I've got an XML file which should be signed with certificate enerated from openSSL. 

```

Whe i try to check if it is well signed one software say that everything is ok(<http://www.pemi.org.pl/index.php/do-pobrania/31-aplikacja-protektor>), and when i try to verify it in other it's says that signature is not valid(<http://sigillum.pl/pliki_do_pobrania.html>). Can someone verify the signature? Or maybe say me how to get 100% certainty.
