13 * The ordering of cipher suites in this table must match the ordering in
14 * the cipherSuites table in ssl3con.c.
15 *
16 * If new ECC cipher suites are added, also update the ssl3CipherSuite arrays
17 * in ssl3ecc.c.
18 *
19 * Finally, update the ssl_V3_SUITES_IMPLEMENTED macro in sslimpl.h.
20 *
21 * The ordering is as follows:
22 * * No-encryption cipher suites last
23 * * Export/weak/obsolete cipher suites before no-encryption cipher suites
24 * * Order by key exchange algorithm: ECDHE, then DHE, then ECDH, RSA.
25 * * Within key agreement sections, order by symmetric encryption algorithm:
26 * AES-128, then Camellia-128, then AES-256, then Camellia-256, then SEED,
27 * then FIPS-3DES, then 3DES, then RC4. AES is commonly accepted as a
28 * strong cipher internationally, and is often hardware-accelerated.
29 * Camellia also has wide international support across standards
30 * organizations. SEED is only recommended by the Korean government. 3DES
31 * only provides 112 bits of security. RC4 is now deprecated or forbidden
32 * by many standards organizations.
33 * * Within symmetric algorithm sections, order by message authentication
34 * algorithm: GCM, then HMAC-SHA1, then HMAC-SHA256, then HMAC-MD5.
35 * * Within message authentication algorithm sections, order by asymmetric
36 * signature algorithm: ECDSA, then RSA, then DSS.
37 *
38 * Exception: Because some servers ignore the high-order byte of the cipher
39 * suite ID, we must be careful about adding cipher suites with IDs larger
40 * than 0x00ff; see bug 946147. For these broken servers, the first four cipher
41 * suites, with the MSB zeroed, look like:
42 * TLS_KRB5_EXPORT_WITH_RC4_40_MD5 { 0x00,0x2B }
43 * TLS_RSA_WITH_AES_128_CBC_SHA { 0x00,0x2F }
44 * TLS_RSA_WITH_3DES_EDE_CBC_SHA { 0x00,0x0A }
45 * TLS_RSA_WITH_DES_CBC_SHA { 0x00,0x09 }
46 * The broken server only supports the third and fourth ones and will select
47 * the third one.
