# Anonymity - Easy Anonymous Chats Using SimpleX (and onion-only servers)
|
||||
|
||||

|
||||
|
||||
In this tutorial we're going to see how to setup a chat application for Anonymous use. This is especially important in a world where mass-surveillance is nearly-omnipresent. It has become the end users' responsibility to uphold their privacy and anonymity while communicating online.
|
||||
|
||||
|
||||
|
||||
## **Choosing the most appropriate chat application**
|
||||
|
||||
In order to choose the most appropriate messaging app for our intended use (Anonymity), we have the following requirements:
|
||||
|
||||
_Privacy:_
|
||||
|
||||
1. The application must be free and open source (FOSS)
|
||||
|
||||
2. The application must have End to End Encryption by default (E2EE)
|
||||
|
||||
3. The application must allow us to run and use our own servers (Decentralisation)
|
||||
|
||||
|
||||
|
||||
|
||||
_Anonymity:_
|
||||
|
||||
1. The application must support Tor .onion servers out of the box
|
||||
|
||||
2. The application must allow you to chat without requiring any information (no emails, no usernames, no phone numbers)
|
||||
|
||||
3. The application must have the ability for us to join chatrooms without revealing our identity (Incognito Mode)
|
||||
|
||||
|
||||
|
||||
|
||||
_Deniability:_
|
||||
|
||||
1. The application must have disappearing messages (Deniability)
|
||||
|
||||
|
||||
|
||||
|
||||
You'd be suprised to see that as of right now (November 2024) there is only SimpleX that actually fits all of these criterias. therefore that's what we'll use for Anonymous chats.
|
||||
|
||||
## _Mobile OPSEC Recommendations:_
|
||||
|
||||
1. Hardware : Google Pixel Phone
|
||||
|
||||
2. Host OS: [GrapheneOS](../graphene/index.md)
|
||||
|
||||
3. Graphene Profile: Anonymous Use
|
||||
|
||||
4. Applications: Orbot and SimpleX
|
||||
|
||||
|
||||
|
||||
|
||||
## _Desktop OPSEC Recommendations:_
|
||||
|
||||
1. Hardware : (Personal Computer / Laptop)
|
||||
|
||||
2. Host OS: [Linux](../linux/index.md)
|
||||
|
||||
3. Hypervisor: [libvirtd QEMU/KVM](../hypervisorsetup/index.md)
|
||||
|
||||
4. Virtual Machine: [Linux](../hypervisorsetup/index.md) or [Whonix](../whonixqemuvms/index.md) or [Tails](../tailsqemuvm/index.md)
|
||||
|
||||
5. Application: Tor (if not on Whonix or Tails), and SimpleX
|
||||
|
||||
|
||||
|
||||
|
||||
We will be going through how to set up your own SimpleX server through Tor, and how to configure your Android client to route your traffic through it.
|
||||
|
||||
## **How to Set Up Anonymous Chats**
|
||||
|
||||
### **Step 1. Option A: GNU/Linux**
|
||||
|
||||
First, update your package list and install Tor by running the following commands in your terminal:
|
||||
|
||||
|
||||
sudo apt update
|
||||
sudo apt install tor
|
||||
|
||||
Once installed, start the Tor service:
|
||||
|
||||
|
||||
sudo systemctl start tor@default
|
||||
|
||||
Next you'll need to download SimpleX AppImage which can be [found here on SimpleX website](https://simplex.chat/downloads/).
|
||||
|
||||
Open a terminal in the directory of your downloaded AppImage. Make the AppImage executable, then launch it:
|
||||
|
||||
|
||||
[ mainpc ] [ /dev/pts/26 ] [~]
|
||||
→ chmod +x simplex-desktop-x86_64.AppImage
|
||||
|
||||
[ mainpc ] [ /dev/pts/26 ] [~]
|
||||
→ ./simplex-desktop-x86_64.AppImage
|
||||
|
||||
|
||||
|
||||
### **Step 1. Option B: Android**
|
||||
|
||||
Download and install the Orbot .apk from [the GitHub repository](https://github.com/guardianproject/orbot/releases).
|
||||
|
||||

|
||||
|
||||
Open Orbot, and in the bottom-right corner, tap on **More** , then **Settings** to enter the settings.
|
||||
|
||||
In the settings menu, scroll down and enable the **Power User Mode**.
|
||||
|
||||
After enabling Power User Mode, go back to the More section and press **Choose apps** and select SimpleX in the list. Go back to **Connect** in the bottom navigation menu and press **Connect**.
|
||||
|
||||

|
||||
|
||||
Download and install [SimpleX using F-Droid](https://f-droid.org/packages/chat.simplex.app/)
|
||||
|
||||

|
||||
|
||||
### **Step 2.**
|
||||
|
||||
Navigate through the setup process, select your username, and press Create. The screenshots showcase the process for Android, but the steps are identical for Linux/GNU as well.
|
||||
|
||||

|
||||
|
||||
Once you've created your profile, open the kebab menu on the bottom left and open **Settings > Network and servers** and activate SOCKS Proxy. Press **SOCKS proxy settings** and set your port to 9050, then save.
|
||||
|
||||
 
|
||||
|
||||
### **You have now successfully configured SimpleX to use Tor!**
|
||||
|
||||
## **Only using your own onion-only simplex server doesn't isolate you.**
|
||||
|
||||
A common misconception that people seem to have is that you wouldnt be able to communicate with regular simplex users that don't have Tor connectivity, when you're only using your own onion-only simplex servers. **But that's not true, you're not even isolated when using onion-only servers.** This mode of thinking comes the fact that traditional federated apps (like the fediverse) don't care about serverside anonymity. But, lucky for us, the official simplex servers also allow Tor connections in between simplex servers, which makes this whole setup possible.
|
||||
|
||||

|
||||
|
||||
In reality, thanks to Simplex's Private Routing protocol, (which is a 2 hop routing protocol), **your trusted simplex server (which is onion-only) communicates with the other party's trusted simplex server, as long as they have Tor connectivity.** And if the other peer is using the default Simplex Servers, which all have Tor connectivity, then they can still communicate to your own onion-only simplex server, which ensures that you're not isolated when you want to have a public, yet anonymous community [like the one we have at Nowhere.](http://nowherejezfoltodf4jiyl6r56jnzintap5vyjlia7fkirfsnfizflqd.onion/simplex.html)
|
||||
|
||||
That's what we are going for in this tutorial. We're going to setup a simplex server that is onion-only, to protect the serverside anonymity, **and we'll use our simplex client to only connect through our onion-only simplex server, and we'll create groupchats with it so that we can have our own public, yet anonymous chatroom.**
|
||||
|
||||
## **Step 3. SimpleX Server Setup**
|
||||
|
||||
It's important to note that in theory, it doesn't matter which SimpleX server you connect to, as all communications are end-to-end encrypted. When you connect via Tor, it further ensures that the server itself won't be able to trace your connection back to you. Your anonymity is maintained through the use of Tor, and your conversations are protected by SimpleX's encryption.
|
||||
|
||||
We're going to make use of [HackLiberty's tutorial](https://forum.hackliberty.org/t/simplex-server-docker-installation-guide-smp-xftp/140) on how to install and configure a SimpleX server using Docker.
|
||||
|
||||
First we're going to create the docker-compose.yml file and the .env file as follows:
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ cat docker-compose.yml

|

- QUOTA=150gb #change to set your own quota
|
||||
networks:
|

|
||||
security_opt:
|

|

|
||||
|
||||

|

|

|

|
||||

|
||||
|
||||
[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]
|
||||
→ cat .env
|
||||
SIMPLEX_ADDR="nowhere" #If using FDQN, make sure to set DNS record
|
||||
SIMPLEX_PASSWORD="dawiuhwaihyawy4129y89u0u1"
|
||||
XFTP_ADDR="nowhere" #If using FDQN, make sure to set DNS record
|
||||
#yes no clearnet at all
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
Then we're going to create the folders as follows:
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ mkdir -p {xftp,smp}/{config,logs}
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ tree .

|

→ mkdir -p tor-data/torrc
|
||||
|

[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ mkdir -p tor-data/{simplex-xftp,simplex-smp}
|
||||
|

|

→ mkdir -p {xftp,smp}/{config,logs}
|
||||

|
||||
→ chmod 700 tor-data/simplex-xftp
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ chmod 700 tor-data/simplex-smp
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ sudo chown 100:65533 tor-data/simplex-xftp
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ sudo chown 100:65533 tor-data/simplex-smp
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ chown -R 100:65533 tor-data/
|
||||
|
||||
chmod 777 -R smp
|
||||
chmod 777 -R xftp
|
||||
|
||||
|
||||
|
||||
Be aware that [SimpleX's documentation]() doesn't recommend by default that the servers be anonymous, they only care about the users being anonymous, that's why they recommend these 3 lines in the torrc configuration:
|
||||
|
||||
|
||||
SOCKSPort 0
|
||||
HiddenServiceNonAnonymousMode 1
|
||||
HiddenServiceSingleHopMode 1
|
||||
|
||||
|
||||
|
||||
**DO NOT USE THESE, otherwise your servers' location will be known. You need to use the following instead:**
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]
|
||||
→ vim tor-data/torrc/torrc
|
||||
|
||||
[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]
|
||||
→ cat tor-data/torrc/torrc
|
||||
SOCKSPort 0.0.0.0:9050
|
||||
HiddenServiceDir /var/lib/tor/simplex-smp
|
||||
HiddenServicePort 5223 simplex-smp:5223
|
||||
HiddenServicePort 80 simplex-smp:80
|
||||
HiddenServiceDir /var/lib/tor/simplex-xftp
|
||||
HiddenServicePort 5233 simplex-xftp:5233
|
||||
|
||||
|
||||
|
||||
Then we're going to run the docker containers so that it creates the tor hostnames for both the smp and xftp services, so that we can use both in the .env file:
|
||||
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ docker-compose up
|
||||
|
||||
[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]
|
||||
→ tree tor-data

|
||||
|

|
||||
→ cat tor-data/simplex-xftp/hostname
|
||||
wg54vc6p3dscshywvt2wninachqoarrodtunapds7t7p47sn5e3qonid.onion
|
||||
|
||||
[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]
|
||||
→ vim .env
|
||||
|
||||
[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]
|
||||
→ cat .env
|
||||
SIMPLEX_ADDR="b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion" #If using FDQN, make sure to set DNS record
|
||||
SIMPLEX_PASSWORD="dawiuhwaihyawy4129y89u0u1"
|
||||
XFTP_ADDR="wg54vc6p3dscshywvt2wninachqoarrodtunapds7t7p47sn5e3qonid.onion" #If using FDQN, make sure to set DNS record
|
||||
|
||||
|
||||
|
||||
|
||||
Then we'll save both the private keys in our keepass and then shred them:
|
||||
|
||||
|
||||
#save both the private keys it in your keepass and then shred it
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ cat smp/config/ca.key
|
||||
-----BEGIN PRIVATE KEY-----
|
||||
REDACTED
|
||||
-----END PRIVATE KEY-----
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ shred -u smp/config/ca.key
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ cat xftp/config/ca.key
|
||||
-----BEGIN PRIVATE KEY-----
|
||||
REDACTED
|
||||
-----END PRIVATE KEY-----
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ shred -u xftp/config/ca.key
|
||||
|
||||
|
||||
|
||||
|
||||
Then we edit the smp config correctly as we will NOT use the clearnet at all, the config parts regarding port 443 https are to be commented.
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ cat smp/config/smp-server.ini | tail -n3
|
||||
#https: 443
|
||||
#cert: /etc/opt/simplex/web.crt
|
||||
#key: /etc/opt/simplex/web.key
|
||||
|
||||
[TRANSPORT]
|
||||
# Host is only used to print server address on start.
|
||||
# You can specify multiple server ports.
|
||||
host: b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion
|
||||
#port: 5223,443 ## we dont need 443!
|
||||
port: 5223
|
||||
log_tls_errors: off
|
||||
|
||||
|
||||
|
||||
Then we also configure it so that the simplex smp server goes through the docker tor daemon to connect to other servers:
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ vim smp/config/smp-server.ini
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ cat smp/config/smp-server.ini
|
||||
|
||||
[PROXY]
|
||||
# Network configuration for SMP proxy client.
|
||||
# `host_mode` can be 'public' (default) or 'onion'.
|
||||
# It defines prefferred hostname for destination servers with multiple hostnames.
|
||||
host_mode: onion
|
||||
required_host_mode: off
|
||||
|
||||
# The domain suffixes of the relays you operate (space-separated) to count as separate proxy statistics.
|
||||
# own_server_domains:

||||
|
||||
# SOCKS proxy port for forwarding messages to destination servers.
|
||||
# You may need a separate instance of SOCKS proxy for incoming single-hop requests.
|
||||
socks_proxy: 10.6.0.4:9050
|
||||
#socks_proxy: tor-simplex:9050
|
||||
|
||||
# `socks_mode` can be 'onion' for SOCKS proxy to be used for .onion destination hosts only (default)
|
||||
# or 'always' to be used for all destination hosts (can be used if it is an .onion server).
|
||||
socks_mode: always
|
||||
|
||||
# Limit number of threads a client can spawn to process proxy commands in parrallel.
|
||||
# client_concurrency: 32
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ vim xftp/config/file-server.ini
|
||||
|

|

Then we simply run the docker containers again:
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
|
||||
→ docker-compose down ; docker-compose up -d
|
||||
|
||||
Starting simplex-xftp ... done
|
||||
Starting simplex-smp ... done
|
||||
Starting tor-simplex ... done
|
||||
|
||||
simplex-smp | Server address: smp://BD4qkVq8lJUgjHt0kUaxeQBYsKaxDejeecxm6-2vOwI=@nowhere
|
||||
simplex-xftp | Server address: xftp://emX7ForsbdpIscNiDZ6b0HTbfFUayn00C1wmeVTofYA=@nowhere
|
||||
|
||||
**#need to manually change the @nowhere to be the onion urls:
|
||||
smp://BD4qkVq8lJUgjHt0kUaxeQBYsKaxDejeecxm6-2vOwI=@b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion
|
||||

|
||||
|
||||
|
||||
|
||||
_Sidenote:_ One important thing to note though is that you shouldn't be the only one to use your own simplex servers as if you are the only one to use that one simplex server, people may figure out that you're the same person when trying to use different profiles. This is why you should list your simplex servers publicly somewhere, either in your own community like i did [here](http://nowherejezfoltodf4jiyl6r56jnzintap5vyjlia7fkirfsnfizflqd.onion/simplex.html):
|
||||
|
||||

|
||||
|
||||
Or you can list your simplex servers on public lists like this one:
|
||||
|
||||

|
||||
|
||||
Optional but recommended: Since you are using docker containers, you can easily automate keeping them updated with a simple cronjob:
|
||||
|
||||
|
||||
[ Wonderland ] [ /dev/pts/4 ] [~]
|
||||
→ crontab -e
|
||||
|
||||
#daily simplex containers update
|
||||
0 0 * * * docker-compose -f /srv/simplex/docker-compose.yml pull ; docker-compose -f /srv/simplex/docker-compose.yml down; docker-compose -f /srv/simplex/docker-compose.yml up -d
|
||||
|
||||
|
||||
|
||||
Once that's done, we can go ahead and add the servers in our simplex client:
|
||||
|
||||
## **Step 4: Configure SimpleX To Use Your Server**
|
||||
|
||||
Now from our simplex client we need to make sure that we are using our own simplex servers, which have the following URL:
|
||||
|
||||
|
||||
SMP server:
|
||||
smp://BD4qkVq8lJUgjHt0kUaxeQBYsKaxDejeecxm6-2vOwI=@b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion
|
||||
|
||||
XFTP server:
|
||||
xftp://emX7ForsbdpIscNiDZ6b0HTbfFUayn00C1wmeVTofYA=@wg54vc6p3dscshywvt2wninachqoarrodtunapds7t7p47sn5e3qonid.onion:5233
|
||||
|
||||
|
||||
|
||||
`        
|
||||
|
||||
And now that our simplex client is ONLY using our onion-only simplex servers, we can create our own chatrooms:
|
||||
|
||||
## **How to Create Chatrooms in Incognito mode**
|
||||
|
||||
Now that we are using our own simplex servers, we can create a chatrooms in incognito mode (meaning that our username will simply be a random noun and adjective):
|
||||
|
||||
  
|
||||
|
||||
Enter a name for your group. You can also add a photo for the group.
|
||||
|
||||
Tick the **Incognito** option. Doing this ensures your profile name and image is hidden from your group members and allows for anonymous connections with other people without shared data. Once you have filled out the necessary information, press **Create group**.
|
||||
|
||||

|
||||
|
||||
as noted above, since you are only using tor-only simplex servers, **this means that you are forcing the users to use Tor to be able to join your invite links.** Here's what the invite link looks like:
|
||||
|
||||
|
||||
https://simplex.chat/contact#/?v=2-7&smp;=smp%3A%2F%2FBD4qkVq8lJUgjHt0kUaxeQBYsKaxDejeecxm6-2vOwI%3D%40**b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion** %2FSMvbQfvtczzC7r6Sv3gEgy_s01_ZYPh_%23%2F%3Fv%3D1-3%26dh%3DMCowBQYDK2VuAyEA9kSAhfaJMzC8YWZzkpoCL8mnBmq2U8VE8_v5HYk0nyE%253D&data;=%7B%22groupLinkId%22%3A%22zjrwnXSNIBJO9ZhoHcRRkQ%3D%3D%22%7D
|
||||
|
||||
|
||||
|
||||
as you can see the default invite link looks like that, and as you can see the onion server address appears in the link, which is the reason why if the user that wants to join doesnt have tor connectivity, he won't be able to join. If you don't want to use any of simplex's servers, you can simply replace the **https://simplex.chat/** at the beginning with your simplex smp server onion url as follows:
|
||||
|
||||
|
||||
**http://b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion/** contact#/?v=2-7&smp;=smp%3A%2F%2FBD4qkVq8lJUgjHt0kUaxeQBYsKaxDejeecxm6-2vOwI%3D%40b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion%2FSMvbQfvtczzC7r6Sv3gEgy_s01_ZYPh_%23%2F%3Fv%3D1-3%26dh%3DMCowBQYDK2VuAyEA9kSAhfaJMzC8YWZzkpoCL8mnBmq2U8VE8_v5HYk0nyE%253D&data;=%7B%22groupLinkId%22%3A%22zjrwnXSNIBJO9ZhoHcRRkQ%3D%3D%22%7D
|
||||
|
||||
|
||||
|
||||
` 
|
||||
|
||||
If you want to not contact any simplex server to be able to view the invite link, you can simply replace the server address to **simplex:/** , which will transform the link as follows:
|
||||
|
||||
|
||||
**simplex:/** contact#/?v=2-7&smp;=smp%3A%2F%2FBD4qkVq8lJUgjHt0kUaxeQBYsKaxDejeecxm6-2vOwI%3D%40b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion%2FSMvbQfvtczzC7r6Sv3gEgy_s01_ZYPh_%23%2F%3Fv%3D1-3%26dh%3DMCowBQYDK2VuAyEA9kSAhfaJMzC8YWZzkpoCL8mnBmq2U8VE8_v5HYk0nyE%253D&data;=%7B%22groupLinkId%22%3A%22zjrwnXSNIBJO9ZhoHcRRkQ%3D%3D%22%7D
|
||||
|
||||
|
||||
|
||||
## **How to Join Chatrooms in Incognito mode**
|
||||
|
||||
If you have received an invite to a SimpleX chatroom, you can join it by pressing the input field at the bottom of the screen labeled **Search or paste SimpleX link**.
|
||||
|
||||
Paste your invite link into the input field and press **Enter**.
|
||||
|
||||

|
||||
|
||||
You will be met with a window asking wheter you'd like to connect using your current profile or using an Incognito profile.
|
||||
|
||||
Select **Use new incognito profile**.
|
||||
|
||||
This is because we don't want to reveal what our simplex username is, we just want to join the chatroom using a random username that is not tied to our identity.
|
||||
|
||||

|
||||
|
||||
And there as you can see, everyone that joins in in incognito gets a random pseudonym with the format "Random Adjective Random Word" effectively helping the users maintain their anonymity while in the chat.
|
||||
|
||||

|
||||
|
||||
## **Conclusion**
|
||||
|
||||
By following this tutorial, you've set up a secure, anonymous chat system using SimpleX and Tor. You've learned how to install Orbot, configure SimpleX servers with `.onion` addresses, create incognito chatrooms, and join them anonymously. This setup ensures that your private conversations remain secure and untraceable.
|
||||
|
||||
### **What You've Accomplished**
|
||||
|
||||
- Installed Orbot and routed traffic through the Tor network.
|
||||
- Configured SimpleX servers to use `.onion` addresses.
|
||||
- Created and joined anonymous chatrooms in incognito mode.
