Handle SEC_ERROR_UNTRUSTED_ISSUER
When verifying a PDF signed by a certificate issued by a CA not in the trust
store I would expect to get an error "Certificate isn't Trusted" however
currently the error message actually is the more generic "Unknown issue with
Certificate or corrupted data".
I tested with
<a href="http://wwwpriv.primekey.se/~markus/pdfsigner/test-pdfs/signserver-res-test-pdf/sample-signed.pdf">http://wwwpriv.primekey.se/~markus/pdfsigner/test-pdfs/signserver-res-test-pdf/sample-signed.pdf</a>:
[user@dev-21 utils]$ ./pdfsigverify
~/Downloads/signserver-res-test-pdf/sample-signed.pdf
Digital Signature Info of:
/home/user/Downloads/signserver-res-test-pdf/sample-signed.pdf
Signature #1:
- Signer Certificate Common Name: Signer 2
- Signing Time: Nov 23 2011 17:09:42
- Signature Validation: Signature is Valid.
- Certificate Validation: Unknown issue with Certificate or corrupted data.
Then after adding
<a href="http://wwwpriv.primekey.se/~markus/pdfsigner/test-pki/signserver-res-test-dss10/DSSRootCA10.cacert.pem">http://wwwpriv.primekey.se/~markus/pdfsigner/test-pki/signserver-res-test-dss10/DSSRootCA10.cacert.pem</a>
as trusted in Firefox:
[user@dev-21 utils]$ ./pdfsigverify
~/Downloads/signserver-res-test-pdf/sample-signed.pdf
Digital Signature Info of:
/home/user/Downloads/signserver-res-test-pdf/sample-signed.pdf
Signature #1:
- Signer Certificate Common Name: Signer 2
- Signing Time: Nov 23 2011 17:09:42
- Signature Validation: Signature is Valid.
- Certificate Validation: Certificate is Trusted.
The attached patch adds the NSS error code for untrusted issuer so the error
will be "Certificate isn't trusted".</pre>
