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