Abstract
Cryptography is the science and practice of securing communication and data through the use of mathematical techniques. It involves the design and analysis of protocols that prevent unauthorized access to sensitive information. Cryptography plays a vital role in ensuring confidentiality, data integrity, authentication, and non-repudiation in digital communications. Key concepts within cryptography include symmetric and asymmetric encryption, cryptographic hash functions, digital signatures, and public key infrastructure (PKI). Asymmetric encryption, which relies on key pairs (public and private keys), enables secure communication over open channels, such as the internet, while symmetric encryption is often used for efficient data encryption in closed systems. Cryptographic methods are foundational to modern technologies, including secure web.
