<P>Please I want to know how sign and encryption without template file.</P>
<P>Example code in C:\xmlsec-0.0.7\docs\examples\enc1 doesn't work well. </P>
<P>And that example code encrypt for memory data. </P>
<P>so I edit code and it sucessfully compile without error, but it does not work well.</P>
<P>Follow code is reference in C:\xmlsec-0.0.7\apps\xmlsec.c and C:\xmlsec-0.0.7\docs\examples\enc1.</P>
