.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
These functions are used to specify search criteria to help search for specific
objects through other names than just the \s-1URI\s0 that's given to \fBOSSL_STORE_open()\fR.
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.
