title: Spring Security >5.0.0 removed Md5PasswordEncoder
body: <p>I have a Spring project using Spring security. I was using Spring Boot 1.5 and now I migrated to Spring Boot 2.0.</p>
  
  <p>I noticed that <a href="https://docs.spring.io/spring-security/site/docs/5.0.0.M5/api/org/springframework/security/authentication/encoding/Md5PasswordEncoder.html" rel="noreferrer">Md5PasswordEncoder</a> has been removed in the final release of Spring Security. Instead <code>Md4PasswordEncoder</code> is still present even if deprecated (<a href="https://docs.spring.io/spring-security/site/docs/5.0.3.RELEASE/api/" rel="noreferrer">https://docs.spring.io/spring-security/site/docs/5.0.3.RELEASE/api/</a>).</p>
  
  <p>Should I use extenal MD5 encoder or is the classed moved somewhere else?</p>
