This option can be used for situations when you need + temporary wipe encryption key (like suspend to RAM etc.) + Please read man page for more information. + + * New --master-key-file option for luksFormat and luksAddKey. + + User can now specify pre-generated master key in file, which allows regenerating + LUKS header or add key with only master key knowledge. + + * Uses libgcrypt and enables all gcrypt hash algorithms for LUKS through -h luksFormat option. + + Please note that using different hash for LUKS header make device incompatible with + old cryptsetup releases. + + * Introduces --debug parameter. + + Use when reporting bugs (just run cryptsetup with --debug and attach output + to issue report.) Sensitive data are never printed to this log. + + * Moves command successful messages to verbose level. + + * Requires device-mapper library and libgcrypt to build. + + * Uses dm-uuid for all crypt devices, contains device type and name now. + + * Removes support for dangerous non-exclusive option + (it is ignored now, LUKS device must be always opened exclusive) + +Other changes: +~~~~~~~~~~~~~~ + * Fixed localization to work again. Also cryptsetup is now translated by translationproject.org. + * Fix some libcryptsetup problems, including + * exported symbols and versions in libcryptsetup (properly use versioned symbols) + * Add crypt_log library function. + * Add CRYPT_ prefix to enum defined in libcryptsetup.h. + * Move duplicate Command failed message to verbose level (error is printed always). + * Fix several problems in build system + * use autopoint and clean gettext processing. + * Check in configure if selinux libraries are required in static version. + * Fix build for non-standard location of gcrypt library. + * Add temporary debug code to find processes locking internal device. + * Fix error handling during reading passphrase. + * Fail passphrase read if piped input no longer exists. + * Fix man page to not require --size which expands to device size by default. + * Clean up Makefiles and configure script. + * Try to read first sector from device to properly check that device is ready. + * Move memory locking and dm initialization to command layer. + * Increase priority of process if memory is locked. + * Add log macros and make logging more consistent. + * Keyfile now must be provided by path, only stdin file descriptor is used (api only). + * Do not call isatty() on closed keyfile descriptor. + * Move key slot manipulation function into LUKS specific code. + * Replace global options struct with separate parameters in helper functions. + * Implement old API calls using new functions. + * Allow using passphrase provided in options struct for LuksOpen. + * Allow restrict keys size in LuksOpen. + * Fix errors when compiled with LUKS_DEBUG. + * Print error when getline fails. + * Completely remove internal SHA1 implementation code, not needed anymore. + * Pad luks header to 512 sector size. + * Rework read/write blockwise to not split operation to many pieces. + * Use posix_memalign if available. + * Fix segfault if provided slot in luksKillslot is invalid. + * Remove unneeded timeout when remove of temporary device succeeded. |
