Step by step basic installation of Arch Linux with systemd-boot on a UEFI system
Step 1: Partition and format disks
List disks,
iso# fdisk -l
Select disk,
iso# fdisk /dev/X // Replace X with a storage device
// SATA drives: sda, sdb, sdc...
// NVMe drives: nvme0n1, nvme1n1, nvme2n1...
Create a GPT partiton table,
iso[fdisk]# g
Create partitions for ESP, root, and (optionally) swap, // For swapfile, see step 4.5

Process steps for Feistel Cipher and S-DES
Feistel Cipher
Step 1: Split the bits in half, L0 and R0
Step 2: R0 XOR K1 = X1
Step 3: L0 XOR X1 = X2 = R1
Step 4: R0 = L1
Step 5: Repeat for n rounds
S-DES
