title: MD5 hash with different results
body: <p>Im trying to encode some chains to MD5 but I have noticed that:</p>
  
  <p>For the chain: "123456çñ"</p>
  
  <p>Some webs like </p>
  
  <p><a href="http://www.md5.net" rel="noreferrer">http://www.md5.net</a></p>
  
  <p>www.md5.cz</p>
  
  <p>md5generator.net</p>
  
  <p>return: "66f561bb6b68372213dd9768e55e1002"</p>
  
  <p>And others like:</p>

  <p>md5.rednoize.com/</p>
  
  <p>return: "9e6c9a1eeb5e00fbf4a2cd6519e0cfcb"</p>
  
  <p>I'd need to encode the chains with standar md5 because I need to connect my results with other systems. which hash is the correct?</p>
  
  <p>Thanks in advance</p>
