Modern web applications often expose sensitive data through APIs, making encryption a critical layer of defense. This article explores a hybrid encryption approach combining AES for speed and RSA for secure key exchange, implemented in a Vue.js frontend and Spring Boot backend. The pattern ensures that even if traffic is intercepted, the payload remains unreadable without the private key. Key considerations include key management, rotation strategies, and performance trade-offs. For developers building security-conscious applications, this architecture offers a robust starting point that can be adapted to various tech stacks.
