fips-mode-setup [COMMAND]

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.

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

• --enable: Enables the system FIPS mode.
• --disable: Disables the system FIPS mode.
• --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 attempt to change the boot loader configuration and it just prints the options that need to be added to the kernel command line.
