.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "OSSL_STORE_SEARCH 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

For example, this can be useful for an application that has received a \s-1URI\s0 and then wants to add on search criteria in a uniform and supported manner. Subsection "Types" \fB\s-1OSSL_STORE_SEARCH\s0 is an opaque type that holds the constructed search criterion, and that can be given to an \s-1OSSL_STORE\s0 context with \fBOSSL_STORE_find().

The calling application owns the allocation of an \s-1OSSL_STORE_SEARCH\s0 at all times, and should therefore be careful not to deallocate it before \fBOSSL_STORE_close() has been called for the \s-1OSSL_STORE\s0 context it was given to.

Subsection "Application Functions" \fBOSSL_STORE_SEARCH_by_name(), \fBOSSL_STORE_SEARCH_by_issuer_serial(), \fBOSSL_STORE_SEARCH_by_key_fingerprint(), and OSSL_STORE_SEARCH_by_alias() are used to create an \s-1OSSL_STORE_SEARCH\s0 from a subject name, an issuer name and serial number pair, a key fingerprint, and an alias (for example a friendly name). The parameters that are provided are not copied, only referred to in a criterion, so they must have at least the same life time as the created \fB\s-1OSSL_STORE_SEARCH\s0.

\fBOSSL_STORE_SEARCH_free() is used to free the \s-1OSSL_STORE_SEARCH\s0.

Subsection "Loader Functions" \fBOSSL_STORE_SEARCH_get_type() returns the criterion type for the given \fB\s-1OSSL_STORE_SEARCH\s0.

\fBOSSL_STORE_SEARCH_get0_name(), OSSL_STORE_SEARCH_get0_serial(), \fBOSSL_STORE_SEARCH_get0_bytes(), OSSL_STORE_SEARCH_get0_string(), and OSSL_STORE_SEARCH_get0_digest() are used to retrieve different data from a \s-1OSSL_STORE_SEARCH\s0, as available for each type. For more information, see \*(L"\s-1SUPPORTED CRITERION TYPES\*(R"\s0 below.

Header "SUPPORTED CRITERION TYPES" Currently supported criterion types are: Item "OSSL_STORE_SEARCH_BY_NAME" This criterion supports a search by exact match of subject name. The subject name itself is a X509_NAME pointer. A criterion of this type is created with OSSL_STORE_SEARCH_by_name(), and the actual subject name is retrieved with OSSL_STORE_SEARCH_get0_name(). Item "OSSL_STORE_SEARCH_BY_ISSUER_SERIAL" This criterion supports a search by exact match of both issuer name and serial number. The issuer name itself is a X509_NAME pointer, and the serial number is a \s-1ASN1_INTEGER\s0 pointer. A criterion of this type is created with OSSL_STORE_SEARCH_by_issuer_serial() and the actual issuer name and serial number are retrieved with \fBOSSL_STORE_SEARCH_get0_name() and OSSL_STORE_SEARCH_get0_serial(). Item "OSSL_STORE_SEARCH_BY_KEY_FINGERPRINT" This criterion supports a search by exact match of key fingerprint. The key fingerprint in itself is a string of bytes and its length, as well as the algorithm that was used to compute the fingerprint. The digest may be left unspecified (\s-1NULL\s0), and in that case, the loader has to decide on a default digest and compare fingerprints accordingly. A criterion of this type is created with OSSL_STORE_SEARCH_by_key_fingerprint() and the actual fingerprint and its length can be retrieved with \fBOSSL_STORE_SEARCH_get0_bytes(). The digest can be retrieved with OSSL_STORE_SEARCH_get0_digest(). Item "OSSL_STORE_SEARCH_BY_ALIAS" This criterion supports a search by match of an alias of some kind. The alias in itself is a simple C string. A criterion of this type is created with OSSL_STORE_SEARCH_by_alias() and the actual alias is retrieved with OSSL_STORE_SEARCH_get0_string(). Header "RETURN VALUES" \fBOSSL_STORE_SEARCH_by_name(), \fBOSSL_STORE_SEARCH_by_issuer_serial(), \fBOSSL_STORE_SEARCH_by_key_fingerprint(), and OSSL_STORE_SEARCH_by_alias() return a \s-1OSSL_STORE_SEARCH\s0 pointer on success, or \s-1NULL\s0 on failure.

\fBOSSL_STORE_SEARCH_get_type() returns the criterion type of the given \fB\s-1OSSL_STORE_SEARCH\s0. There is no error value.

\fBOSSL_STORE_SEARCH_get0_name() returns a X509_NAME pointer on success, or \s-1NULL\s0 when the given \s-1OSSL_STORE_SEARCH\s0 was of a different type.

\fBOSSL_STORE_SEARCH_get0_serial() returns a \s-1ASN1_INTEGER\s0 pointer on success, or \s-1NULL\s0 when the given \s-1OSSL_STORE_SEARCH\s0 was of a different type.

\fBOSSL_STORE_SEARCH_get0_bytes() returns a const unsigned char pointer and sets *length to the strings length on success, or \s-1NULL\s0 when the given \fB\s-1OSSL_STORE_SEARCH\s0 was of a different type.

\fBOSSL_STORE_SEARCH_get0_string() returns a const char pointer on success, or \s-1NULL\s0 when the given \s-1OSSL_STORE_SEARCH\s0 was of a different type.

\fBOSSL_STORE_SEARCH_get0_digest() returns a const \s-1EVP_MD\s0 pointer. \fB\s-1NULL\s0 is a valid value and means that the store loader default will be used when applicable.
