/*
 * The ciphers are listed in the following order:
 * - stronger ciphers before weaker ciphers
 * - national ciphers before international ciphers
 * - faster ciphers before slower ciphers
 *
 * National ciphers such as Camellia are listed before international ciphers
 * such as AES and RC4 to allow servers that prefer Camellia to negotiate
 * Camellia without having to disable AES and RC4, which are needed for
 * interoperability with clients that don't yet implement Camellia.
 *
 * 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.
