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: + +C<int fips_sli_SHA1_is_approved(const unsigned char *d, size_t n, unsigned char *md);> + +C<int fips_sli_HMAC_is_approved(const EVP_MD *evp_md, const void *key, int key_len, const unsigned char *d, size_t n, unsigned char *md, unsigned int *md_len);> + +C<int fips_sli_PKCS5_PBKDF2_HMAC_is_approved(const char *pass, int passlen, const unsigned char *salt, int saltlen, int iter, const EVP_MD *digest, int keylen, unsigned char *out);> + +C<int fips_sli_RAND_bytes_is_approved(unsigned char *buf, int num);> + +C<int fips_sli_RAND_priv_bytes_is_approved(unsigned char *buf, int num);> + +=back + +=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. + +=head1 COPYRIGHT + +Copyright 2022 + +Licensed under the OpenSSL license (the "License").
