please i want to know how sign and encryption without template file.
example code in c:\xmlsec-0.0.7\docs\examples\enc1 doesn't work well.
and that example code encrypt for memory data.
so i edit code and it sucessfully compile without error, but it does not work well.
follow code is reference in c:\xmlsec-0.0.7\apps\xmlsec.c and c:\xmlsec-0.0.7\docs\examples\enc1.
