Cryptography and security are crucial fields where C and C++ programming languages play a significant role. These languages are commonly utilized due to their low-level access, strong control over memory, and ability to manipulate data efficiently.

• C is often employed in cryptography and security applications because of its direct manipulation of data and memory. It enables developers to implement cryptographic algorithms, encryption protocols, and secure communication systems;
• C++ builds upon C and provides additional features such as classes and object-oriented programming, allowing for the development of more complex and secure software systems.

In cryptography, C and C++ facilitate the implementation of algorithms like AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and SHA (Secure Hash Algorithms). These languages provide the necessary tools for secure key management, secure random number generation, and data integrity verification.

Security-focused applications, such as secure file transfer protocols, secure messaging systems, and network security tools, heavily rely on C and C++.
