title: terminal version of mcrypt
body: <p>I'm trying to use the terminal version of mcrypt but I haven't success...</p>
  
  <p>I writed:
  <code>mcrypt -a xtea -m ecb -k "qawsedrftgyhujik" test &gt; testresult</code></p>
  
  <p>where:</p>
  
  <ul>
  <li>xtea is the algorithm</li>
  <li>ecb is the mode</li>
  <li>qawsedrftgyhujik is the 128bits key</li>
  <li>test is the source file</li>
  <li>testresult is the target file</li>
  </ul>
  
  <p>The program gets freeze and I have to abort with ctl+c. Does anyone knows why?</p>
