Disk Encryption Configuration Skill

Purpose

This skill reports the current disk encryption configuration on the target system.

What to Report

• Encrypted volumes and their mount points
• Encryption method (LUKS, LUKS2, dm-crypt)
• Cipher and key size in use
• Swap encryption status
• Unencrypted volumes

Commands

List Block Devices

lsblk -o NAME,SIZE,TYPE,FSTYPE,MOUNTPOINT

Check for LUKS Volumes

# List active encrypted mappings
ls -la /dev/mapper/

# Check dm-crypt targets
sudo dmsetup table --target crypt

Get LUKS Details

# For a specific LUKS device
sudo cryptsetup luksDump /dev/sdXn

Key fields to report:

• Version (LUKS1/LUKS2)
• Cipher (e.g., aes-xts-plain64)
• Key size (e.g., 512 bits)

Check Swap Encryption

swapon --show
cat /etc/crypttab | grep swap

Output Format

DISK ENCRYPTION
  Encrypted Volumes:
    /dev/nvme0n1p3: LUKS2 (aes-xts-plain64, 512-bit) → /
    /dev/nvme0n1p4: LUKS2 (aes-xts-plain64, 512-bit) → /home
  Swap: Encrypted / Not Encrypted / No Swap
  Unencrypted Volumes:
    /dev/nvme0n1p1: EFI System Partition (expected)

Dependencies

• cryptsetup package
• dmsetup utility
• lsblk utility
• Root/sudo access for LUKS details
