All certificates from KeyInfo not considered in path building process #76

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Try to validate a document containing intermediate certificates in the 
KeyInfo but with each certificate in a separate X509Data.

What is the expected output? What do you see instead?
All certificates from KeyInfo are expected to be considered in the path 
building process. However, the path building fails as only the certificate(s) 
from the first X509Data are considered.

What version of the product are you using?
1.3.0

The attached patch fixes the issue by including all certificates found also 
from the other X509Data (if any).

XML-DSIG has some rules about this: 
http://www.w3.org/TR/xmldsig-core/#sec-X509Data.

It states that X509Data elements should only contain certificates that are part 
of the chain.

Also it states that if multiple X509Certificate are present within the same 
X509Data element, at least one of them should refer to the validation key.

do you think there's value on enforcing these rules? I don't know if Apache 
Santuario is checking this (or the other rules on the link above).

Probably it's better to just collect all the certificates, no matter their 
organization, as suggested on your patch.

I don't think being a little bit more relaxed than the XML-DSIG specification 
in this aspect would be a problem. There could be documents with totally 
unrelated certificates included but that shouldn't cause any issues.

Agreed. I'll apply the patch when possible. Tks!

I ended up also searching for IssuerSerial and SubjectName on all the 
ds:X509Data elements. r254.
