Encryption
Encryption is the process of converting plaintext data into a secure code, known as ciphertext, using algorithms and keys to prevent unauthorized access. In modern contexts, it's essential for safeguarding digital communications, from protecting online banking to shielding personal emails from cyber threats, making it a cornerstone of privacy in an increasingly connected world.
Did you know?
The Enigma machine, used by the Germans in World War II, employed encryption so complex that it took Allied codebreakers like Alan Turing years to crack, ultimately shortening the war. Today, over 90% of internet traffic is encrypted, thanks to protocols like HTTPS, which has dramatically reduced data breaches since its widespread adoption in the 2010s.
