What is Jasypt?

Jasypt (Java Simplified Encryption), provides encryption support for property sources in Spring Boot Applications. It will help you to add basic encryption features to your projects with very fewer effort and without writing any code with the help of a few additions in your project here and there. Springboot is a very powerful framework that will help you add encryption capability without implementing any cryptography method. Jasypt is highly configurable.

In this article, we will learn how to encrypt data in Spring Boot application config files like application.properties or application.yml. Inside those files, we can encrypt username, password, etc.

You often come across developing projects where you have to connect to databases like MongoDB, etc, and store the authentic password of the DB connection in the config file of the spring boot project (application.yml or application.properties). Even passwords or tokens required for Authorization to make other API calls are also stored in the same way. You can actually refrain from adding the actual password in the config file and use jasypt-spring-boot a Java library.
