=head1 NAME
|
|
|
|
fips_config - OpenSSL FIPS configuration
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
A separate configuration file, using the OpenSSL L<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:
|
|
|
|
=over 4
|
|
|
|
=item - 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.
|
|
|
|
=item - Verify the module's checksum.
|
|
|
|
This is done each time the module is used.
|
|
|
|
=back
|
|
|
|
This file is generated by the L<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 B<fips> option in the B<providers>
|
|
section, as described in L<config(5)/Provider Configuration Module>.
|
|
|
|
=over 4
|
|
|
|
=item B<activate>
|
|
|
|
If present, the module is activated. The value assigned to this name is not
|
|
significant.
|
|
|
|
=item B<install-version>
|
|
|
|
A version number for the fips install process. Should be 1.
|
|
|
|
=item B<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 C<0> allows the error mode to not be triggered if any
|
|
continuous test fails. The default value of C<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.
|
|
|
|
=item B<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.
|
|
|
|
=item B<module-mac>
|
|
|
|
The calculated MAC of the FIPS provider file.
|
|
|
|
=item B<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.
|
|
|
|
=item B<install-mac>
|
|
|
|
A MAC of the value of the B<install-status> option, to prevent accidental
|
|
changes to that value.
|
|
It is written-to at the same time as B<install-status> is updated.
|
|
|
|
=back
|
|
|
|
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
|
|
|
|
=head1 NOTES
|
|
|
|
When using the FIPS provider, it is recommended that the
|
|
B<config_diagnostics> option is enabled to prevent accidental use of
|
|
non-FIPS validated algorithms via broken or mistaken configuration.
|
|
See L<config(5)>.
