FIPS_CONFIG(5SSL) OpenSSL FIPS_CONFIG(5SSL)

NAME
fips_config - OpenSSL FIPS configuration

DESCRIPTION
A separate configuration file, using the OpenSSL config(5) syntax, is used to hold
information about the FIPS module. This includes a digest of the shared library file, and
status about the self-testing. This data is used automatically by the module itself for
two purposes:

- Run the startup FIPS self-test known answer tests (KATS).
This is normally done once, at installation time, but may also be set up to run each
time the module is used.

- Verify the module's checksum.
This is done each time the module is used.

This file is generated by the openssl-fipsinstall(1) program, and used internally by the
FIPS module during its initialization.

The following options are supported. They should all appear in a section whose name is
identified by the fips option in the providers section, as described in "Provider
Configuration Module" in config(5).

activate
If present, the module is activated. The value assigned to this name is not
significant.

install-version
A version number for the fips install process. Should be 1.

conditional-errors
The FIPS module normally enters an internal error mode if any self test fails. Once
this error mode is active, no services or cryptographic algorithms are accessible from
this point on. Continuous tests are a subset of the self tests (e.g., a key pair test
during key generation, or the CRNG output test). Setting this value to 0 allows the
error mode to not be triggered if any continuous test fails. The default value of 1
will trigger the error mode. Regardless of the value, the operation (e.g., key
generation) that called the continuous test will return an error code if its
continuous test fails. The operation may then be retried if the error mode has not
been triggered.

security-checks
This indicates if run-time checks related to enforcement of security parameters such
as minimum security strength of keys and approved curve names are used. A value of
'1' will perform the checks, otherwise if the value is '0' the checks are not
performed and FIPS compliance must be done by procedures documented in the relevant
Security Policy.

module-mac
The calculated MAC of the FIPS provider file.

install-status
An indicator that the self-tests were successfully run. This should only be written
after the module has successfully passed its self tests during installation. If this
field is not present, then the self tests will run when the module loads.

install-mac
A MAC of the value of the install-status option, to prevent accidental changes to that
value. It is written-to at the same time as install-status is updated.

For example:

[fips_sect]
activate = 1
install-version = 1
conditional-errors = 1
security-checks = 1
module-mac = 41:D0:FA:C2:5D:41:75:CD:7D:C3:90:55:6F:A4:DC
install-mac = FE:10:13:5A:D3:B4:C7:82:1B:1E:17:4C:AC:84:0C
install-status = INSTALL_SELF_TEST_KATS_RUN

NOTES
When using the FIPS provider, it is recommended that the config_diagnostics option is
enabled to prevent accidental use of non-FIPS validated algorithms via broken or mistaken
configuration. See config(5).
