/*
 * Keep CBC modes in the back of the client default cipher list for backward
 * compatibility but remove them from the server side because there are some
 * potential security issues with those modes regarding SSH protocol version 2.
 * Since the client is the one who picks the cipher from the list offered by the
 * server the only way to force the client not to use CBC modes is not to
 * advertise those at all. Note that we still support all such CBC modes in the
 * server code, this is about the default server cipher list only. The list can
 * be changed in the Ciphers option in the sshd_config(4) file.
 *
 * Note that the ordering of ciphers on the server side is not relevant but we
 * must do it properly even here so that we can use the macro for the client
 * list as well.
