+WireGuard Private key command info:
+    sudo chmod go= /etc/wireguard/private.key
+        info: The sudo chmod go=... command removes any permissions 
+        on the file for users and groups other than the root user to 
+        ensure that only it can access the private key.
+
+    sudo cat /etc/wireguard/private.key | wg pubkey | sudo tee /etc/wireguard/public.key
+        This command consists of three individual commands that 
+        are chained together using the | (pipe) operator:
+
+    1.sudo cat /etc/wireguard/private.key: this command reads the private key 
+      file and outputs it to the standard output stream.
+    2.wg pubkey: the second command takes the output from the first command as 
+      its standard input and processes it to generate a public key.
+    3.sudo tee /etc/wireguard/public.key: the final command takes the output 
+      of the public key generation command and redirects it into the file named /etc/wireguard/public.key.
