// avoid unacceptably weak suites (e.g., those with bulk cipher secret key shorter than 128
// bits), while maintaining the capability to connect to the majority of servers.
//
// Cipher suites are listed in preference order (favorite choice first) of the client. However,
// servers are not required to honor the order. The key rules governing the preference order
// are:
// * Prefer Forward Secrecy (i.e., cipher suites that use ECDHE and DHE for key agreement).
// * Prefer ChaCha20-Poly1305 to AES-GCM unless hardware support for AES is available.
// * Prefer AES-GCM to AES-CBC whose MAC-pad-then-encrypt approach leads to weaknesses (e.g.,
// Lucky 13).
// * Prefer 128-bit bulk encryption to 256-bit one, because 128-bit is safe enough while
// consuming less CPU/time/energy.
//
// NOTE: Removing cipher suites from this list needs to be done with caution, because this may
// prevent apps from connecting to servers they were previously able to connect to.
