Both includes some common imported code, for example the AES implementation. </div> 44<hr size="1"><address style="text-align: right;"><small> 45Generated on Wed Jan 11 14:07:38 2012 for Heimdal crypto library by <a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.5.6</small></address> 46</body> 47</html> 48
