Applied Cryptography: Protocols, Algorithms and Source Code in C

Applied Cryptography is a field that focuses on the application of cryptographic techniques in systems and communications to ensure data security and privacy. It involves using protocols and algorithms to protect sensitive information from interception and cyber attacks. Additionally, cryptography is used to authenticate the identity of the parties involved in communication, ensuring the integrity of exchanged data.

In this context, the C programming language is widely used to implement cryptographic algorithms due to its efficiency and versatility. Through C source code, it is possible to develop robust and secure systems that ensure the confidentiality and authenticity of transmitted information. Moreover, there are libraries and frameworks in C that facilitate the implementation of cryptographic protocols, making the data protection process simpler and more effective.

In summary, Applied Cryptography encompasses the use of protocols, algorithms, and C source code to ensure information security in systems and communications. Through cryptographic techniques, it is possible to protect sensitive data, authenticate transactions, and ensure the integrity of exchanged information. The C programming language stands out as an efficient option for implementing cryptographic algorithms, enabling the development of robust and secure systems. Description by ChatGPT.
