.SH NAME
OSSL_PROVIDER\-FIPS \- OpenSSL FIPS provider
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The OpenSSL FIPS provider is a special provider that conforms to the Federal
Information Processing Standards (FIPS) specified in FIPS 140\-3. This 'module'
contains an approved set of cryptographic algorithms that is validated by an
accredited testing laboratory.
.SS Properties
.IX Subsection "Properties"
The implementations in this provider specifically have these properties
defined:
.IP """provider=fips""" 4
.IX Item """provider=fips"""
.PD 0
.IP """fips=yes""" 4
.IX Item """fips=yes"""
.PD
.PP
It may be used in a property query string with fetching functions such as
\&\fBEVP_MD_fetch\fR\|(3) or \fBEVP_CIPHER_fetch\fR\|(3), as well as with other
functions that take a property query string, such as
\&\fBEVP_PKEY_CTX_new_from_name\fR\|(3).
.PP
To be FIPS compliant, it is mandatory to include \f(CW\*(C`fips=yes\*(C'\fR as
part of all property queries.  This ensures that only FIPS approved
implementations are used for cryptographic operations.  The \f(CW\*(C`fips=yes\*(C'\fR
query may also include other non-crypto support operations that
are not in the FIPS provider, such as asymmetric key encoders, see
"Asymmetric Key Management" in \fBOSSL_PROVIDER\-default\fR\|(7).
.PP
It is not mandatory to include \f(CW\*(C`provider=fips\*(C'\fR as part of your property
query.  Including \f(CW\*(C`provider=fips\*(C'\fR in your property query guarantees
that the OpenSSL FIPS provider is used for cryptographic operations
rather than other FIPS capable providers.
.SS "Provider parameters"
.IX Subsection "Provider parameters"
See "Provider parameters" in \fBprovider\-base\fR\|(7) for a list of base parameters.
Additionally the OpenSSL FIPS provider also supports the following gettable
parameters:
.IP """security-checks"" (\fBOSSL_OSSL_PROV_PARAM_SECURITY_CHECKS\fR) <unsigned integer>" 4
.IX Item """security-checks"" (OSSL_OSSL_PROV_PARAM_SECURITY_CHECKS) <unsigned integer>"

.SH "SELF TESTING"
.IX Header "SELF TESTING"
One of the requirements for the FIPS module is self testing. An optional callback
mechanism is available to return information to the user using
\&\fBOSSL_SELF_TEST_set_callback\fR\|(3).
.PP
The parameters passed to the callback are described in \fBOSSL_SELF_TEST_new\fR\|(3)
.PP
The OpenSSL FIPS module uses the following mechanism to provide information
about the self tests as they run.
This is useful for debugging if a self test is failing.
The callback also allows forcing any self test to fail, in order to check that
it operates correctly on failure.
Note that all self tests run even if a self test failure occurs.
.PP
The FIPS module passes the following type(s) to \fBOSSL_SELF_TEST_onbegin()\fR.
.IP """Module_Integrity"" (\fBOSSL_SELF_TEST_TYPE_MODULE_INTEGRITY\fR)" 4
.IX Item """Module_Integrity"" (OSSL_SELF_TEST_TYPE_MODULE_INTEGRITY)"
Uses HMAC SHA256 on the module file to validate that the module has not been
modified. The integrity value is compared to a value written to a configuration
file during installation.
.IP """Install_Integrity"" (\fBOSSL_SELF_TEST_TYPE_INSTALL_INTEGRITY\fR)" 4
.IX Item """Install_Integrity"" (OSSL_SELF_TEST_TYPE_INSTALL_INTEGRITY)"
Uses HMAC SHA256 on a fixed string to validate that the installation process
has already been performed and the self test KATS have already been tested,
The integrity value is compared to a value written to a configuration
file after successfully running the self tests during installation.
.IP """KAT_Cipher"" (\fBOSSL_SELF_TEST_TYPE_KAT_CIPHER\fR)" 4
.IX Item """KAT_Cipher"" (OSSL_SELF_TEST_TYPE_KAT_CIPHER)"
Known answer test for a symmetric cipher.
.IP """KAT_AsymmetricCipher"" (\fBOSSL_SELF_TEST_TYPE_KAT_ASYM_CIPHER\fR)" 4
.IX Item """KAT_AsymmetricCipher"" (OSSL_SELF_TEST_TYPE_KAT_ASYM_CIPHER)"
Known answer test for a asymmetric cipher.
.IP """KAT_Digest"" (\fBOSSL_SELF_TEST_TYPE_KAT_DIGEST\fR)" 4

Known answer test for a digest.

Known answer test for a signature.

Known answer test for a key derivation function.
.IP """KAT_KA"" (\fBOSSL_SELF_TEST_TYPE_KAT_KA\fR)" 4

Known answer test for key agreement.
.IP """DRBG"" (\fBOSSL_SELF_TEST_TYPE_DRBG\fR)" 4

Known answer test for a Deterministic Random Bit Generator.
.IP """Conditional_PCT"" (\fBOSSL_SELF_TEST_TYPE_PCT\fR)" 4

Conditional test that is run during the generation of key pairs.
.IP """Continuous_RNG_Test"" (\fBOSSL_SELF_TEST_TYPE_CRNG\fR)" 4
.IX Item """Continuous_RNG_Test"" (OSSL_SELF_TEST_TYPE_CRNG)"
Continuous random number generator test.
.PP
The "Module_Integrity" self test is always run at startup.
The "Install_Integrity" self test is used to check if the self tests have
already been run at installation time. If they have already run then the
self tests are not run on subsequent startups.
All other self test categories are run once at installation time, except for the
"Pairwise_Consistency_Test".
.PP
There is only one instance of the "Module_Integrity" and "Install_Integrity"
self tests. All other self tests may have multiple instances.

.SH NOTES
.IX Header "NOTES"
Some released versions of OpenSSL do not include a validated
FIPS provider.  To determine which versions have undergone
the validation process, please refer to the
OpenSSL Downloads page <https://www.openssl.org/source/>.  If you
require FIPS-approved functionality, it is essential to build your FIPS
provider using one of the validated versions listed there.  Normally,
it is possible to utilize a FIPS provider constructed from one of the
validated versions alongside \fIlibcrypto\fR and \fIlibssl\fR compiled from any
release within the same major release series.  This flexibility enables
you to address bug fixes and CVEs that fall outside the FIPS boundary.

The FIPS provider in OpenSSL 3.1 includes some non-FIPS validated algorithms,
consequently the property query \f(CW\*(C`fips=yes\*(C'\fR is mandatory for applications that
want to operate in a FIPS approved manner.  The algorithms are:
.IP "Triple DES ECB" 4
.IX Item "Triple DES ECB"
.PD 0
.IP "Triple DES CBC" 4
.IX Item "Triple DES CBC"
.IP EdDSA 4
.IX Item "EdDSA"
.PD
