+The value is a boolean that can be B<yes> or B<no>.  If the value is
+B<yes>, this is exactly equivalent to:

+These two commands should not be used together, as there is no control

+The use of B<fips_mode> is strongly discouraged and is only present
+for backward compatibility with earlier OpenSSL FIPS modules.
