 - ct-test-embedded-with-preca-chain.pem
      Test certificate chains for Certificate Transparency: Each of these
      files contains a leaf certificate as the first certificate, which has
      embedded SCTs, followed by the issuer certificates chain.
      All files are from the src/test/testdada directory in
      https://code.google.com/p/certificate-transparency/

 - client-nokey.p12 : A PKCS #12 file containing a client certificate (the same
      as the one in client.p12) but no private key. The password is "12345".

 ===== 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.
