     certificate and a encrypted private key.  The password is the empty string,
     encoded as two zero bytes.  (PKCS#12 passwords are encoded as
     NUL-terminated UTF-16.)

     certificate and a encrypted private key.  The password is the empty string,
     encoded as the empty byte string.

  issuer/subject unique IDs. This certificate should only be used in parsing
  tests and otherwise kept fixed. The signature, etc., are intentionally
  invalid.

  The private key matching the public_key_hash of the kDomainsTest constraint
  in CertVerifyProc::HasNameConstraintsViolation.

     This isn't generated and just contains a simple text file (the contents
     don't actually matter, just the presence of the file).

   root do not actually form a chain.)

   enforcement requiring Certificate Transparency for new certificates. This
   certificate does not have any embedded SCTs.

===== From net/data/ssl/scripts/generate-redundant-test-chains.sh
- redundant-validated-chain.pem
- redundant-server-chain.pem
- redundant-validated-chain-root.pem

     Two chains, A -> B -> C -> D and A -> B -> C2 (C and C2 share the same
     public key) to test that SSLInfo gets the reconstructed, re-ordered
     chain instead of the chain as served. See
     SSLClientSocketTest.VerifyReturnChainProperlyOrdered in
     net/socket/ssl_client_socket_unittest.cc. These chains are valid until
     26 Feb 2022 and are generated by
     net/data/ssl/scripts/generate-redundant-test-chains.sh.

===== From net/data/ssl/scripts/generate-client-certificates.sh
- client_1.pem
- client_1.key
- client_1.pk8
- client_1_ca.pem
- client_2.pem
- client_2.key
- client_2.pk8
- client_2_ca.pem
- client_3.pem
- client_3.key
- client_3.pk8
- client_3_ca.pem
- client_4.pem
- client_4.key
- client_4.pk8
- client_4_ca.pem
- client_5.pem
- client_5.key
- client_5.pk8
- client_5_ca.pem
- client_6.pem
- client_6.key
- client_6.pk8
- client_6_ca.pem
- client_root_ca.pem
     This is a set of files used to unit test SSL client certificate
     authentication.
     - client_1_ca.pem and client_2_ca.pem are the certificates of
       two distinct signing CAs.
     - client_1.pem and client_1.key correspond to the certificate and
       private key for a first certificate signed by client_1_ca.pem.
     - client_2.pem and client_2.key correspond to the certificate and
       private key for a second certificate signed by client_2_ca.pem.
     - each .pk8 file contains the same key as the corresponding .key file
       as PKCS#8 PrivateKeyInfo in DER encoding.
     - client_3.pem is nearly identical to client_2.pem, except it is used
       to test wifi EAP-TLS authentication so it uses a different set
       of X509v3 extensions.  Specifically it includes two Subject
       Alternative Name fields recognized by Chrome OS.
     - client_4.pem is similar to client_2.pem but is a P-256 ECDSA key rather
       than RSA.
     - client_5.pem is similar to client_2.pem but is a P-384 ECDSA key rather
       than RSA.
     - client_6.pem is similar to client_2.pem but is a P-521 ECDSA key rather
       than RSA.
     - client_root_ca.pem is the CA certificate which signed client_*_ca.pem.

===== From net/data/ssl/scripts/generate-bad-eku-certs.sh
- eku-test-root.pem
- non-crit-codeSigning-chain.pem
- crit-codeSigning-chain.pem
     Two code-signing certificates (eKU: codeSigning; eKU: critical,
     codeSigning) which we use to test that clients are making sure that web
     server certs are checked for correct eKU fields (when an eKU field is
     present). Since codeSigning is not valid for web server auth, the checks
     should fail.

===== 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.

===== From net/data/ssl/scripts/generate-multi-root-BFE-keychain.sh
- multi-root-BFE.keychain: An OSX Keychain containing the generated
  certificates "multi-root-B-by-F.pem" and "multi-root-F-by-E.pem".
- multi-root.keychain: An OSX Keychain containing the generated
  certificates multi-root-*-by-*.pem

===== From net/data/ssl/scripts/generate-duplicate-cn-certs.sh
- duplicate_cn_1.p12
- 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.
     The .pem versions contain just the certs, while the .p12 versions contain
     both the cert and a private key, since there are multiple ways to import
     certificates into NSS.

===== 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.

===== From net/data/ssl/scripts/generate-key-usage-certs.sh
- key_usage_rsa_no_extension.pem
- key_usage_rsa_keyencipherment.pem
- key_usage_rsa_digitalsignature.pem
- key_usage_rsa_both.pem
     Self-signed RSA certificates with various combinations of keyUsage
     flags. Their private key is key_usage_rsa.key.

- key_usage_p256_no_extension.pem
- key_usage_p256_keyagreement.pem
- key_usage_p256_digitalsignature.pem
- key_usage_p256_both.pem
     Self-signed P-256 certificates with various combinations of keyUsage
     flags. Their private key is key_usage_p256.key.
