Cryptography Protocols
Cryptography protocols are standardized sets of rules and procedures that use cryptographic techniques to secure communication, data exchange, and authentication over networks. They ensure confidentiality, integrity, and authenticity by employing encryption, digital signatures, and key management, often operating at various layers of network models like TLS/SSL for transport security or IPsec for network-layer protection.
Developers should learn cryptography protocols when building secure applications that handle sensitive data, such as financial transactions, healthcare records, or user authentication, to prevent eavesdropping, tampering, and unauthorized access. They are essential for implementing HTTPS in web apps, securing APIs, and ensuring compliance with regulations like GDPR or HIPAA, as they provide a foundation for trust in digital interactions.
