Toot

Let's say I forgot my disk encryption key (linux, luks, cryptsetup) and have a vague idea with a couple of permutations.

What is the live system I should boot to go through the candidates?

Bonus points if it supports some sort of expression syntax such that it can build the permutations by itself.

@freddy

I would choose Kali Linux (because most important stuff pre-installed).

Extract the header + keys:

cryptsetup luksHeaderBackup --header-backup-file header.img /dev/sdX

"Bruteforce" with hashcat:

hashcat -m 14600 header.img wordlist.txt --rules-file=myrules.rule

@freddy I just tend to boot on the Arch install system. Not sure it has very advanced programming tools, but bash (or is it zsh) would probably work well enough.

@shtrom this seems like SUCH a common use case, I would hope someone would have done the looping and scripting for me. :-)
