OpenSSL FIPS support
|
|
====================
|
|
|
|
This release of OpenSSL includes a cryptographic module that is intended to be
|
|
FIPS 140-2 validated. The module is implemented as an OpenSSL provider.
|
|
A provider is essentially a dynamically loadable module which implements
|
|
cryptographic algorithms, see the [README-PROVIDERS](README-PROVIDERS.md) file
|
|
for further details.
|
|
|
|
The OpenSSL FIPS provider comes as shared library called `fips.so` (on Unix)
|
|
resp. `fips.dll` (on Windows). The FIPS provider does not get built and
|
|
installed automatically. To enable it, you need to configure OpenSSL using
|
|
the `enable-fips` option.
|
|
|
|
Installing the FIPS module
|
|
==========================
|
|
|
|
If the FIPS provider is enabled, it gets installed automatically during the
|
|
normal installation process. Simply follow the normal procedure (configure,
|
|
make, make test, make install) as described in the [INSTALL](INSTALL.md) file.
|
|
|
|
For example, on Unix the final command
|
|
|
|
$ make install
|
|
|
|
effectively executes the following install targets
|
|
|
|
$ make install_sw
|
|
$ make install_ssldirs
|
|
$ make install_docs
|
|
$ make install_fips # for `enable-fips` only
|
|
|
|
The `install_fips` make target can also be invoked explicitly to install
|
|
the FIPS provider independently, without installing the rest of OpenSSL.
|
|
|
|
The Installation of the FIPS provider consists of two steps. In the first step,
|
|
the shared library is copied to its installed location, which by default is
|
|
|
|
/usr/local/lib/ossl-modules/fips.so on Unix, and
|
|
C:\Program Files\OpenSSL\lib\ossl-modules\fips.dll on Windows.
|
|
|
|
In the second step, the `openssl fipsinstall` command is executed, which completes
|
|
the installation by doing the following two things:
|
|
|
|
- Runs the FIPS module self tests
|
|
- Generates the so-called FIPS module configuration file containing information
|
|
about the module such as the self test status, and the module checksum.
|
|
|
|
The FIPS module must have the self tests run, and the FIPS module config file
|
|
output generated on every machine that it is to be used on. You must not copy
|
|
the FIPS module config file output data from one machine to another.
|
|
|
|
On Unix the `openssl fipsinstall` command will be invoked as follows by default:
|
|
|
|
$ openssl fipsinstall -out /usr/local/ssl/fipsmodule.cnf -module /usr/local/lib/ossl-modules/fips.so
|
|
|
|
If you configured OpenSSL to be installed to a different location, the paths will
|
|
vary accordingly. In the rare case that you need to install the fipsmodule.cnf
|
|
to non-standard location, you can execute the `openssl fipsinstall` command manually.
|
|
|
|
Using the FIPS Module in applications
|
|
=====================================
|
|
|
|
Documentation about using the FIPS module is available on the [fips_module(7)]
|
|
manual page.
