title: How to create a normal password-protected ZIP archive?
body: <p>My app zips several files, saves the zip file to the SD card, and it emails the zip file to an address.</p>
  
  <p>The zipping is done with this code: <a href="http://www.jondev.net/articles/Zipping_Files_with_Android_%28Programmatically%29" rel="noreferrer">Zipping Files with Android (Programmatically)</a>.</p>
  
  <p>Now the question is, how do I put a password on the zip file so that authorized individuals who opens it on a computer (Windows, Mac, or Ubuntu) would be able to extract the files with a supplied password?</p>
  
  <p>I read this post: <a href="https://stackoverflow.com/questions/4162711/android-zip-file-authentication">Android zip file authentication</a>, but it sounds to me that reading of the zip is done with another phone... or am I wrong? 
  If anybody knows please let me know! Thanks!</p>
