 * - 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.
 *
 * If new ECC cipher suites are added, also update the ssl3CipherSuite arrays
 * in ssl3ecc.c.
