.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The OpenSSL \s-1FIPS\s0 provider is a special provider that conforms to the Federal
Information Processing Standards (\s-1FIPS\s0) specified in \s-1FIPS 140\-2.\s0 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:
.ie n .IP """provider=fips""" 4
.el .IP "``provider=fips''" 4
.IX Item "provider=fips"
.PD 0
.ie n .IP """fips=yes""" 4

.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
It isn't mandatory to query for any of these properties, except to
make sure to get implementations of this provider and none other.
.PP
The \*(L"fips=yes\*(R" property can be use to make sure only \s-1FIPS\s0 approved
implementations are used for crypto operations.  This may also include
other non-crypto support operations that are not in the \s-1FIPS\s0 provider,
such as asymmetric key encoders,
see \*(L"Asymmetric Key Management\*(R" in \fBOSSL_PROVIDER\-default\fR\|(7).

.SH "SELF TESTING"
.IX Header "SELF TESTING"
One of the requirements for the \s-1FIPS\s0 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 \s-1FIPS\s0 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 \s-1FIPS\s0 module passes the following type(s) to \fBOSSL_SELF_TEST_onbegin()\fR.

The \*(L"Install_Integrity\*(R" self test is used to check if the self tests have

All other self test categories are run once at installation time, except for the

.SH "NOTES"
.IX Header "NOTES"
Some released versions of OpenSSL do not include a validated
\&\s-1FIPS\s0 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 \s-1FIPS\s0
provider using one of the validated versions listed there.  Normally,
it is possible to utilize a \s-1FIPS\s0 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 \s-1FIPS\s0 boundary.
