title: Authenticate Rest API with Apache Shiro
body: <p>I have a Rest API backend (Rest based) which I want to secure now. I have looked into both Spring Security (for which I know implementation) and Apache Shiro. After learning that how shiro has a easy to use API, I want to implement it. However, there are no clear authorization tutorials to do this as I wanted to implement not just Basic Auth but Digest Authentication to have a more secured api. I have read that shiro has support for it. Also, I want to store my username and passwords in a databse and not in the ini file of shiro as shown in examples. Can anyone help me with this implementation? I have used Spring Rest for my apis.</p>
  
  <p>Any suitable tutorial will help.</p>
