168 .IX Header "DESCRIPTION"
169 These functions are used to specify search criteria to help search for specific
170 objects through other names than just the \s-1URI\s0 that's given to \fIOSSL_STORE_open()\fR.
171 For example, this can be useful for an application that has received a \s-1URI\s0
172 and then wants to add on search criteria in a uniform and supported manner.
174 .IX Subsection "Types"
175 \&\fB\s-1OSSL_STORE_SEARCH\s0\fR is an opaque type that holds the constructed search
176 criterion, and that can be given to an \s-1OSSL_STORE\s0 context with
177 \&\fIOSSL_STORE_find()\fR.
179 The calling application owns the allocation of an \fB\s-1OSSL_STORE_SEARCH\s0\fR at all
180 times, and should therefore be careful not to deallocate it before
181 \&\fIOSSL_STORE_close()\fR has been called for the \s-1OSSL_STORE\s0 context it was given

208 .SH "SUPPORTED CRITERION TYPES"
209 .IX Header "SUPPORTED CRITERION TYPES"
210 Currently supported criterion types are:
211 .IP "\s-1OSSL_STORE_SEARCH_BY_NAME\s0" 4
212 .IX Item "OSSL_STORE_SEARCH_BY_NAME"
213 This criterion supports a search by exact match of subject name.
214 The subject name itself is a \fBX509_NAME\fR pointer.
215 A criterion of this type is created with \fIOSSL_STORE_SEARCH_by_name()\fR,
216 and the actual subject name is retrieved with \fIOSSL_STORE_SEARCH_get0_name()\fR.
217 .IP "\s-1OSSL_STORE_SEARCH_BY_ISSUER_SERIAL\s0" 4
218 .IX Item "OSSL_STORE_SEARCH_BY_ISSUER_SERIAL"
219 This criterion supports a search by exact match of both issuer name and serial
221 The issuer name itself is a \fBX509_NAME\fR pointer, and the serial number is
222 a \fB\s-1ASN1_INTEGER\s0\fR pointer.
223 A criterion of this type is created with \fIOSSL_STORE_SEARCH_by_issuer_serial()\fR
224 and the actual issuer name and serial number are retrieved with
225 \&\fIOSSL_STORE_SEARCH_get0_name()\fR and \fIOSSL_STORE_SEARCH_get0_serial()\fR.
226 .IP "\s-1OSSL_STORE_SEARCH_BY_KEY_FINGERPRINT\s0" 4
227 .IX Item "OSSL_STORE_SEARCH_BY_KEY_FINGERPRINT"
228 This criterion supports a search by exact match of key fingerprint.
229 The key fingerprint in itself is a string of bytes and its length, as
230 well as the algorithm that was used to compute the fingerprint.
231 The digest may be left unspecified (\s-1NULL\s0), and in that case, the
232 loader has to decide on a default digest and compare fingerprints
234 A criterion of this type is created with \fIOSSL_STORE_SEARCH_by_key_fingerprint()\fR
235 and the actual fingerprint and its length can be retrieved with
236 \&\fIOSSL_STORE_SEARCH_get0_bytes()\fR.
237 The digest can be retrieved with \fIOSSL_STORE_SEARCH_get0_digest()\fR.
238 .IP "\s-1OSSL_STORE_SEARCH_BY_ALIAS\s0" 4
239 .IX Item "OSSL_STORE_SEARCH_BY_ALIAS"
240 This criterion supports a search by match of an alias of some kind.
241 The alias in itself is a simple C string.
242 A criterion of this type is created with \fIOSSL_STORE_SEARCH_by_alias()\fR
243 and the actual alias is retrieved with \fIOSSL_STORE_SEARCH_get0_string()\fR.
245 .IX Header "RETURN VALUES"
246 \&\fIOSSL_STORE_SEARCH_by_name()\fR,
247 \&\fIOSSL_STORE_SEARCH_by_issuer_serial()\fR,
248 \&\fIOSSL_STORE_SEARCH_by_key_fingerprint()\fR,
249 and \fIOSSL_STORE_SEARCH_by_alias()\fR
250 return a \fB\s-1OSSL_STORE_SEARCH\s0\fR pointer on success, or \fB\s-1NULL\s0\fR on failure.
252 \&\fIOSSL_STORE_SEARCH_get_type()\fR returns the criterion type of the given
253 \&\fB\s-1OSSL_STORE_SEARCH\s0\fR.
254 There is no error value.
256 \&\fIOSSL_STORE_SEARCH_get0_name()\fR returns a \fBX509_NAME\fR pointer on success,
257 or \fB\s-1NULL\s0\fR when the given \fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type.
259 \&\fIOSSL_STORE_SEARCH_get0_serial()\fR returns a \fB\s-1ASN1_INTEGER\s0\fR pointer on success,
260 or \fB\s-1NULL\s0\fR when the given \fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type.
262 \&\fIOSSL_STORE_SEARCH_get0_bytes()\fR returns a \fBconst unsigned char\fR pointer and
263 sets \fB*length\fR to the strings length on success, or \fB\s-1NULL\s0\fR when the given
264 \&\fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type.
266 \&\fIOSSL_STORE_SEARCH_get0_string()\fR returns a \fBconst char\fR pointer on success,
267 or \fB\s-1NULL\s0\fR when the given \fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type.
269 \&\fIOSSL_STORE_SEARCH_get0_digest()\fR returns a \fBconst \s-1EVP_MD\s0\fR pointer.
270 \&\fB\s-1NULL\s0\fR is a valid value and means that the store loader default will
271 be used when applicable.
