178 * without authentication, which would normally disabled by DEFAULT (due
179 * the "!ADH" being part of default). Therefore "RC4:!COMPLEMENTOFDEFAULT"
180 * will make sure that it is also disabled in the specific selection.
181 * COMPLEMENTOF* identifiers are portable between version, as adjustments
182 * to the default cipher setup will also be included here.
