<h1>Anonymity - Easy Anonymous Chats Using SimpleX (and onion-only servers)</h1>
<img src="../closedsource/2.png" class="imgRz">
<p>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.</p>

<div class="col-lg-8 col-lg-offset-2">
<h2><b>Choosing the most appropriate chat application</b></h2>
<p>In order to choose the most appropriate messaging app for our intended use (Anonymity), we have the following requirements:</p>
<p><u>Privacy:</u></p>
<ol>
<li><p>The application must be free and open source (FOSS)</p></li>
<li><p>The application must have End to End Encryption by default (E2EE)</p></li>
<li><p>The application must allow us to run and use our own servers (Decentralisation)</p></li>
</ol>
<p><u>Anonymity:</u></p>
<ol>
<li><p>The application must support Tor .onion servers out of the box</p></li>
<li><p>The application must allow you to chat without requiring any information (no emails, no usernames, no phone numbers)</p></li>
<li><p>The application must have the ability for us to join chatrooms without revealing our identity (Incognito Mode)</p></li>
</ol>
<p><u>Deniability:</u></p>
<ol>
<li><p>The application must have disappearing messages (Deniability)</p></li>
</ol>
<p>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.</p>

<div id="anon2">
<div class="container">
<div class="row">
<div class="col-lg-8 col-lg-offset-2">
<h2><b>How to Set Up Anonymous Chats</b></h2>
<h3><b>Step 1. Option A: GNU/Linux</b></h3>
<p>First, update your package list and install Tor by running the following commands in your terminal:</p>
<pre><code class=nim">sudo apt update
sudo apt install tor</pre></code>
<p>Once installed, start the Tor service:</p>
<pre><code class=nim">sudo systemctl start tor@default</pre></code>
<p>Next you'll need to download SimpleX AppImage which can be <a href="https://simplex.chat/downloads/">found here on SimpleX website</a>.</p>
<p>Open a terminal in the directory of your downloaded AppImage. Make the AppImage executable, then launch it:</p>
<pre><code class=nim">
[ mainpc ] [ /dev/pts/26 ] [~]
→ chmod +x simplex-desktop-x86_64.AppImage
[ mainpc ] [ /dev/pts/26 ] [~]
→ ./simplex-desktop-x86_64.AppImage
</pre></code>
<h3><b>Step 1. Option B: Android</b></h3>
<p>Download and install the Orbot .apk from <a
href="https://github.com/guardianproject/orbot/releases"
target="_blank">the GitHub repository</a>.</p>
<img src="Orbot1.png" class="imgRz"
alt="Orbot installation screenshot">
<p>Open Orbot, and in the bottom-right corner, tap on <strong>More</strong>, then <strong>Settings</strong> to enter the settings.</p>
<p>In the settings menu, scroll down and enable the <strong>Power User Mode</strong>.</p>
<p>After enabling Power User Mode, go back to the More section and press <strong>Choose apps</strong> and select SimpleX in the list. Go back to <strong>Connect</strong> in the bottom navigation menu and press <strong>Connect</strong>.</p>
<!--<img src="Orbot2.png" class="imgRz" alt="Orbot PUM screenshot">-->
<img src="orbot.png" class="imgRz">
<p>Download and install <a
href="https://f-droid.org/packages/chat.simplex.app/">SimpleX
using F-Droid</a></p>
<img src="Simplex1.png" class="imgRz"
alt="SimpleX installation screenshot">
<h3><b>Step 2.</b></h3>
<p>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.</p>
<img src="Simplex2.png" class="imgRz" alt="SimpleX setup screen">
<p>Once you've created your profile, open the kebab menu on the
bottom left and open <strong>Settings &gt; Network and servers</strong>
and activate SOCKS Proxy. Press <strong>SOCKS proxy settings</strong> and set your
port to 9050, then save.</p>

<!-- SimpleX Server Setup -->
<div id="anon3">
<div class="container">
<div class="row">
<div class="col-lg-8 col-lg-offset-2">
<h2><b>Step 3. SimpleX Server Setup</b></h2>
<p>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.</p>
<p>We're going to make use of <a href="https://forum.hackliberty.org/t/simplex-server-docker-installation-guide-smp-xftp/140">HackLiberty's tutorial</a> on how to install and configure a
SimpleX server using Docker.</p>
<p>First we're going to create the docker-compose.yml file and the .env file as follows:</p>
<pre><code class="nim">
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ cat docker-compose.yml

</pre></code>
<p>Then we're going to create the folders as follows:</p>
<pre><code class="nim">
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ mkdir -p {xftp,smp}/{config,logs}
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]

[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ mkdir -p {xftp,smp}/{config,logs}
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ chmod 700 tor-data/simplex-xftp
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ chmod 700 tor-data/simplex-smp
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]

[ 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
</pre></code>
<p>Be aware that <a href="">SimpleX's documentation</a> 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:</p>
<pre><code class="nim">
SOCKSPort 0
HiddenServiceNonAnonymousMode 1
HiddenServiceSingleHopMode 1
</pre></code>
<p><b>DO NOT USE THESE, otherwise your servers' location will be known. You need to use the following instead:</b></p>
<pre><code class="nim">
[ 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
</pre></code>
<p>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:</p>
<pre><code class="nim">
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ docker-compose up
[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]

[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]

[ Wonderland ] [ /dev/pts/15 ] [/srv/simplex]

[ 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
</pre></code>
<p>Then we'll save both the private keys in our keepass and then shred them:</p>
<pre><code class="nim">
#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
</pre></code>
<p>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.</p>
<pre><code class="nim">
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ cat smp/config/smp-server.ini | tail -n3

# You can specify multiple server ports.
host: nowhere
#port: 5223,443 ## we dont need 443!
port: 5223
log_tls_errors: off
</pre></code>
<p>Then we also configure it so that the simplex smp server goes through the docker tor daemon to connect to other servers:</p>
<pre><code class="nim">
[ 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]

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)

# 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
[ Wonderland ] [ /dev/pts/14 ] [/srv/simplex]
→ cat xftp/config/file-server.ini
[STORE_LOG]
# The server uses STM memory for persistence,
# that will be lost on restart (e.g., as with redis).
# This option enables saving memory to append only log,
# and restoring it when the server is started.
# Log is compacted on start (deleted objects are removed).

log_stats: off
[AUTH]
# Set new_files option to off to completely prohibit uploading new files.
# This can be useful when you want to decommission the server, but still allow downloading the existing files.
new_files: on
# Use create_password option to enable basic auth to upload new files.
# The password should be used as part of server address in client configuration:

</pre></code>
<p>Then we simply run the docker containers again:</p>
<pre><code class="nim">

</pre></code>
<p><u>Sidenote:</u> 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 <a href="http://nowherejezfoltodf4jiyl6r56jnzintap5vyjlia7fkirfsnfizflqd.onion/simplex.html">here</a>: </p>
<img src="36.png" class="imgRz">
<p>Or you can list your simplex servers on public lists like this one:</p>
<img src="37.png" class="imgRz">
<p>Once that's done, we can go ahead and add the servers in our simplex client:</p>

<p>And now that our simplex client is ONLY using our onion-only simplex servers, we can create our own chatrooms:</p>

<img src="29.png" class="imgRz">

<p>Enter a name for your group. You can also add a photo for the

allows for anonymous connections with other people without shared
data. Once you have filled out the necessary information, press
<strong>Create group</strong>.</p>
<img src="31.png" class="imgRz">
<p>as noted above, since you are only using tor-only simplex servers, <b>this means that you are forcing the users to use Tor to be able to join your invite links.</b> Here's what the invite link looks like:</p>
<pre><code class="nim">
https://simplex.chat/contact#/?v=2-7&smp=smp%3A%2F%2FBD4qkVq8lJUgjHt0kUaxeQBYsKaxDejeecxm6-2vOwI%3D%40<b>b6geeakpwskovltbesvy3b6ah3ewxfmnhnshojndmpp7wcv2df7bnead.onion</b>%2FSMvbQfvtczzC7r6Sv3gEgy_s01_ZYPh_%23%2F%3Fv%3D1-3%26dh%3DMCowBQYDK2VuAyEA9kSAhfaJMzC8YWZzkpoCL8mnBmq2U8VE8_v5HYk0nyE%253D&data=%7B%22groupLinkId%22%3A%22zjrwnXSNIBJO9ZhoHcRRkQ%3D%3D%22%7D
</pre></code>
<p>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 <b>https://simplex.chat/</b> at the beginning with your simplex smp server onion url as follows:</p>

<p>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 <b>simplex:/</b>, which will transform the link as follows:</p>

<h2><b>How to Join Chatrooms in Incognito mode</b></h2>
<p>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 <strong>Search or paste SimpleX link</strong>.</p>
<p>Paste your invite link into the input field and press <strong>Enter</strong>.</p>
<img src="32.png" class="imgRz">
<p>You will be met with a window asking whether you'd like to
connect using your current profile or using an Incognito profile.</p>
<p>Select <strong>Use new incognito profile</strong>. </p>
<p>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.</p>
<img src="33.png" class="imgRz">
<p>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.</p>
