- Authentication string. If this needs to be hidden(for md5 type), the string
should be 7 followed by the key string. Otherwise, it can be 0 followed by
key string or just key string (for backward compatibility). For text type,
this should be just be a key string. if this is 'default', authentication
is removed.
