title: java.* package for encoding decoding
body: <p>I have used <code>com.sun.org.apache.xerces.internal.impl.dv.util.Base64</code> package for the purpose of  encoding decoding of strings. But I want to use <code>java.*</code> package for encoding and decoding instead of <code>com.sun.apache.*</code> package. </p>
  
  <p>Can you please suggest an appropriate <code>java.*</code> package?</p>
