I haven't used command line parameters, but signature template file in XML.

Then there is probably another problem. My files were in UTF-8 with
proper <?xml version="1.0" encoding="utf-8"?> declaration. But xmlsec
was unable to find matching key (last error msg=Cannot find object or
property). I even tried to escape Czech characters using &#...;
notation, but without success.

I'm not familiar with xmlsec internals, but I suppose that it uses
libxml2 for parsing, so input encoding should be converted to UTF-8 for
in-memory storage. So encoding of XML file shouldn't matter?

Unfortunatelly, it was *not working*.

Still no success, but many thanks for help.
