fips_config - OpenSSL FIPS configuration

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:

This is normally done once, at installation time, but may also be set up to run each time the module is used.
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).

If present, the module is activated. The value assigned to this name is not significant.
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.
The calculated MAC of the FIPS provider file.
A version number for the fips install process. Should be 1.

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.

See "OPTIONS" in openssl-fipsinstall(1) for further information related to these options.

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

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).
