| * 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, 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 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. |
| * |
| * 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 four cipher |
| * suites, with the MSB zeroed, look like: |
| * TLS_KRB5_EXPORT_WITH_RC4_40_MD5 { 0x00,0x2B } |
| * 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. |
