README-PROVIDERS files, as well as the migration guide.
The FIPS provider is disabled by default and needs to be enabled explicitly
at configuration time using the `enable-fips` option. If it is enabled,
the FIPS provider gets built and installed in addition to the default and
the legacy provider. No separate installation procedure is necessary.
There is however a dedicated `install_fips` make target, which serves the
special purpose of installing only the FIPS provider into an existing
OpenSSL installation.
