FIPS-MODE-SETUP(8)   FIPS-MODE-SETUP(8)

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.

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 (unsupported).

•--check: Checks the system FIPS mode status.

•--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.
