/*
* The ordering of cipher suites in this table must match the ordering in
* the cipherSuites table in ssl3con.c.
*
* If new ECC cipher suites are added, also update the ssl3CipherSuite arrays
* in ssl3ecc.c.
*
* Finally, update the ssl_V3_SUITES_IMPLEMENTED macro in sslimpl.h.
*
* The ordering is as follows:
* * No-encryption cipher suites last
* * Export/weak/obsolete cipher suites before no-encryption cipher suites
* * Order by key exchange algorithm: ECDHE, then DHE, then ECDH, RSA.
* * Within key agreement sections, prefer AEAD over non-AEAD cipher suites.
* * Within AEAD sections, order by symmetric encryption algorithm which
* integrates message authentication algorithm: AES-128-GCM, then
* ChaCha20-Poly1305, then AES-256-GCM,
* * Within non-AEAD sections, order by symmetric encryption algorithm:
* AES-128, then Camellia-128, then AES-256, then Camellia-256, then SEED,
* then FIPS-3DES, then 3DES, then RC4. AES is commonly accepted as a
* strong cipher internationally, and is often hardware-accelerated.
* Camellia also has wide international support across standards
* organizations. SEED is only recommended by the Korean government. 3DES
* only provides 112 bits of security. RC4 is now deprecated or forbidden
* by many standards organizations.
* * Within non-AEAD symmetric algorithm sections, order by message
* authentication algorithm: HMAC-SHA256, then HMAC-SHA384, then HMAC-SHA1,
* then HMAC-MD5.
* * Within symmetric algorithm sections, order by message authentication
* algorithm: GCM, then HMAC-SHA1, then HMAC-SHA256, then HMAC-MD5.
* * Within message authentication algorithm sections, order by asymmetric
* signature algorithm: ECDSA, then RSA, then DSS.
* * As a special case, the PSK ciphers, which are only enabled when
* TLS 1.3 PSK-resumption is in use, come first.
*
* Exception: Because some servers ignore the high-order byte of the cipher
* suite ID, we must be careful about adding cipher suites with IDs larger
* than 0x00ff; see bug 946147. For these broken servers, the first three
* cipher suites, with the MSB zeroed, look like:
* TLS_RSA_WITH_AES_128_CBC_SHA { 0x00,0x2F }
* TLS_RSA_WITH_3DES_EDE_CBC_SHA { 0x00,0x0A }
* TLS_RSA_WITH_DES_CBC_SHA { 0x00,0x09 }
* The broken server only supports the third and fourth ones and will select
* the third one.
