 - verisign_intermediate_ca_2016.pem : Certificates for testing two
      X509Certificate objects that contain the same server certificate but
      different intermediate CA certificates.  The two intermediate CA
      certificates actually represent the same intermediate CA but have
      different validity periods.

-     These certificates are reflect a portion of the CyberTrust (Verizon
-     Business) CA hierarchy. _gte_root.pem is a legacy 1024-bit root that is
-     still widely supported, while _baltimore_root.pem reflects the newer
-     2048-bit root. For clients that only support the GTE root, two versions
-     of the Baltimore root were cross-signed by GTE, namely
-     _cross_certified_[1,2].pem. _omniroot_chain.pem contains a certificate
-     chain that was issued under the Baltimore root. Combined, these
-     certificates can be used to test real-world cross-signing; in practice,
-     they are used to test certain workarounds for OS X's chain building code.

 - ndn.ca.crt: "New Dream Network Certificate Authority" root certificate.
      This is an X.509 v1 certificate that omits the version field. Used to
      test that the certificate version gets the default value v1.

 ===== 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.
