1.16 + * The ordering of cipher suites in this table must match the ordering in
1.17 + * the cipherSuites table in ssl3con.c.
1.18 + *
1.19 + * If new ECC cipher suites are added, also update the ssl3CipherSuite arrays
1.20 + * in ssl3ecc.c.
1.21 + *
1.22 + * Finally, update the ssl_V3_SUITES_IMPLEMENTED macro in sslimpl.h.
1.23 + *
1.24 + * The ordering is as follows:
1.25 + * * No-encryption cipher suites last
1.26 + * * Export/weak/obsolete cipher suites before no-encryption cipher suites
1.27 + * * Order by key exchange algorithm: ECDHE, then DHE, then ECDH, RSA.
1.28 + * * Within key agreement sections, order by symmetric encryption algorithm:
1.29 + * AES-128, then Camellia-128, then AES-256, then Camellia-256, then SEED,
1.30 + * then FIPS-3DES, then 3DES, then RC4. AES is commonly accepted as a
1.31 + * strong cipher internationally, and is often hardware-accelerated.
1.32 + * Camellia also has wide international support across standards
1.33 + * organizations. SEED is only recommended by the Korean government. 3DES
1.34 + * only provides 112 bits of security. RC4 is now deprecated or forbidden
1.35 + * by many standards organizations.
1.36 + * * Within symmetric algorithm sections, order by message authentication
1.37 + * algorithm: GCM, then HMAC-SHA1, then HMAC-SHA256, then HMAC-MD5.
1.38 + * * Within message authentication algorithm sections, order by asymmetric
1.39 + * signature algorithm: ECDSA, then RSA, then DSS.
1.40 + *
1.41 + * Exception: Because some servers ignore the high-order byte of the cipher
1.42 + * suite ID, we must be careful about adding cipher suites with IDs larger
1.43 + * than 0x00ff; see bug 946147. For these broken servers, the first four cipher
1.44 + * suites, with the MSB zeroed, look like:
1.45 + * TLS_KRB5_EXPORT_WITH_RC4_40_MD5 { 0x00,0x2B }
1.46 + * TLS_RSA_WITH_AES_128_CBC_SHA { 0x00,0x2F }
1.47 + * TLS_RSA_WITH_3DES_EDE_CBC_SHA { 0x00,0x0A }
1.48 + * TLS_RSA_WITH_DES_CBC_SHA { 0x00,0x09 }
1.49 + * The broken server only supports the third and fourth ones and will select
1.50 + * the third one.
