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. .SS "Types" .IX Subsection "Types" \&\fB\s-1OSSL_STORE_SEARCH\s0\fR 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()\fR. .PP The calling application owns the allocation of an \fB\s-1OSSL_STORE_SEARCH\s0\fR at all times, and should therefore be careful not to deallocate it before \&\fBOSSL_STORE_close()\fR has been called for the \s-1OSSL_STORE\s0 context it was given to. .SS "Application Functions" .IX Subsection "Application Functions" \&\fBOSSL_STORE_SEARCH_by_name()\fR, \&\fBOSSL_STORE_SEARCH_by_issuer_serial()\fR, \&\fBOSSL_STORE_SEARCH_by_key_fingerprint()\fR, and \fBOSSL_STORE_SEARCH_by_alias()\fR are used to create an \fB\s-1OSSL_STORE_SEARCH\s0\fR 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\fR. .PP \&\fBOSSL_STORE_SEARCH_free()\fR is used to free the \fB\s-1OSSL_STORE_SEARCH\s0\fR. .SS "Loader Functions" .IX Subsection "Loader Functions" \&\fBOSSL_STORE_SEARCH_get_type()\fR returns the criterion type for the given \&\fB\s-1OSSL_STORE_SEARCH\s0\fR. .PP \&\fBOSSL_STORE_SEARCH_get0_name()\fR, \fBOSSL_STORE_SEARCH_get0_serial()\fR, \&\fBOSSL_STORE_SEARCH_get0_bytes()\fR, \fBOSSL_STORE_SEARCH_get0_string()\fR, and \fBOSSL_STORE_SEARCH_get0_digest()\fR are used to retrieve different data from a \fB\s-1OSSL_STORE_SEARCH\s0\fR, as available for each type. For more information, see \*(L"\s-1SUPPORTED CRITERION TYPES\*(R"\s0 below. .SH "SUPPORTED CRITERION TYPES" .IX Header "SUPPORTED CRITERION TYPES" Currently supported criterion types are: .IP "\s-1OSSL_STORE_SEARCH_BY_NAME\s0" 4 .IX Item "OSSL_STORE_SEARCH_BY_NAME" This criterion supports a search by exact match of subject name. The subject name itself is a \fBX509_NAME\fR pointer. A criterion of this type is created with \fBOSSL_STORE_SEARCH_by_name()\fR, and the actual subject name is retrieved with \fBOSSL_STORE_SEARCH_get0_name()\fR. .IP "\s-1OSSL_STORE_SEARCH_BY_ISSUER_SERIAL\s0" 4 .IX 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 \fBX509_NAME\fR pointer, and the serial number is a \fB\s-1ASN1_INTEGER\s0\fR pointer. A criterion of this type is created with \fBOSSL_STORE_SEARCH_by_issuer_serial()\fR and the actual issuer name and serial number are retrieved with \&\fBOSSL_STORE_SEARCH_get0_name()\fR and \fBOSSL_STORE_SEARCH_get0_serial()\fR. .IP "\s-1OSSL_STORE_SEARCH_BY_KEY_FINGERPRINT\s0" 4 .IX 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 \fBOSSL_STORE_SEARCH_by_key_fingerprint()\fR and the actual fingerprint and its length can be retrieved with \&\fBOSSL_STORE_SEARCH_get0_bytes()\fR. The digest can be retrieved with \fBOSSL_STORE_SEARCH_get0_digest()\fR. .IP "\s-1OSSL_STORE_SEARCH_BY_ALIAS\s0" 4 .IX 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 \fBOSSL_STORE_SEARCH_by_alias()\fR and the actual alias is retrieved with \fBOSSL_STORE_SEARCH_get0_string()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOSSL_STORE_SEARCH_by_name()\fR, \&\fBOSSL_STORE_SEARCH_by_issuer_serial()\fR, \&\fBOSSL_STORE_SEARCH_by_key_fingerprint()\fR, and \fBOSSL_STORE_SEARCH_by_alias()\fR return a \fB\s-1OSSL_STORE_SEARCH\s0\fR pointer on success, or \fB\s-1NULL\s0\fR on failure. .PP \&\fBOSSL_STORE_SEARCH_get_type()\fR returns the criterion type of the given \&\fB\s-1OSSL_STORE_SEARCH\s0\fR. There is no error value. .PP \&\fBOSSL_STORE_SEARCH_get0_name()\fR returns a \fBX509_NAME\fR pointer on success, or \fB\s-1NULL\s0\fR when the given \fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type. .PP \&\fBOSSL_STORE_SEARCH_get0_serial()\fR returns a \fB\s-1ASN1_INTEGER\s0\fR pointer on success, or \fB\s-1NULL\s0\fR when the given \fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type. .PP \&\fBOSSL_STORE_SEARCH_get0_bytes()\fR returns a \fBconst unsigned char\fR pointer and sets \fB*length\fR to the strings length on success, or \fB\s-1NULL\s0\fR when the given \&\fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type. .PP \&\fBOSSL_STORE_SEARCH_get0_string()\fR returns a \fBconst char\fR pointer on success, or \fB\s-1NULL\s0\fR when the given \fB\s-1OSSL_STORE_SEARCH\s0\fR was of a different type. .PP \&\fBOSSL_STORE_SEARCH_get0_digest()\fR returns a \fBconst \s-1EVP_MD\s0\fR pointer. \&\fB\s-1NULL\s0\fR is a valid value and means that the store loader default will be used when applicable. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBossl_store\fR\|(7), \fBOSSL_STORE_supports_search\fR\|(3), \fBOSSL_STORE_find\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fB\s-1OSSL_STORE_SEARCH\s0\fR, \&\fBOSSL_STORE_SEARCH_by_name()\fR, \&\fBOSSL_STORE_SEARCH_by_issuer_serial()\fR, \&\fBOSSL_STORE_SEARCH_by_key_fingerprint()\fR, \&\fBOSSL_STORE_SEARCH_by_alias()\fR, \&\fBOSSL_STORE_SEARCH_free()\fR, \&\fBOSSL_STORE_SEARCH_get_type()\fR, \&\fBOSSL_STORE_SEARCH_get0_name()\fR, \&\fBOSSL_STORE_SEARCH_get0_serial()\fR, \&\fBOSSL_STORE_SEARCH_get0_bytes()\fR, and \fBOSSL_STORE_SEARCH_get0_string()\fR were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2018 The OpenSSL Project Authors.
