title: Spring Config Server encrypting issue of "=" sign
body: <p>Can anyone experience problem while encrypting through config server with values having special characters?</p>
  
  <p>Currently I am doing this </p>
  
  <pre><code>curl http://localhost:8888/configser/config/encrypt -d eF345edo=
  </code></pre>
  
  <p>I also referred this <a href="https://github.com/spring-cloud/spring-cloud-config/issues/620" rel="noreferrer">https://github.com/spring-cloud/spring-cloud-config/issues/620</a> and tried as below</p>
  
  <pre><code>curl http://localhost:8888/configser/config/encrypt --data-urlencode eF345edo=
  </code></pre>
  
  <p>But still no success in encrypting that <strong>'='</strong> sign.</p>
  
  <p>Thanks in advance</p>
