If your requirement is for the entire system to be encrypted then I think the only is a system rebuild, but if you can convince management that a good compromise is encrypting only the applications and their data, you should be able to add encrypted storage, copy the sensitive files and wipe the old allocations. I have done this for a test system encrypting a MySQL database instance and a web

Hi people, i had created encrypted device with cryptsetup/LUKS which i setup with an ext4 filesystem. This device is an external USB harddisk. When i plugin this device it will be automatically mounted by my gnome3 system (Debian Wheezey/Testing), but this week i got an error. I did ask the ask the LUKS developers what is the problem and they told me that this is an ext4 problem. The error

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I created a LUKS encrypted partition via a udev-triggered script on 6.6 using --key-file /tmp/foo. This worked fine, and I can decrypt the LUKS partition via script and manually using --key-file with luksOpen. The odd problem is that I can't decrypt the partition using the prompt. If I manually create a file with the passphrase in it

Is there an easy way (cli) to enable a luks encrypted partition after reboot (a partition that was not enabled while booting, because not in the crypttab). I can execute the necessary command stack [1] but just wondering if there is an "enterprise/easy" way to do that ... [1] cryptsetup luksOpen $(blkid -t TYPE="crypto_LUKS" -o device) \ luks-$(cryptsetup luksUUID

How do you change the LUKS filesystem password?

Hi everyone, I added a page under the HowTos for Encryption, and then added a guide for encrypting /tmp /swap and /home using cryptsetup and LUKS keys on LVM, when you already have partitions setup. http://wiki.centos.org/HowTos/EncryptTmpSwapHome Regards, Max

You can do that with cryptsetup-reencrypt, but it needs to be able to make space for the ~2MB LUKS header ahead of the filesystem in the

These commits, along with the associated changes to common: https://www.redhat.com/archives/libguestfs/2020-March/msg00286.html support the transparent decryption and inspection of Windows guests encrypted with BitLocker encryption. To do the BitLocker decryption requires cryptsetup 2.3.0 (although cryptsetup 2.3 is not required for existing LUKS use). It also requires a new-ish Linux kernel, I

Original version linked from here: https://bugzilla.redhat.com/show_bug.cgi?id=1808977#c8 There is no change in the code in this series, but feedback from the original series was we shouldn't lose the error message in patch 7. When I tested this just now in fact we don't lose the error if debugging is enabled, but I have updated the commit message to note what the error message is in the

As discussed in the emails today, this is the third version addressing most points from the v1/v2 review. You will need to pair this with the changes in libguestfs-common from this series: https://www.redhat.com/archives/libguestfs/2020-September/msg00050.html Rich.

Hi Chris, thanks for your answer. It is the first time I decided to encrypt my lvm. I choosed to encrypt the volume group, not every logical volume itself, because in case of doing lvm snapshots in that group they will be encrypted too? And how do I create a new encrypted volume group? Regards Tim Am 6. M?rz 2015 01:58:23 MEZ, schrieb Chris Murphy <lists at colorremedies.com>: >On

The following patch attempts to implement sparsification of LUKS-encrypted partitions. It uses lsblk to pair the underlying LUKS block device with its mapped name. Also, --allow-discards was added by default to luks_open(). There are several potential issues that I can think of: 1) If and entire device is encrypted (not just one of more partitions), the lsblk trick might not work. 2) The

I'm sorry, but grep -i crypt /var/log/anaconda/anaconda.program.log returns nothing. But I have got an entry in /etc/crypttab.
