Briefkasten is an open-source electronic mailbox that allows you to receive encrypted messages anonymously on a self-hosted server. In this tutorial, you will learn how to install Briefkasten on Debian Latest.
Before you begin, you need to have the following:
First, you need to install the required dependencies for Briefkasten:
sudo apt-get update
sudo apt-get install python3-pip python3-dev build-essential
sudo apt-get install libssl-dev libffi-dev
sudo apt-get install python3-venv
Next, you need to clone the Briefkasten repository from GitHub:
git clone https://github.com/ndom91/briefkasten.git
After cloning the repository, change the directory to the briefkasten folder:
cd briefkasten
Now, you need to create a Python virtual environment for Briefkasten:
python3 -m venv briefkasten-env
Activate the virtual environment:
source briefkasten-env/bin/activate
Once the virtual environment is activated, install the required packages using pip:
pip install -r requirements.txt
Now, you can start the Briefkasten server by running the following command:
python3 app.py
You should see the server running on http://127.0.0.1:5000/.
Note: You can change the default port number by modifying the app.config['PORT'] value in the app.py file.
If you want to make your Briefkasten server available on the internet, you need to configure Nginx to act as a reverse proxy.
To install Nginx on Debian:
sudo apt-get update
sudo apt-get install nginx
Now, create a new server block configuration file for Briefkasten:
sudo nano /etc/nginx/sites-available/briefkasten
Add the following configuration to this file:
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://127.0.0.1:5000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
Save and close the file.
Create a symbolic link to enable the Briefkasten configuration:
sudo ln -s /etc/nginx/sites-available/briefkasten /etc/nginx/sites-enabled/briefkasten
Test the Nginx configuration:
sudo nginx -t
If there are no errors, reload Nginx:
sudo systemctl reload nginx
Now your Briefkasten server should be accessible via your domain name.
You have successfully installed Briefkasten on Debian Latest and made it accessible to the internet using Nginx as a reverse proxy. You can now start using it to receive encrypted messages anonymously.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
