title: Decrypt hashed password
body: <p>For a lecture I have to decrypt a hash...but in the exercise no hint was given at all.</p>
  
  <p>The only information that was supplied is this:</p>
  
  <pre><code>user;pass
  leroy;06e2b745f3124f7d670f78eabaa94809
  </code></pre>
  
  <p>I should decrypt the passphrase and describe how such a task is done but unfortunately I have no idea how to approach this problem.</p>
  
  <p>My first ideas where that it is "leroy" or "jenkins" (or something like "jenkinS") in md5 or something so I simply tried to guess the passphrase but I had no luck.</p>
  
  <p>Could you give me a hint on how to approch such a problem?</p>
