So I’ve been reading more on cryptsetup man page and found this interesting excerpt:
If the header of a LUKS volume gets damaged, all data is permanently lost unless you have a header-backup. If a key-slot is damaged, it can only be restored from a header-backup or if another active key-slot with known passphrase is undamaged. Damaging the LUKS header is something people manage to do with surprising frequency. This risk is the result of a trade-off between security and safety, as LUKS is designed for fast and secure wiping by just overwriting header and key-slot area.

Yesterday I wrote about How to create an encrypted LUKS disk image.
Today I wanted to experiment more with it. I wanted to try resizing a LUKS volume, and after one failed attempt I found a way. If you still have the disk image of yesterday’s example, just follow me. 🙂

This could be a great alternative if you have used TrueCrypt encrypted volumes.
I’ve been a TrueCrypt lover for a long time, even after it was allegedly killed. But now I’m starting to think that it’s not a good option for long term safekeeping of my memories. At time point in a future release of Linux if dependencies for TrueCrypt stop working that’s death to my archives. Fortunately we have LUKS since 2004! After using LUKS for a couple of years I think it’s very reliable.

I came across a hard disk with a corrupted MBR. In other words, I found a hard disk that lost all of its partitions but files and folders are still there. Tool of my choice in this kind of cases is TestDisk.

After a lengthy JIRA tip, I’m about to blog a Keyboard Ninja tip for users who do a lot of Ctrl + R thingy to navigate Bash history.

Wunderlist again. Currently this is the only Microsoft thing that I use – apart of Windows servers involved in my DevOps job.

Wunderlist killed its app for Ubuntu long time back.
And then it was bought by Microsoft, so I hardly think there will be a Linux app ever again. For a long time I didn’t use Wunderlist, but I thought of giving it a try once again. I figured out that pinning Wunderlist tab on Firefox works to some extent.
