title: About Spring Boot encrypt/decrypt functions
body: <p>I'm looking for some advice about Spring boot CLI command <a href="https://cloud.spring.io/spring-cloud-config/reference/html/#_security" rel="nofollow noreferrer">encrypt/decrypt</a>:</p>
  <p>I understand that Java Cryptography Extension is required for those functions.
  They provide symmetric encryption.</p>
  <p>Does anyone know what kind of algorithm is used?
  Is it possible to configure this?</p>
