As we have seen here, installing Kali linux is very simple, especially if you do it via usb. In the last guide, the execution method chosen was the live version, therefore a portable version, asy to use, but which does not allow you to save the data of the session just ended. That's why we're going to see persistent mode today, especially its encrypted version.
Let's go more specifically, let's see the differences between the three types:
Live: ready-to-use version, easy to install, the only flaw is any file or change will be lost once the session is terminated.
Persistence: very useful variant if you want to keep all the work done previously, not encrypted.
Persistence (encrypted): similar to the previous version, but everything is encrypted.
Method
USB stick (16 GB minimum)
Network connection
Pc
1 We format our usb.
It is important to delete all the contents from the stick, preferably in FAT32 format.
2 Download the Kali Linux operating system image file.
You will need the operating system image,
you can go to the official download page.
3 Mount the operating system on the flash drive.
To carry out this step you will need the win32imager program.
4 Let's resize the partitions.
We "divide" the memory of our usb. Now right click on our device and click on Resize. 4 Gb will be fine, do as the photo below.
Now let's define the new partition.
At this point we need to create a new partition.
To do this right click on Unallocated.
Then Create, here we should set some options.
In partition label we insert the name of our partition.
In file system we select ext3.
Click on Ok.
Finally on Apply at the top left.
Boot Usb
We insert the flash drive into our PC and modify the boot of our computer.
To do this it is very simple, starting the PC you will have to click one or more keys at startup, each manufacturer has its own combination of keys (F2, F12, F10 and ESC are the most common) here is a list of the most famous manufacturers:
Acer: Del or F2
Asus: F2 Samsung: F2
Lenovo: F1 or F2
HP: F1, F2, F10, Esc or Canc
ou are now in the bios, here you will need to change the boot preferences (boot option) and set as primary to USB.
We encrypt Linux
Started linux, select USB Encrypted Persistence.
Ok, the system is working but not encrypted, to do this we open the terminal:
We type from the terminal:
fdisk -l
You will see different devices with various partitions, make sure you find your Usb.
Here is an example:
Where sdb2 is the persistence created previously (the name of the wording can vary sdb3, sdb4, sdb5 etc)
It is important to specify the partition name, otherwise the encryption will not work. Assuming it is sdb2 we complete everything with this denomination.
After this command there will be a warning message, type YES.
Enter a password, please don't forget it.
When "Command successful" appears, execute the following command:
Let's continue with creating the filesystem:
Complete everything with the following commands:
Finally close the session:
Well we're done, restart everything and check that everything is fine.

/dev/sdb1 2048 8390655 8388608 4G c W95 FAT32 (LBA)

Code:
cryptsetup --verbose --verify-passphrase luksFormat / dev / sdb2After this command there will be a warning message, type YES.

cryptsetup luksOpen / dev / sdb2 my_usbLet's continue with creating the filesystem:
Code:
mkfs.ext3 -L persistence / dev / mapper / my_usb
Code:
e2label / dev / mapper / my_usb persistenceComplete everything with the following commands:
Code:
mkdir -p / mnt / my_usb
mount / dev / mapper / my_usb / mnt / my_usb
echo "/ union"> /mnt/my_usb/persistence.conf
umount / dev / mapper / my_usbFinally close the session:
Code:
cryptsetup luksClose / dev / mapper / my_usbWell we're done, restart everything and check that everything is fine.
