Cryptography: The Backbone of Digital Security in the Modern World
Cryptography: The Backbone of Digital Security in the Modern World In the vast and interconnected world of the internet, data is the most valuable asset. From banking transactions to private messages, sensitive information constantly travels across networks, making it a prime target for cybercriminals. Cryptography is the art and science that keeps this information safe — ensuring privacy, authenticity, and integrity. What is Cryptography? Cryptography is the practice of securing communication and data through the use of mathematical algorithms. It converts readable data ( plaintext ) into unreadable form ( ciphertext ) so that only authorized parties can decode it. There are two main types of cryptography: Symmetric Key Cryptography – Uses the same key for encryption and decryption. Asymmetric Key Cryptography – Uses a public key for encryption and a private key for decryption. Why is Cryptography Important? Data Privacy – Prevents unauthorized access to sens...
