Cryptography is essential in ensuring data security in today's digital world. It protects every action and message, ensuring information security.

What is Cryptography?

Cryptography is the art of securing information by transforming it into an incomprehensible format. Its primary goal is to allow only authorized individuals to access the data through encryption algorithms and keys. The main components include encryption, transforming plaintext into ciphertext, and decryption, restoring the original data.

Modern Types of Cryptography

Today, cryptography is divided into symmetric and asymmetric encryption. Symmetric encryption uses the same key for both encrypting and decrypting data, with examples like AES and DES. Asymmetric encryption uses a pair of keys: a public key for everyone and a private key for the owner. Examples include RSA and ECC, widely used in online banking and digital signatures.

Cryptography in Everyday Life

Cryptography permeates all aspects of our digital lives, securing social networks and smart devices. Without this technology, many modern systems would be vulnerable to security threats.

Cryptography is a fundamental component of security in the digital age, protecting critical data and maintaining user privacy.
