    jasypt-spring-boot

    jasypt-spring-boot

    Jasypt integration for Spring boot

    Jasypt Spring Boot provides Encryption support for property sources in Spring Boot Applications. There are 3 ways to integrate just-spring-boot in your project. And encryptable properties will be enabled across the entire Spring Environment (This means any system property, environment property, command line argument, application.properties, yaml properties, and any other custom property sources can contain encrypted properties) Jasypt uses an StringEncryptor to decrypt properties. For all 3 methods, if no custom StringEncryptor (see the Custom Encryptor section for details) is found in the Spring Context, one is created automatically that can be configured through the following properties (System, properties file, command line arguments, environment variable, etc.).
