Fwd: Re: [xmlsec] Problems with MScryto.

[Francisco Lechón]

Hola Wouter,

Thank you very much by the aid that you have contributed to me.
Now, I have a problem.  As I can add to the signature the node that contains 
the information of the public key?
...
<KeyValue><RSAKeyValue>
<Modulus>zUhfl2qzFXgfy....BtkEGknBs=</Modulus>
<Exponent>AQAB</Exponent>
</RSAKeyValue></KeyValue>
...
When attempt to add it to a signature, is empty:
...
<KeyValue><RSAKeyValue>
<Modulus/><Exponent/>
</RSAKeyValue></KeyValue>
...

Following the code, I arrive at a point where it says to me that the key is 
private.
...
int xmlSecKeyReqMatchKey(xmlSecKeyReqPtr keyReq, xmlSecKeyPtr key) {
    xmlSecAssert2(keyReq != NULL, -1);
    xmlSecAssert2(xmlSecKeyIsValid(key), -1);
    if((keyReq->keyType != xmlSecKeyDataTypeUnknown) &&
      ((xmlSecKeyGetType(key) & keyReq->keyType) == 0)) {
--->	 return(0);
    }
...

Is necessary to initialize some field to be able to add to the node < 
KeyValue >?

Thanks,
Paco
