+=head1 DESCRIPTION
+
+The service level indicator has two different usage scenarios.
+
+=over 1
+
+=item C<int fips_sli_is_approved_*_CTX(...)>
+
+Most operations happen on some form of a context, which also holds the SLI.
+This function returns whether the FIPS SLI indicates an approved operation or not.
+
+After a disapproved operation is encountered, the SLI will continue to indicate this disapproved state. The SLI can only
+be reset by the various existing resetting functions such as C<EVP_MD_CTX_reset(EVP_MD_CTX *ctx)> or reinitializing the
+context, e.g. via L<EVP_DigestInit(3)>.
+
+=item C<int fips_sli_*_is_approved(...)>
+
+Operations without a context (standalone functions) have a separate SLI with the name fips_sli_FNNAME_is_approved().
+These indicator functions take the same parameters as their corresponding operation
+and may modify them just like their corresponding function might do.
+
+In order to check the SLI status of an operation C<FNNAME()>, the function
+C<fips_sli_FNNAME_is_approved()> must be called with the same set of parameters as C<FNNAME()>.
+Note that applications must check the return value of C<FNNAME()> according to its documentation B<as well as> the return value of the SLI (see below for L</RETURN VALUES>).
+Both are orthogonal: the former reports about success and failure of C<FNNAME()>, and the latter whether a disapproved operation happened or not.
+Well-behaving applications check for both.
+
+The following explicit indicators exist:

+=head1 Notes on the RNG
+
+OpenSSL 1.1.1l implements a CTR DRBG with AES 128/192/256 (defaults to AES-256).
+See L<RAND_bytes(3)>/RAND_priv_bytes().
+
+Swapping out OPENSSL's RNG implementation (e.g. via L<RAND_set_rand_method(3)>) is NOT allowed.
+
+=head1 RETURN VALUES
+
+C<fips_sli_is_approved_*_CTX()> returns 0 if the previous operation(s) was unapproved or B<ctx> was B<NULL>, and returns 1
+if the previous operation(s) were approved (or rather, no non-approved operations happened).
+
+C<fips_sli_*_is_approved()> returns 0 if an operation with a given set of parameters was unapproved, and returns 1
+if the operation is approved with the given set of parameters.
+
+These functions can be invoked at any time.
+
+=head1 HISTORY
+
+The FIPS SLI was added in OpenSSL 1.1.1.l.
