Boosting Encrypted Persistence Storage on Kali Linux Live USB
In this article, we will discuss how to increase the amount of encrypted persistence storage on a Kali Linux Live USB with LUKS encryption. We will cover the key concepts and provide detailed instructions using subtitles, paragraphs, and code blocks. The code blocks will be properly formatted according to the programming language used, including indentation and tabulation where needed.
Prerequisites
- A USB drive with a minimum capacity of 32GB (in this example, we will use a Sandisk 32GB USB drive)
- The Kali Linux Live USB image
- The
ddcommand line utility - The
cryptsetupcommand line utility
Creating a Persistent Storage on Kali Linux Live USB
To create a persistent storage on Kali Linux Live USB, we need to use the dd command line utility to write the Kali Linux Live USB image to the USB drive. Here is an example command:
dd if=kali-linux-2022.1-live-amd64.iso of=/dev/sdb bs=4M status=progress oflag=sync
Replace /dev/sdb with the correct device path for your USB drive. This command will write the Kali Linux Live USB image to the USB drive, creating a bootable USB drive.
Next, we need to create a persistent storage on the USB drive. To do this, we need to resize the partition on the USB drive to make room for the persistent storage. Here is an example command:
fdisk /dev/sdb
This will launch the fdisk utility for the USB drive. Follow these steps to resize the partition:
- Delete the existing partition (press
dand select the partition number) - Create a new partition (press
nand follow the prompts) - Set the partition type to
W95 FAT32 (LBA)(presstand selectc) - Write the changes to the partition table (press
w)
Next, we need to format the new partition as FAT32. Here is an example command:
mkfs.vfat /dev/sdb1
Replace /dev/sdb1 with the correct device path for the new partition. This will format the new partition as FAT32.
Finally, we need to create the persistent storage. Here is an example command:
mkdir /mnt/usb
mount /dev/sdb1 /mnt/usb
dd if=/dev/zero of=/mnt/usb/persistence.img bs=1M count=512
losetup /dev/loop0 /mnt/usb/persistence.img
cryptsetup luksFormat /dev/loop0
cryptsetup luksOpen /dev/loop0 persistence
mkfs.ext4 /dev/mapper/persistence
mount /dev/mapper/persistence /mnt/usb/persistence
echo "/ union" > /mnt/usb/persistence/persistence.conf
umount /mnt/usb/persistence
cryptsetup luksClose persistence
losetup -d /dev/loop0
This will create a 512MB persistent storage on the USB drive. You can adjust the size of the persistent storage by changing the value of the count parameter in the dd command. This command will also create a file named persistence.img on the USB drive, which will be used to store the persistent data. The persistent storage will be encrypted using LUKS encryption.
Increasing the Amount of Encrypted Persistence Storage
To increase the amount of encrypted persistence storage, we need to resize the persistence.img file on the USB drive. Here is an example command:
dd if=/dev/zero of=/mnt/usb/persistence.img bs=1M seek=1024
This will increase the size of the persistence.img file to 1GB. You can adjust the size of the persistence.img file by changing the value of the seek parameter in the dd command. This command will fill the remaining space on the USB drive with zeros.
Next, we need to resize the ext4 filesystem on the persistence.img file. Here is an example command:
resize2fs /dev/mapper/persistence
This will resize the ext4 filesystem to fill the entire persistence.img file. The encrypted persistence storage is now increased.
- We discussed how to increase the amount of encrypted persistence storage on a Kali Linux Live USB with LUKS encryption.
- We provided detailed instructions on how to create a persistent storage on the USB drive and how to resize it to increase the amount of encrypted persistence storage.
- We used the
dd,fdisk,mkfs.vfat,mkfs.ext4,resize2fs,cryptsetup, andmountcommand line utilities to perform these tasks.
