 - x509_verify_results.chain.pem : A simple certificate chain used to test that
     the correctly ordered, filtered certificate chain is returned during
     verification, regardless of the order in which the intermediate/root CA
     certificates are provided.
 
 - test_mail_google_com.pem : A certificate signed by the test CA for
     "mail.google.com". Because it is signed by that CA instead of the true CA

 ===== From net/data/ssl/scripts/generate-aia-certs.sh
 - aia-cert.pem
 - aia-intermediate.der
 - aia-root.pem
      A certificate chain which we use to ensure AIA fetching works correctly
      when using NSS to verify certificates (which uses our HTTP stack).
      aia-cert.pem has a caIssuers that points to "aia-test.invalid" as the URL
      containing the intermediate, which can be served via a URLRequestFilter.
      aia-intermediate.der is stored in DER form for convenience, since that is
      the form expected of certificates discovered via AIA.
