Abstract 
In the digital age, network security has become the key to protect information security. As the cornerstone of network security, cryptography is becoming more and more important in the design of security products. This paper discusses the design and application of cryptography in network security products. This paper first introduces the basic concept of cryptography and its role in ensuring data security in network communication, and then analyzes the application of cryptography techniques such as symmetric encryption, asymmetric encryption, hash function and digital signature in security products. The paper also discusses the specific application scenarios of cryptography in the design of network security products, such as VPN, SSL/TLS protocol, firewall and intrusion detection system, and emphasizes the important functions of cryptography in protecting the confidentiality, integrity and authentication of data transmission and storage. At the same time, this study points out the challenges facing the application of cryptography in current network security products, including the potential threats of quantum computing, the selection and updating of encryption algorithms, and the complexity of key management and distribution. This paper summarizes the role of cryptography technology in improving the performance of network security products, and foresees the future development trend of cryptography, such as the application prospect of post-quantum cryptography and the utilization of artificial intelligence and machine learning technology in password attack and defense. This research focuses on the design and application of cryptography in network security products. Cryptography is the key technology of information security, which provides data confidentiality, integrity and authentication mechanism.
