Overview

Cryptography is the study and practice of techniques for secure communication, ensuring that information remains confidential and protected from unauthorized access. It involves the use of algorithms, protocols, and cryptographic primitives to encrypt, decrypt, and authenticate data.

Key Facts

• Cryptography dates back to ancient civilizations, with evidence of encrypted messages found in Egyptian and Greek texts.

The concept of cryptography has evolved over time, from Caesar ciphers to modern cryptographic protocols like SSL/TLS. Cryptography plays a crucial role in securing online transactions, communication networks, and data storage systems.
