Among them was Alan Turing, whose contributions to breaking Enigma are widely regarded as pivotal to the Allied victory.
Historians estimate that successful codebreaking shortened the war in Europe by up to two years — saving millions of lives.
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.
