\section{Use Secure Messaging}\label{use-secure-messaging}
|
||
|
|
||
|
Posted on: \textbf{23 January 2024}
|
||
|
|
||
|
Category: \textbf{Software} \& \textbf{Technology}
|
||
|
|
||
|
In an era of uncomfortably intrusive tracking, the requirement for
|
||
|
secure messaging has become crucial. With companies like
|
||
|
\href{https://www.eff.org/deeplinks/2018/03/one-answer-facebook-problem-block-its-tracking-technologies}{Meta}
|
||
|
and
|
||
|
\href{https://www.eff.org/deeplinks/2020/03/google-says-it-doesnt-sell-your-data-heres-how-company-shares-monetizes-and}{Google}
|
||
|
intruding our privacy on a daily basis, we must take a stand, especially
|
||
|
with the messaging applications, perhaps the most sensitive piece of
|
||
|
software that people use. In this article, I will explain why it is
|
||
|
urgent for you to take the stand by using secure messaging and explain
|
||
|
how to get started.
|
||
|
|
||
|
\hypertarget{privacy-an-ignored-factor}{%
|
||
|
\subsection{Privacy: An Ignored
|
||
|
Factor}\label{privacy-an-ignored-factor}}
|
||
|
|
||
|
Privacy is incredibly important in this modern day and age. This is why
|
||
|
I will only speak about messaging software that is \textbf{both private
|
||
|
and secure.} When choosing software, privacy and security should have
|
||
|
equal importance.
|
||
|
|
||
|
\hypertarget{why-}{%
|
||
|
\subsection{Why?}\label{why-}}
|
||
|
|
||
|
Why would one use secure messaging if they have nothing to hide?
|
||
|
|
||
|
\hypertarget{protecting-your-privacy}{%
|
||
|
\subsubsection{Protecting Your Privacy}\label{protecting-your-privacy}}
|
||
|
|
||
|
Your privacy is incredibly important. However, it is ignored by most
|
||
|
people, citing that they have nothing to hide. Everyone has something to
|
||
|
hide, whether that be related to their money, reputation or even
|
||
|
personal issues. Imagine your reaction if your current messages in their
|
||
|
entirety got leaked, allowing anyone to read and go through them. You
|
||
|
would be uncomfortable and also fear people taking advantage of your
|
||
|
private messages. It is for this reason that it is important to
|
||
|
safeguard your most personal conversations.
|
||
|
|
||
|
\hypertarget{avoiding-cyber-threats}{%
|
||
|
\subsubsection{Avoiding Cyber Threats}\label{avoiding-cyber-threats}}
|
||
|
|
||
|
Secure messaging uses end-to-end encryption. However, it is not wise to
|
||
|
completely trust when companies advertise end-to-end encryption. It
|
||
|
depends mostly on the algorithm that they use. For example, the Signal
|
||
|
protocol is open-source and fully available to the public. This allows
|
||
|
people to view and even contribute to improving its overall
|
||
|
effectiveness. However, WhatsApp\textquotesingle s encryption is
|
||
|
proprietary. No one knows what encryption algorithm WhatsApp is running
|
||
|
on their servers which makes it impossible to determine if it is secure.
|
||
|
All in all, you should do your own research before proceeding.
|
||
|
|
||
|
\hypertarget{protecting-metadata}{%
|
||
|
\subsubsection{Protecting Metadata}\label{protecting-metadata}}
|
||
|
|
||
|
Your \href{https://ssd.eff.org/module/why-metadata-matters}{metadata is
|
||
|
crucial} to protecting your conversations. It can give context to your
|
||
|
messages. Protecting your metadata helps mask your messages and protects
|
||
|
it from being tampered.
|
||
|
|
||
|
\hypertarget{getting-started}{%
|
||
|
\subsection{Getting Started}\label{getting-started}}
|
||
|
|
||
|
I will be showcasing how to download and use secure messaging apps. As
|
||
|
aforementioned, I will only show apps that are \textbf{both secure and
|
||
|
private.}
|
||
|
|
||
|
\hypertarget{1-choose-a-secure-app}{%
|
||
|
\subsubsection{1. Choose a secure app}\label{1-choose-a-secure-app}}
|
||
|
|
||
|
Firstly, download one of the following:
|
||
|
|
||
|
\begin{enumerate}
|
||
|
\tightlist
|
||
|
\item
|
||
|
\href{https://www.signal.org/}{Signal} - It is free, open-source and
|
||
|
is a great alternative for WhatsApp
|
||
|
\item
|
||
|
\href{https://getsession.org/}{Session} - It is incredibly private.
|
||
|
You do not get a phone number and have to backup a seed phrase, making
|
||
|
it complicated for most users.
|
||
|
\item
|
||
|
\href{https://threema.ch/en}{Threema} - Threema is a \textbf{paid}
|
||
|
option but also easy to use.
|
||
|
\end{enumerate}
|
||
|
|
||
|
Next, open your app and set it up. Keep only the bare minimum data about
|
||
|
you. For my name, I keep a dash (-) and no profile picture.
|
||
|
|
||
|
\hypertarget{2-enable-two-factor-authentication}{%
|
||
|
\subsubsection{2. Enable two-factor
|
||
|
authentication}\label{2-enable-two-factor-authentication}}
|
||
|
|
||
|
Now, enable \href{https://sufyaan.me/tfa}{two-factor authentication} if
|
||
|
available. This allows you to prevent others from registering using your
|
||
|
credentials without your consent.
|
||
|
|
||
|
\hypertarget{3-keep-updating}{%
|
||
|
\subsubsection{3. Keep updating}\label{3-keep-updating}}
|
||
|
|
||
|
Regularly check for updates. If an app has an update, update it. This
|
||
|
prevents security and privacy breaches from occurring.
|
||
|
|
||
|
\hypertarget{4-use-disappearing-messages}{%
|
||
|
\subsubsection{4. Use disappearing
|
||
|
messages}\label{4-use-disappearing-messages}}
|
||
|
|
||
|
Keep disappearing messages on by default. This ensures that sensitive
|
||
|
messages are deleted within a period of time. For extremely sensitive
|
||
|
chats, consider visiting the person you want to talk to physically. If
|
||
|
that is not an option, turn on disappearing messages and set a time
|
||
|
limit for 5 minutes and chat with them, so that the messages disappear
|
||
|
after 5 minutes.
|
||
|
|
||
|
\hypertarget{5-educate-your-contacts}{%
|
||
|
\subsubsection{5. Educate your contacts}\label{5-educate-your-contacts}}
|
||
|
|
||
|
If your contacts are still on other messaging apps, convince them to
|
||
|
join secure messaging apps as well. This allows you to have a secure
|
||
|
option even if your main chats are on the other app.
|
||
|
|
||
|
\hypertarget{conclusion}{%
|
||
|
\subsection{Conclusion}\label{conclusion}}
|
||
|
|
||
|
In conclusion, it is important to employ secure messaging. Signal,
|
||
|
Session and Threema are all viable applications that one can use. If
|
||
|
only a few of your contacts are on Signal, do not worry. Talk to them on
|
||
|
Signal and the others on the app you talk with them on. Remember,
|
||
|
privacy is a journey, not a destination.
