christiangenco / How to bruteforce a TrueCrypt volume
Last active Jul 15, 2019
Brute force a TrueCrypt volume password with a known list on Mac OS X (works similarly on linux/ubuntu)
View How to bruteforce a TrueCrypt volume
# First you need to know the name of your TrueCrypt disk. In this example, after running the `diskutil list` command,
# you can see that my 2TB TrueCrypt disk is mounted at /dev/disk2, and the encrypted partition is named "disk2s1"
# (see the IDENTIFIER column). That's the name I need to use in the ruby script.
$ diskutil list

# If you, like me, have always known about this `awk` thing
# when stealing one liners from Stack Overflow but always put
# off actually learning it, here's your 10 second lesson:
# Print lines in FILENAME that match pattern (the $0 is a
# variable that refers to the entire line, and can be omitted
# by default):
$ awk '/pattern/{print $0}' FILENAME
# ex: find all words that start with a capital A in the dictionary:
View I before E, except after

Like in belIEve, fIErce, collIE, dIE, or frIEnd.

But flip "ie" if it's after C, like in deCEIve, CEIling, reCEIpt, or CEIlidh.

There are a few exceptions to this rule, though, like in speCIEs, sCIEnce, suffiCIEnt, or sEIze, wEIrd, vEIn, thEIr, forEIgn, or fEIsty.

In fact, in the default dictionary for Mac OS X 10.10, there are 2717 exceptions to this rule, and only 3901 words that follow it (full list below).

In other words: if you're trying to decide if a word should be spelled with "ie" or "ei," following this rule will only help you guess correctly 6 times out of 10.
