Tech has come a long way, and there’s always talk about what the next big thing might be. It’s worth taking a step back to appreciate the key moments that got us here in the first place.

Historical “Hacks”

Cybersecurity has been around longer than computers, if you really think about it. From physical locks to protecting personal information, the core idea of keeping things secure has been part of human history for thousands of years. “Cybersecurity” is just the modern branding.

One major turning point in this evolution was the use of cryptography. At its core, cryptography turns readable information into coded messages that can’t be understood by the average person. In today’s world, it’s a complex field powered by technology, but the concept is ancient.

One of the most historical turning points of how cryptography can be powerful was in 1943 during World War II.

About World War II

In 1939, Hitler invade Poland, triggering a chain reaction of geopolitical chaos. The Axis Powers, Germany, Italy, and Japan, went head-to-head with the Allied forces, which eventually included the U.S., U.K., Soviet Union, China, and others. World War II, which lasted from 1939 to 1945, was the most devastating and widespread conflict in human history, involving over 30 nations across Europe, Asia, Africa, and the Pacific. The war took a global turn when Japan attacked Pearl Harbor, bringing the United States into the conflict. The war ended in 1945 after Germany’s surrender in May and Japan’s surrender in August, following the atomic bombings of Hiroshima and Nagasaki by the United States.

Cryptography and World War II

Cryptography played a crucial role during World War II. This was to ensure diplomatic communications could not be intercepted and understood.

This led to investment of cryptoanalysts, also known as the “code-breaking experts.

On April 6, 1941, Germany attacked two countries, Yugoslavia and Greece. Germany sent in tanks, planes, and soldiers to take over the country. Which was all methodically planned through encrypted messaging.

Germany used a special machine called the Enigma machine, that scrambled the words into secret code so no one else could understand them.

Yet, the British had sent cryptoanalysts at a place called Bletchley Park, where they were instructed to spy and decode the secret German messages. On the day of the invasion, they were trying to figure out what Germany was planning, but they didn’t solve the code fast enough to warn the countries in time.

Meanwhile, the Germans had also figured out some of the messages from the other side (Yugoslavia and Greece), so they knew what their enemies were doing. This decrypted code assisted Germany win the battle quickly.

While soldiers were fighting on the ground, there was also a “spy battle” in the background with secret messages and codebreaking.

After Germany invaded Yugoslavia and Greece in April 1941, they quickly took control, but the invasion delayed their bigger plan to attack the Soviet Union. This caused German forces got stuck fighting in the freezing Russian winter, which weakened their army due to the harsh winter conditions.

Meanwhile, British cryptanalysts kept improving their skills in decoding German messages and eventually helped win important battles by decoding these messages. With Germany slowing down due to the winter conditions and the British decrypting messages faster, this helped the Allies win the war.

Cryptography Today

Major historic events like World War II show the importance of keeping private messages a secret.

This moment in history allowed the idea of encrypting and was implemented in today’s tech world. This includes phones, websites, or even digital keypads to a home.
