title: is it normal to have different md5 for apache maven
body: <p>I am downloading apache marven form this official website</p>
  
  <p><a href="https://maven.apache.org/download.cgi" rel="nofollow">https://maven.apache.org/download.cgi</a></p>
  
  <p>I downloaded    <code>apache-maven-3.3.3-bin.tar.gz</code> and calculated the md5 and the result is  <code>9f0fa573a526785b8e0adb0631687ad5</code> while the result on the official page is: <code>794b3b7961200c542a7292682d21ba36</code></p>
  
  <p>** is that normal? **</p>
  
  <p>then i downloaded apache-maven-3.3.3-bin.zip and for some reason, my mac 10.10.1 gives me a folder after finishing downloading not a zip file</p>
  
  <p>i am worried about the security of that file since there are two different md5 results, is that normal please?</p>
