKS header processing is now
OpenSSL. For years, OpenSSL provided better performance for PBKDF.
* The Python bindings are no longer supported and the code was removed
from cryptsetup distribution. Please use the libblockdev project
that already covers most of the libcryptsetup functionality
including LUKS2.
* Cryptsetup now allows using --offset option also for luksFormat.
* Cryptsetup now supports new refresh action (that is the alias for
"open --refresh").
* Integritysetup now supports mode with detached data device through
new --data-device option.
- 2.1.0 would use LUKS2 as default, we stay with LUKS1 for now until
someone has time to evaluate the fallout from switching to LUKS2.

- remove old upgrade hack for upgrades from 12.1
- New version 2.0.5
Changes since version 2.0.4
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Wipe full header areas (including unused) during LUKS format.
Since this version, the whole area up to the data offset is zeroed,
and subsequently, all keyslots areas are wiped with random data.
This ensures that no remaining old data remains in the LUKS header
areas, but it could slow down format operation on some devices.
Previously only first 4k (or 32k for LUKS2) and the used keyslot
was overwritten in the format operation.
* Several fixes to error messages that were unintentionally replaced
in previous versions with a silent exit code.
More descriptive error messages were added, including error
messages if
- a device is unusable (not a block device, no access, etc.),
- a LUKS device is not detected,
- LUKS header load code detects unsupported version,
- a keyslot decryption fails (also happens in the cipher check),
- converting an inactive keyslot.
* Device activation fails if data area overlaps with LUKS header.
* Code now uses explicit_bzero to wipe memory if available
(instead of own implementation).
* Additional VeraCrypt modes are now supported, including Camellia
and Kuznyechik symmetric ciphers (and cipher chains) and Streebog
hash function. These were introduced in a recent VeraCrypt upstream.
Note that Kuznyechik requires out-of-tree kernel module and
Streebog hash function is available only with the gcrypt cryptographic
backend for now.

Changes since version 2.0.3
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Use the libblkid (blockid) library to detect foreign signatures
on a device before LUKS format and LUKS2 auto-recovery.
This change fixes an unexpected recovery using the secondary
LUKS2 header after a device was already overwritten with
another format (filesystem or LVM physical volume).
LUKS2 will not recreate a primary header if it detects a valid
foreign signature. In this situation, a user must always
use cryptsetup repair command for the recovery.
Note that libcryptsetup and utilities are now linked to libblkid
as a new dependence.
To compile code without blockid support (strongly discouraged),
use --disable-blkid configure switch.
* Add prompt for format and repair actions in cryptsetup and
integritysetup if foreign signatures are detected on the device
through the blockid library.
After the confirmation, all known signatures are then wiped as
part of the format or repair procedure.
* Print consistent verbose message about keyslot and token numbers.
For keyslot actions: Key slot <number> unlocked/created/removed.
For token actions: Token <number> created/removed.
* Print error, if a non-existent token is tried to be removed.
* Add support for LUKS2 token definition export and import.
The token command now can export/import customized token JSON file
directly from command line. See the man page for more details.
* Add support for new dm-integrity superblock version 2.
* Add an error message when nothing was read from a key file.
* Update cryptsetup man pages, including --type option usage.
OBS-URL: https://build.opensuse.org/package/show/security/cryptsetup?expand=0&rev=141
- Update to version 2.0.0:
* Add support for new on-disk LUKS2 format
* Enable to use system libargon2 instead of bundled version
* Install tmpfiles.d configuration for LUKS2 locking directory
* New command integritysetup: support for the new dm-integrity kernel target
* Support for larger sector sizes for crypt devices

- version 1.6.4
- new tarball / signature location
* Implement new erase (with alias luksErase) command.
* Add internal "whirlpool_gcryptbug hash" for accessing flawed
Whirlpool hash in gcrypt (requires gcrypt 1.6.1 or above).
* Allow to use --disable-gcrypt-pbkdf2 during configuration
to force use internal PBKDF2 code.
* Require gcrypt 1.6.1 for imported implementation of PBKDF2
(PBKDF2 in gcrypt 1.6.0 is too slow).
* Add --keep-key to cryptsetup-reencrypt.
* By default verify new passphrase in luksChangeKey and luksAddKey
commands (if input is from terminal).
* Fix memory leak in Nettle crypto backend.
* Support --tries option even for TCRYPT devices in cryptsetup.
* Support --allow-discards option even for TCRYPT devices.
(Note that this could destroy hidden volume and it is not suggested
by original TrueCrypt security model.)
* Link against -lrt for clock_gettime to fix undefined reference
to clock_gettime error (introduced in 1.6.2).
* Fix misleading error message when some algorithms are not available.
* Count system time in PBKDF2 benchmark if kernel returns no self
usage info.

* Fix loop-AES keyfile parsing.
* Fix passphrase pool overflow for too long TCRYPT passphrase.
* Fix deactivation of device when failed underlying node disappeared.
- There is a bug in the released tarball, due to HAVE_BYTESWAP_H
and HAVE_ENDIAN_H not properly handled by the buildsystem. A
patch with permanent solution was sent and accepted upstream
and will appear in the next release, for now an spec file workaround
is in place, remove in the next update.

Verify GPG signature: Perform build-time offline GPG verification.
Please verify that included keyring matches your needs.
For manipulation with the offline keyring, please use gpg-offline tool from openSUSE:Factory, devel-tools-building or Base:System.
See the man page and/or /usr/share/doc/packages/gpg-offline/PACKAGING.HOWTO.
If you need to build your package for older products and don't want to mess spec file with ifs, please follow PACKAGING.HOWTO:
you can link or aggregate gpg-offline from
devel:tools:building or use following trick with "osc meta prjconf":
--- Cut here ----
%if 0%{?suse_version} <= 1220
Substitute: gpg-offline
%endif

* Add --device-size option for reencryption tool.
* Switch to use unit suffix for --reduce-device-size option.
* Remove open device debugging feature (no longer needed).
* Introduce cryptsetup-reencrypt - experimental offline LUKS reencryption tool.
* Fix luks-header-from-active script (do not use LUKS header on-disk, add UUID).
* Add --test-passphrase option for luksOpen (check passphrase only).
* Introduce veritysetup for dm-verity target management.
* Both data and header device can now be a file.
* Loop is automatically allocated in crypt_set_data_device().
* Require only up to last keyslot area for header device (ignore data offset).
* Fix header backup and restore to work on files with large data offset.
* Fix readonly activation if underlying device is readonly (1.4.0).
* Fix keyslot removal (wipe keyslot) for device with 4k hw block (1.4.0).
* Allow empty cipher (cipher_null) for testing.
* Fix loop mapping on readonly file.
* Relax --shared test, allow mapping even for overlapping segments.
* Support shared flag for LUKS devices (dangerous).
* Switch on retry on device remove for libdevmapper.
* Allow "private" activation (skip some udev global rules) flag.
OBS-URL: https://build.opensuse.org/package/show/security/cryptsetup?expand=0&rev=91
* Fix header check to support old (cryptsetup 1.0.0) header alignment. (1.4.0)
* Add --keyfile-offset and --new-keyfile-offset parameters to API and CLI.
* Add repair command and crypt_repair() for known LUKS metadata problems repair.
* Allow to specify --align-payload only for luksFormat.
* Unify password verification option.
* Support password verification with quiet flag if possible. (1.2.0)
* Fix retry if entered passphrases (with verify option) do not match.
* Support UUID=<LUKS_UUID> format for device specification.
* Add --master-key-file option to luksOpen (open using volume key).
* Fix use of empty keyfile.
* Fix error message for luksClose and detached LUKS header.
* Allow --header for status command to get full info with detached header.
OBS-URL: https://build.opensuse.org/package/show/security/cryptsetup?expand=0&rev=83
* Add selection of random/urandom number generator for luksFormat
(option --use-random and --use-urandom).
* Fix luksRemoveKey to not ask for remaining keyslot passphrase,
only for removed one.
* No longer support luksDelKey (replaced with luksKillSlot).
* if you want to remove particular passphrase, use luksKeyRemove
* if you want to remove particular keyslot, use luksKillSlot
Note that in batch mode luksKillSlot allows removing of any keyslot
without question, in normal mode requires passphrase or keyfile from
other keyslot.
* Default alignment for device (if not overridden by topology info)
is now (multiple of) *1MiB*.
This reflects trends in storage technologies and aligns to the same
defaults for partitions and volume management.
* Allow explicit UUID setting in luksFormat and allow change it later
in luksUUID (--uuid parameter).
* All commands using key file now allows limited read from keyfile using
--keyfile-size and --new-keyfile-size parameters (in bytes).
This change also disallows overloading of --key-size parameter which
is now exclusively used for key size specification (in bits.)
* luksFormat using pre-generated master key now properly allows
using key file (only passphrase was allowed prior to this update).
* Add --dump-master-key option for luksDump to perform volume (master)
key dump. Note that printed information allows accessing device without
passphrase so it must be stored encrypted.
This operation is useful for simple Key Escrow function (volume key and
encryption parameters printed on paper on safe place).
This operation requires passphrase or key file.
