fips-mode-setup(8)
==================
:doctype: manpage
:man source: fips-mode-setup


NAME
----
fips-mode-setup - Check or enable the system FIPS mode.


SYNOPSIS
--------
*fips-mode-setup* ['COMMAND']


DESCRIPTION
-----------
fips-mode-setup(8) is used to check and control the system FIPS mode.

When enabling the system FIPS mode, the command completes the installation
of FIPS modules if needed by calling 'fips-finish-install' and changes the
system crypto policy to FIPS
(unless the policy has already been set to FIPS plus subpolicies on top,
in which case the currently active subpolicies is retained).

Then the command modifies the boot loader configuration to add
'fips=1' and 'boot=<boot-device>' options to the kernel command line.

When disabling the system FIPS mode the system crypto policy is switched
to DEFAULT and the kernel command line option 'fips=0' is set.

OPTIONS
-------

The following options are available in fips-mode-setup tool.

* --enable:     Enables the system FIPS mode.

* --disable:    Undo some of the FIPS-enablement steps.
                Please note that module installation cannot be undone
                without reformatting of and overwriting, at least once,
                the platform’s hard drive or other permanent storage media.
                This option is not meant to be used in production,
                is not supported, and is implemented for testing purposes only.

* --check:      Checks for inconsistently enabled FIPS mode.
                Exits successfully (0) for both consistently-enabled FIPS mode
                and consistently-disabled FIPS mode,
                returns error code (1) if inconsistencies are detected.
                For checking whether FIPS mode is enabled,
                see --is-enabled below.

* --is-enabled: Checks the system FIPS mode status and returns failure
                error code if disabled (2) or inconsistent (1).

* --no-bootcfg: The tool will not reconfigure the boot loader,
                and, instead, will print the options that need
                to be added to the kernel command line.
                Exception: it still attempts executing zipl(8) on s390x,
                as the system might become unbootable otherwise.
