[xmlsec] example 1 always give the same digest value

[Derek Lei Liu]

Hi,

I am trying to use example1 on Solaris. The test xml
and the private key are attached in following.  I
tried to use local reference here, but found the
digested value never changed even I changed the
content in <Data>.  I am relatively new to this area
and the project I am working on is rather urgent on
this part.  I gdb into the test program and found that
the first time SHA1_Update was called as for
<SignInfo> (signature stuff).  This function is
supposed to be called for the digested value, right?

thanks

Derek
