     13  * The ciphers are listed in the following order:
     14  * - stronger ciphers before weaker ciphers
     15  * - national ciphers before international ciphers
     16  * - faster ciphers before slower ciphers
     17  *
     18  * National ciphers such as Camellia are listed before international ciphers
     19  * such as AES and RC4 to allow servers that prefer Camellia to negotiate
     20  * Camellia without having to disable AES and RC4, which are needed for
     21  * interoperability with clients that don't yet implement Camellia.
     22  *
     23  * The ordering of cipher suites in this table must match the ordering in
     24  * the cipherSuites table in ssl3con.c.
     25  *
     26  * If new ECC cipher suites are added, also update the ssl3CipherSuite arrays
     27  * in ssl3ecc.c.
     28  *
     29  * Finally, update the ssl_V3_SUITES_IMPLEMENTED macro in sslimpl.h.
