cryptsetup (2:2.3.7-1+deb11u1) bullseye-security; urgency=high This release fixes a key truncation issue for standalone dm-integrity devices using HMAC integrity protection. For existing such devices with extra long HMAC keys (typically >106 bytes of length, see https://bugs.debian.org/949336#78 for the various corner cases), one might need to manually truncate the key using integritysetup(8)'s `--integrity-key-size` option in order to properly map the device under 2:2.3.7-1+deb11u1. Only standalone dm-integrity devices are affected. dm-crypt devices, including those using authenticated disk encryption, are unaffected. -- Guilhem Moulin Tue, 01 Feb 2022 15:36:35 +0100 cryptsetup (2:1.6.6-1) unstable; urgency=medium The whirlpool hash implementation has been broken in gcrypt until version 1.5.3. This has been fixed in subsequent gcrypt releases. In particular, the gcrypt version that is used by cryptsetup starting with this release, has the bug fixed. Consequently, LUKS containers created with broken whirlpool will fail to open from now on. In the case that you're affected by the whirlpool bug, please read section '8.3 Gcrypt after 1.5.3 breaks Whirlpool' of the cryptsetup FAQ at https://gitlab.com/cryptsetup/cryptsetup/wikis/FrequentlyAskedQuestions carefully. It explains how to open your LUKS container and reencrypt it afterwards. -- Jonas Meurer Tue, 04 Mar 2014 23:17:37 +0100 cryptsetup (2:1.1.3-1) unstable; urgency=low Cryptdisks init scripts changed their behaviour for failures at starting and stopping encrypted devices. Cryptdisks init script now raises a warning for failures at starting encrypted devices, and cryptdisks-early warns about failures at stopping encrypted devices. -- Jonas Meurer Sat, 10 Jul 2010 14:36:33 +0200 cryptsetup (2:1.1.0-1) unstable; urgency=low The default key size for LUKS was changed from 128 to 256 bits, and default plain mode changed from aes-cbc-plain to aes-cbc-essiv:sha256. In case that you use plain mode encryption and don't have set cipher and hash in /etc/crypttab, you should do so now. The new defaults are not backwards compatible. See the manpage for crypttab(5) for further information. If your dm-crypt setup was done by debian-installer, you can ignore that warning. Additionally, the keyscript decrypt_gpg, which was disabled by default up to now, has been rewritten and renamed to decrypt_gnupg. If you use a customized version of the decrypt_gpg keyscript, please backup it before upgrading the package. -- Jonas Meurer Thu, 04 Mar 2010 17:31:40 +0100 cryptsetup (2:1.1.0~rc2-1) unstable; urgency=low The cryptroot initramfs hook script has been changed to include all available crypto kernel modules in case that initramfs-tools is configured with MODULES=most (default). See /etc/initramfs-tools/initramfs.conf for more information. If initramfs-tools is configured with MODULES=dep, the cryptroot hook script still tries to detect required modules, as it did by default in the past. -- Jonas Meurer Sun, 27 Sep 2009 16:49:20 +0200 cryptsetup (2:1.0.7-2) unstable; urgency=low Checkscripts vol_id and un_vol_id have been replaced by blkid and un_blkid. In case that you explicitly set keyscript=vol_id or keyscript=un_vol_id in /etc/crypttab, you will need to update your /etc/crypttab manually. Replacing 'vol_id' with 'blkid' and 'un_vol_id' with 'un_blkid' should work. The new *blkid keyscripts are fully compatible to the old *vol_id scripts. -- Jonas Meurer Sun, 23 Aug 2009 23:32:49 +0200 cryptsetup (2:1.0.6-8) unstable; urgency=low Keyscripts inside the initramfs have been moved from /keyscripts to /lib/cryptsetup/scripts. This way they're now available at the same location as on the normal system. In most cases no manual action is required. Only if you reference a keyscript by path in some script that is included in the initramfs, then you need to update that reference by updating the path. -- Jonas Meurer Tue, 23 Dec 2008 00:43:10 +0100 cryptsetup (2:1.0.6-7) unstable; urgency=medium Support for the timeout option has been removed from cryptdisks initscripts in order to support splash screens and remote shells in boot process. The implementation had been unclean and problematic anyway. If you used the timeout option on headless systems without physical access, then it's a much cleaner solution anyway, to use the 'noauto' option in /etc/crypttab, and start the encrypted devices manually with '/etc/init.d/cryptdisks force-start'. Another approach is to start a minimal ssh-server in the initramfs and unlock the encrypted devices after connecting to it. This even supports encrypted root filesystems for headless server systems. For more information, please see /usr/share/docs/cryptsetup/README.Debian.gz -- Jonas Meurer Tue, 16 Dec 2008 18:37:16 +0100 cryptsetup (2:1.0.6-4) unstable; urgency=medium The obsolete keyscript decrypt_old_ssl and the corresponding example script gen-old-ssl-key have been removed from the package. If you're still using them, either save a local backup of /lib/cryptsetup/scripts/decrypt_old_ssl and put it back after the upgrade finished, or migrate your setup to use keyscripts that are still supported. -- Jonas Meurer Sun, 27 Jul 2008 16:22:57 +0200 cryptsetup (2:1.0.6~pre1+svn45-1) unstable; urgency=low The default hash used by the initramfs cryptroot scripts has been changed from sha256 to ripemd160 for consistency with the cryptsetup default. If you have followed the recommendation to configure the hash in /etc/crypttab this change will have no effect on you. If you set up disk encryption on your system using the Debian installer and/or if you use LUKS encryption, everything is already set up correctly and you don't need to do anything. If you did *not* use the Debian installer and if you have encrypted devices which do *not* use LUKS, you must make sure that the relevant entries in /etc/crypttab contain a hash= setting. -- Jonas Meurer Tue, 29 Jan 2008 11:46:57 +0100 cryptsetup (2:1.0.5-2) unstable; urgency=low The vol_id and un_vol_id check scripts no longer regard minix as a valid filesystem, since random data can be mistakenly identified as a minix filesystem due to an inadequate signature length. If you use minix filesystems, you should not rely on prechecks anymore. -- Jonas Meurer Mon, 10 Sep 2007 14:39:44 +0200 cryptsetup (2:1.0.4+svn16-1) unstable; urgency=high The --key-file=- argument has changed. If a --hash parameter is passed, it will now be honoured. This means that the decrypt_derived keyscript will in some situations create a different key than previously meaning that any swap partitions that rely on the script will have to be recreated. To emulate the old behaviour, make sure that you pass "--hash=plain" to cryptsetup. -- David Härdeman Tue, 21 Nov 2006 21:29:50 +0100 cryptsetup (2:1.0.4-7) unstable; urgency=low The cryptsetup initramfs scripts now also tries to detect swap partitions used for software suspend (swsusp/suspend2/uswsusp) and to set them up during the initramfs stage. See README.initramfs for more details. -- David Härdeman Mon, 13 Nov 2006 19:27:02 +0100 cryptsetup (2:1.0.4-1) unstable; urgency=low The ssl and gpg options in /etc/crypttab have been deprecated in favour of the keyscripts option. The options will still work, but generate warnings. You should change any lines containing these options to use keyscript=/lib/cryptsetup/scripts/decrypt_old_ssl or keyscript=/lib/cryptsetup/scripts/decrypt_gpg instead as support will be completely removed in the future. -- David Härdeman Mon, 16 Oct 2006 00:00:12 +0200 cryptsetup (2:1.0.3-4) unstable; urgency=low Up to now, the us keymap was loaded at the passphrase prompt in the boot process and ASCII characters were always used. With this upload this is fixed, meaning that the correct keymap is loaded and the keyboard is (optionally) set to UTF8 mode before the passphrase prompt. This may result in your password not working any more in the boot process. In this case, you should add a new key with cryptsetup luksAddKey with your correct keymap loaded. Additionally, all four fields are now mandatory in /etc/crypttab. An entry which does not contain all fields will be ignored. It is recommended to set cipher, size and hash anyway, as defaults may change in the future. If you didn't set any of these settings yet, then you should add cipher=aes-cbc-plain,size=128,hash=ripemd160 to the the options in /etc/crypttab. See man crypttab(5) for more details. -- David Härdeman Sat, 19 Aug 2006 18:08:40 +0200 cryptsetup (2:1.0.2+1.0.3-rc2-2) unstable; urgency=low The crypttab 'retry' has been renamed to 'tries' to reflect upstream's functionality. Default is 3 tries now, even if the option is not given. See the crypttab.5 manpage for more information. -- Jonas Meurer Fri, 28 Apr 2006 17:42:15 +0200 cryptsetup (2:1.0.2+1.0.3-rc2-1) unstable; urgency=low Since release 2:1.0.1-9, the cryptsetup package uses cryptsetup-luks as upstream source. This is a enhanced version of plain cryptsetup which includes support for the LUKS extension, a standard on-disk format for hard disk encryption. Plain dm-crypt (as provided by the old cryptsetup package) is still available, thus backwards compatibility is given. Nevertheless it is recommended to update your encrypted partitions to LUKS, as this implementation is more secure than the plain dm-crypt. Another major change is the check option for crypttab. It allows to configure checks that are run after cryptsetup has been invoked, and prechecks to be run against the source device before cryptsetup has been invoked. See man crypttab(5) or README.Debian for more information. -- Jonas Meurer Fri, 3 Feb 2006 13:41:35 +0100
