-//
-// The list is sorted by applying the following priority rules, stopping at the

-//
-//   - Anything else comes before RC4
-//
-//     RC4 has practically exploitable biases. See https://www.rc4nomore.com.
-//
-//   - Anything else comes before CBC_SHA256
-//
-//     SHA-256 variants of the CBC ciphersuites don't implement any Lucky13
-//     countermeasures. See http://www.isg.rhul.ac.uk/tls/Lucky13.html and
-//     https://www.imperialviolet.org/2013/02/04/luckythirteen.html.
-//
-//   - Anything else comes before 3DES
-//
-//     3DES has 64-bit blocks, which makes it fundamentally susceptible to
-//     birthday attacks. See https://sweet32.info.
-//
-//   - ECDHE comes before anything else
-//
-//     Once we got the broken stuff out of the way, the most important
-//     property a cipher suite can have is forward secrecy. We don't
-//     implement FFDHE, so that means ECDHE.
-//
-//   - AEADs come before CBC ciphers
-//
-//     Even with Lucky13 countermeasures, MAC-then-Encrypt CBC cipher suites
-//     are fundamentally fragile, and suffered from an endless sequence of
-//     padding oracle attacks. See https://eprint.iacr.org/2015/1129,
-//     https://www.imperialviolet.org/2014/12/08/poodleagain.html, and
-//     https://blog.cloudflare.com/yet-another-padding-oracle-in-openssl-cbc-ciphersuites/.
-//
-//   - AES comes before ChaCha20
-//
-//     When AES hardware is available, AES-128-GCM and AES-256-GCM are faster
-//     than ChaCha20Poly1305.
-//
-//     When AES hardware is not available, AES-128-GCM is one or more of: much
-//     slower, way more complex, and less safe (because not constant time)
-//     than ChaCha20Poly1305.
-//
-//     We use this list if we think both peers have AES hardware, and
-//     cipherSuitesPreferenceOrderNoAES otherwise.
-//
-//   - AES-128 comes before AES-256
-//
-//     The only potential advantages of AES-256 are better multi-target
-//     margins, and hypothetical post-quantum properties. Neither apply to
-//     TLS, and AES-256 is slower due to its four extra rounds (which don't
-//     contribute to the advantages above).
-//
-//   - ECDSA comes before RSA
-//
-//     The relative order of ECDSA and RSA cipher suites doesn't matter,
-//     as they depend on the certificate. Pick one to get a stable order.
