TorTiPi is a tool to setup the Tor based wifi hotspot on Raspberry Pi (Model 3). This tool can also work with the other models on Raspberry but would require exteranl wifi adapter plugged into RP, which would be helpful to create access point.
At this point TTP provides extremly simple but complete setup to create Tor network access point.
I will not mention that why should one use Tor if you are curious to know this blog post is a good read.
If you really want to get your hands dirty with anonymity, then lets gets started.

Raspberry Pi OS download: https://downloads.raspberrypi.org/

Raspios Buster Armhf Lite

The hostapd.config file in this repo needs to be changed before the running setup script.

interface=wlan0
ssid=TortiPi
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=changeme
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

If you notice the content are very simple key value pair. For our concern we need to focus on ssid and wpa_passphrase. The first one specifies the name of your wifi hotspot and the latter one chnages the password for AP. Once the changes have been made, save the file and run ./setup.sh.
If you have already ran setup script. Donot rerun the script after changing. Rather modify the file /etc/hostapd/hostapd.conf. This file also have same parameter as to the one in hostapd.config. After making the changes restart the hostapd service.
service hostapd restart

TorTiPi setups everything for you. But How ??

sudo apt install git -y && git clone https://github.com/bobtus/tortipi.git && cd tortipi && sudo chmod +x setup.sh
sudo ./setup.sh

At the end of the installation, a Access point named as TorTiPi will be up and its default password would be changeme. If you want to change deafult password, TorTiPi simplifies that too for you.
