00:00:00,200 --> 00:00:04,390
in this video, we're going to talk about veracrypt and luke's encrypted volumes.

2
00:00:04,390 --> 00:00:09,090
now both of these are types of implementations to allow for full disk encryption.

3
00:00:09,090 --> 00:00:15,480
so these are the actual hard drives that are on your computer or the usb storage device you have tails installed on.

4
00:00:15,700 --> 00:00:19,170
so let's explore a little bit about these before we dive into tails.

5
00:00:19,170 --> 00:00:23,050
veracrypt is an open source encryption standard and it's multi- platform.

6
00:00:23,050 --> 00:00:25,430
you can put this on linux, windows, and mac.

7
00:00:25,430 --> 00:00:27,090
it's a tool ready to use.

8
00:00:27,090 --> 00:00:33,760
it's used for storage drives or external storage drives, and it helps secure your sensitive data and very easy to use.

9
00:00:33,900 --> 00:00:43,680
essentially, if someone took out your hard drive on your computer, it would be encrypted, meaning they would need that password or some way to decrypt that volume before reading what data was on that hard drive.

10
00:00:43,780 --> 00:00:51,010
comparably, if you don't have encryption on and you have a computer and someone takes that hard drive out, they can read it without needing to do anything.

11
00:00:51,010 --> 00:00:53,770
so you want to make sure you're always encrypting your volumes.

12
00:00:53,770 --> 00:00:58,550
now mac devices and windows devices nowadays all come with encryption built in.

13
00:00:58,550 --> 00:01:07,880
windows has its own version of encryption and mac as well will encrypt your volumes using information like your apple id with its file vault applications.

14
00:01:08,460 --> 00:01:16,520
so those two are already used on those platforms, but if you want an open source one that can be used across multiple platforms, that's where veracrypt would come in.

15
00:01:17,660 --> 00:01:20,310
now veracrypt does differ from luke's a little bit.

16
00:01:20,310 --> 00:01:22,470
this is native to linux itself.

17
00:01:22,470 --> 00:01:24,450
you can do full disk encryption on linux.

18
00:01:24,450 --> 00:01:34,320
tails comes with luke's built in and because we set up tails with persistence and that administrative password, we've actually already set up luke's and we can go take a look at that right now.

19
00:01:34,780 --> 00:01:48,720
okay so here on tails if you want to see information about your disks that are installed you can actually just type in the activity window disks and there you'll see a graphical user interface that points to information about the devices and disks you have on your pc.

20
00:01:49,020 --> 00:01:56,050
so this pc that i'm using plugged in has a 256 gigabyte disk that has partitions on it.

21
00:01:56,050 --> 00:01:58,950
now tails is not using or running on any of this.

22
00:01:58,950 --> 00:02:01,990
tails is actually running off of this usb drive right here.

23
00:02:01,990 --> 00:02:12,550
and you can see right here our persistent volume, right tails is installed right here on the partition one, but then we have the tails data volume right here, partition two, which is the luke's volume.

24
00:02:12,550 --> 00:02:13,470
you can see it right there.

25
00:02:13,470 --> 00:02:15,410
it says luke's encryption version two.

26
00:02:15,410 --> 00:02:19,330
right now it is unlocked because we had to unlock it when we logged in.

27
00:02:19,330 --> 00:02:23,080
that's that entering the password when you log in that we showed earlier in the course.

28
00:02:23,100 --> 00:02:25,610
so this is already encrypted and ready to go.

29
00:02:25,610 --> 00:02:27,730
you already have the luke's encryption set up.

30
00:02:27,730 --> 00:02:35,770
now you could change this if you need, but you can also go here and we can delete this partition on this drive and set up luke's encryption on it if we wanted to.

31
00:02:35,770 --> 00:02:41,850
if we wanted to do that, we would have to format the disk, which i'm not going to do so in this video because i want to keep what's on there.

32
00:02:41,850 --> 00:02:43,030
but that's how you would do it.

33
00:02:43,030 --> 00:02:46,950
you just format the disk and then when you repartition it, you just add encryption.

34
00:02:46,950 --> 00:02:52,150
now we're not going to dive much deeper in this course on partitioning and encryptions.

35
00:02:52,150 --> 00:03:01,170
if you want to learn more about that, we're going to make a separate course on like encryption and cryptography as a whole, especially in tails and tor and all of those tools.

36
00:03:01,170 --> 00:03:03,830
so if you're interested to learn more there, check that out.

37
00:03:03,830 --> 00:03:10,410
but otherwise tails, you already have encryption, you already have luke's when you set up the persistence, so there's not much work needed to be done.

38
00:03:10,410 --> 00:03:17,730
but it is important you understand the concepts of luke's and what veracrypt is and their general purpose, which is just full disk encryption.

39
00:03:17,730 --> 00:03:19,290
if you have any questions, let me know.

40
00:03:19,290 --> 00:03:20,720
otherwise, we'll see you in the next one.
