Here, cracking the code wasn’t just intellectual triumph. It was survival.
The Birth of Modern Cryptography
After World War II, cryptography entered a new era.
Computers replaced manual calculations. Mathematics became the backbone of encryption systems.
In 1977, a groundbreaking development changed everything: the introduction of public-key cryptography. Instead of relying on shared secret keys, this system used two keys — one public, one private.
The RSA algorithm, named after its creators, allowed secure communication over open networks.
This innovation laid the foundation for secure internet transactions, online banking, encrypted messaging, and digital signatures.
Without modern cryptography, e-commerce and global digital communication simply wouldn’t exist.
Secrets in the Digital Age
Today, encryption protects:
Financial transactions
Medical records
Government communications
Personal messages
Cloud storage
When you send a message through apps like WhatsApp or Signal, end-to-end encryption ensures that only you and the recipient can read the content.
Even companies themselves cannot easily access the messages.
But with greater encryption comes greater debate.
Privacy vs. Security: The Modern Dilemma
In the 21st century, codebreaking isn’t just about wartime espionage. It’s about privacy, law enforcement, and national security.
Governments argue that strong encryption can shield criminal activity. Privacy advocates counter that weakening encryption threatens civil liberties.
One high-profile example occurred in 2016, when the FBI requested that Apple Inc. unlock an iPhone belonging to a suspect. Apple resisted, arguing that creating a “backdoor” would compromise the security of all users.
