 \maketitle
+\section{Introduction}
+Cryptography is ubiquitous in our modern world.
+While the origins of cryptography date back thousands of years, evidence of its use in ancient is sparse.
+\cite{luenberger}
+Most of its use seemed to be reserved for political and military leaders, e.g. notably Mary Queen of Scots,
+who while in prison, plotted to kill Queen Elizabeth using encrypted letters \cite{enwiki:maryofscots}.
+With the widespread adoption of the internet, the need for several cryptographical functions arose.
+Due to its intended original use as a trusted research network (ARPANET),
+almost none of the original protocols were 'secure' in any sense of the word.
+Most notably still today is SMTP, the \textit{Simple Mail Transfer Protocol}, used to send email to servers.
+In its original implementation, it allowed attackers to intercept emails in transit to read and modify them
+and even spoof the sender address to impersonate others.
+SMTP today is secured using a combination of mitigations for these attacks, such as STARTTLS, SPF, DKIM and DMARC,
+emphasizing the need for securely designed protocols.
