Tor can free people from the necessity of a domain, in addition to helping protect their privacy. As Pleroma's goal is to empower the people and let as many as possible host an instance with as little resources as possible, the ability to host an instance with a small, cheap computer like a RaspberryPi along with Tor, would be a great way to achieve that.
In addition, federating with such instances will also help furthering that goal.
This is a guide to show you how it can be easily done.
This guide assumes you already got Pleroma working, and that it's running on the default port 4000.
Currently only has an Nginx example.
To install Tor on Debian / Ubuntu:
```
apt -yq install tor
```
If using an old server version (older than Debian Stretch or Ubuntu 18.04), install from backports or PPA.
I recommend using a newer server version instead.
To have the newest, V3 onion addresses (which I recommend) in Debian, install Tor from backports.
If you do not have backports, uncomment the stretch-backports links at the end of `/etc/apt/sources.list`.
Then install:
```
apt update
apt -t stretch-backports -yq install tor
```
**WARNING:** Onion instances not using a Tor version supporting V3 addresses will not be able to federate with you.
Create the hidden service for your Pleroma instance in `/etc/tor/torrc`:
In yourPleroma directory, assuming you're running prod,
run the following:
```
su pleroma
MIX_ENV=prod mix deps.get
MIX_ENV=prod mix ecto.migrate
exit
```
restart Pleroma (if using systemd):
```
systemctl restart pleroma
```
# Tor Instance Access
Make your instance accessible using Tor.
## Tor-only Instance
If creating a Tor-only instance, open `config/prod.secret.exs` and under "config :pleroma, Pleroma.Web.Endpoint," edit "https" and "port: 443" to the following:
For both cases, disable CSP in Pleroma's config (STS is disabled by default) so you can define those yourself separately from the clearnet (if your instance is also on the clearnet).
You should now be able to both access your instance using Tor and federate with other Tor instances!

### Possible Issues
* In Debian, make sure your hidden service folder `/var/lib/tor/pleroma_hidden_service/` and its contents, has debian-tor as both owner and group by using
