I left this in this section since although the keychain file is generated by a
script, it's based on a real-world cert.

 ===== Manually generated certificates
 - client.p12 : A PKCS #12 file containing a client certificate and a private
      key created for testing.  The password is "12345".
 
 - 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".
 
 - unittest.selfsigned.der : A self-signed certificate generated using private
      key in unittest.key.bin. The common name is "unittest".

 ===== From net/data/ssl/scripts/generate-multi-root-test-chains.sh
 - multi-root-chain1.pem
 - multi-root-chain2.pem
      Two chains, A -> B -> C -> D and A -> B -> C2 -> E (C and C2 share the
      same public key) to test that certificate validation caching does not
      interfere with the chain_verify_callback used by CertVerifyProcChromeOS.
      See CertVerifyProcChromeOSTest.

 - duplicate_cn_1.pem
 - duplicate_cn_2.p12
 - duplicate_cn_2.pem
      Two certificates from the same issuer that share the same common name,
      but have distinct subject names (namely, their O fields differ). NSS
      requires that certificates have unique nicknames if they do not share the
      same subject, and these certificates are used to test that the nickname
      generation algorithm generates unique nicknames.

      aia-cert.pem has a caIssuers that points to "aia-test.invalid" as the URL

      aia-intermediate.der is stored in DER form for convenience, since that is
      the form expected of certificates discovered via AIA.
 
 ===== From net/data/ssl/scripts/generate-self-signed-certs.sh
  - self-signed-invalid-name.pem
  - self-signed-invalid-sig.pem
      Two "self-signed" certificates with mismatched names or an invalid
      signature, respectively.
