[xmlsec] Signing an XML file.

[Jean Cyr]

Forgive my ignorance but I am new to this and I need a little help to get me started. My objective is to sign an arbitrary XML file
using an openssl generated private key and certificate.

The XML file (4uonly.xml):

<?xml version="1.0" ?>
<XML_DIZ_INFO>
	<Company_Info>
		<Company_Name>Dillobits Software, Inc.</Company_Name>
	</Company_Info>
</XML_DIZ_INFO>

The private key (Dillo.key):

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,8F9F5B674A6E8E74

u+t1otoa0+f6C5oDR12TyLHLSpIsfFIMXDBdIkAdZQtEW4K819YEaJb3cpqB/6qR

GZt3sFmZlc0USDf91hnH4Y26cZFjuB0wi+esG1J3Kqg=
-----END RSA PRIVATE KEY-----

The certificate (Dillo.crt):

-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----

When I issue the following command:

xmlsec --sign-tmpl --pubkey-cert-pem Dillo.crt --privkey-pem Dillo.key 4uonly.xml

I get:

Enter password for "Dillo.key" file:
func=xmlSecKeysMngrGetKey:file=..\src\keys.c:line=1364:obj=unknown:subj=xmlSecKeysMngrFindKey:error=1:xmlsec library function

I'm obviously mssing something, but what?
