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.
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.
module-mac
The calculated MAC of the FIPS provider file.
install-version
A version number for the fips install process. Should be 1.
install-status
This field is deprecated and is no longer used.
install-mac
This field is deprecated and is no longer used.
FIPS indicator options
The following FIPS configuration options indicate if run-time checks
related to enforcement of FIPS 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.

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).
