[xmlsec] How to get Certificate from signed xml file

Hi,

How I can get the certificate from a signed xml file and save this vertificate 
as a file on my local machine?

Thanks for any help

If you are writing a program in C then you have access to
the signature certificates through xmlSecDsigCtx data
structure. Check the documentation for more details.

You can get to signature key, from key you can get access
to "KeyData" objects. Then you need to iterate through
the list and find one for certificate (note, this part
is crypto specific!). Then you can get a handle no native
"crypto" certificate (e.g. for OpenSSL it will be X509*).

get access to the certificate itself or to save the certificate ;o(

Well i find my certificate, but how to export now?


I believe you found the key, not certificate. Look at
KeyData objects in this key.

Hi Aleksey,

Well now I got my Certificate from signed xml ;o)
Using the following code.

key = dsigCtx.signKey;
size = xmlSecPtrListGetSize(key->dataList);
sdata = (*((dsigCtx).signKey)).dataList;
for(pos = 0; pos < size; ++pos) 
{
tmp = (xmlSecKeyDataPtr)xmlSecPtrListGetItem(key->dataList, 
pos);
if((tmp != NULL) && (tmp->id == sdata->id)) 
return(xmlSecPtrListSet(key->dataList, data, pos));
} 

But I still don't find a way the export this certificate to my local machine 
for example c:\mycert.cer.

Thanks for any help

Thank Aleksey.

This is my code.


key = dsigCtx.signKey;
size = xmlSecPtrListGetSize(key->dataList);
sdata = (*((dsigCtx).signKey)).dataList;
for(pos = 0; pos < size; ++pos) 
{
tmp = (xmlSecKeyDataPtr)xmlSecPtrListGetItem(key->dataList, 
pos);
if(tmp != NULL) 
   xmlSecPtrListSet(key->dataList, data, pos);
}

x509 = xmlSecOpenSSLKeyDataX509GetCert(tmp, pos); 

But x509 is alwys 0x00. Any ideas why this can be?

Thanks
Jürgen

So, Now I got my certificate. I was using the 
xmlSecMSCryptoKeyDataX509GetCert Function.
The X509 Struct is filled, but how can I write this info now to my local 
disk into one cert file?
