Make sure that you actually have *both* private key and certificate in the usercert.p12

Hi

We are trying to sign an XMl document with an X509 certificate, but any having problems getting the X509Data node populated.

We are following Philippe Camacho's tutorial here:
http://www.dcc.uchile.cl/~pcamacho/tutorial/web/xmlsec/xmlsec.html#htoc7 <http://www.dcc.uchile.cl/%7Epcamacho/tutorial/web/xmlsec/xmlsec.html#htoc7>

The command that we use is copied from the tutorial, and we are using the keysncerts.zip file that contains the appropriate keys and certificates.

The command (using v 1.2.16 on Mac OSX 10.6) is:
xmlsec1 --sign --pkcs12 usercert.p12 --trusted-pem cacert.pem --pwd hello doc-x509.xml

The contents of the doc-x509.xml is (the document we are trying to sign):

We get this output from running the command:

As you can see, the X509Data node is blank.

We have tried including the --print-xml-debug option, and this shows a number of fields, including:

<X509Data>
<KeyCertificate>
<SubjectName>/C=CL/ST=RM/O=littlecryptographer/CN=John Smith/[email protected] <mailto:[email protected]></SubjectName> <IssuerName>/C=CL/ST=RM/L=Santiago/O=littlecryptographer/CN=Philippe Camacho/[email protected] <mailto:[email protected]></IssuerName>
<SerialNumber>11E</SerialNumber>
</KeyCertificate>
</X509Data>

We have also tried these commands with our own generated keys, and different XML files too. We get the same result each time.

I have searched this mailing list, and note that Braja Biswal had a similar problem:
http://www.aleksey.com/pipermail/xmlsec/2009/008672.html

We would really appreciate any help, as we seem to be out of ideas. Our last idea is to try the same approach using Ubuntu - perhaps this is "a Mac thing". We used MacPorts to install Xmlsec.

Thanks

Nigel
