title: MD5 hash decryption when knowing part of input
body: <p>Is it possible to decrypt an MD5 hash if you have part of the original text? Like:</p>
  
  <pre><code>Text     : hi how are you?
  MD5 hash : 31a015d54f92382d2cee35eb2f0cc556
  </code></pre>
  
  <p>MD5 hashes can't be decrypted, but if I know part of the text like <code>hi how are</code>, does that help?</p>
