In modern applications, security is paramount, especially when dealing with sensitive data. AES (Advanced Encryption Standard) is a widely used encryption algorithm for securing data. In this guide, we'll delve into implementing AES encryption and decryption in a Spring Boot application.

Setting Up the Project

Firstly, let's set up a basic Spring Boot project. You can use Spring Initializr or your preferred method to create a new Spring Boot project with the necessary dependencies.

Adding Dependencies
