## Email encryption

One way to make safe communication is by email encryption.

### Thunderbird / Icedove

Under account settings -> end-to-end encryption, you can manage your public private keypair for communication.

There is an option to generate a new key.

## Guerilla infrastructure

We are installing mobile infrastructure on a [Raspberry PI model 3](https://www.raspberrypi.com/products/raspberry-pi-3-model-b/).

[Yunohost](https://yunohost.org/en/install) is a nice package sitting on top of [debian linux](https://www.debian.org) which simplifies system administration a lot. It installs a working web server, LDAP directory with a nice web UI for user / application administration.

## Installation

First we flash the install image on microsd card.

    sudo dd if=2022-12-06-yunohost-lite.img of=/dev/sdc bs=1M && sudo sync
    
Careful that you get the `of=` part right; if you miss a letter you could break your operating system's partition and lose data.

Then we put the card in the raspberry.

Find the raspberry's IP address.
We connected it via a switch to a computer that runs a DHCP server (on 192.168.1.0/24).

A nmap scan revealed the raspberry's IP address, `192.168.1.109`:

    g1smo@dbn ~ » sudo nmap -sP 192.168.1.0/24      
    Starting Nmap 7.93 ( https://nmap.org ) at 2023-07-07 18:54 CEST
    Nmap scan report for 192.168.1.109
    Host is up (0.00047s latency).
    MAC Address: B8:27:EB:F5:31:56 (Raspberry Pi Foundation)
    Nmap scan report for dbn (192.168.1.100)
    Host is up.
    Nmap done: 256 IP addresses (2 hosts up) scanned in 4.27 seconds

So we put the IP address in a web browser to finish setting up yunohost with the configuration wizard.

### set main domain

We registered a domain name bask.kompot.si for this occasion.

Next we set an admin password (`letmein`).

When the installation finishes, we go back to the IP address `192.168.1.109`, since it's not really on the internet yet.

We use the nice web UI to create a users, `bask`, and set a password for it, `properteaistheft`.

Next, we click on "Manage groups and permissins" on the user management page and add the "SSH" permission to the `bask` user. This way we can use SSH to log into the raspberry: `ssh bask@192.168.1.109`.

We `su` to root and add our `bask` user to the `sudo group`, giving it administration privileges: `gpasswd -a bask sudo`.

Then we close the terminal and login via ssh again.

### Unblock wifi

We unblock the wifi, running `sudo raspi-config`.

First we set the geographical zone for wireless compliance with regulation: `1. System options > S1 Wireless LAN > SI (Slovenia)`. Or we do not do that ;) (You can also choose a random country really)

Then we enter the SSID and password for a hotspot with internet access.
