=head1 DESCRIPTION
These routines set and get the holder identity of an X509 attribute certificate.
X509_ACERT_set0_holder_entityName() sets the identity as a B<GENERAL_NAME>
I<name>, X509_ACERT_set0_holder_baseCertId() sets the identity based on the
issuer and serial number of a certificate detailed in I<isss> and
X509_ACERT_set0_holder_digest() sets the holder entity based on digest
information I<dinfo>. Although RFC 5755 section 4.2.2 recommends that only
one of the above methods be used to set the holder identity for a given
attribute certificate I<x>, setting multiple methods at the same time is
possible. It is up to the application to handle cases when conflicting
identity information is specified using different methods.
Pointers to the internal structures describing the holder identity of
attribute certificate I<x> can be retrieved with
X509_ACERT_get0_holder_entityName(), X509_ACERT_get0_holder_baseCertId(), and
X509_ACERT_get0_holder_digest().
A B<OSSL_ISSUER_SERIAL> object holds the subject name and UID of a certificate
issuer and a certificate's serial number. OSSL_ISSUER_SERIAL_set1_issuer(),
OSSL_ISSUER_SERIAL_set1_issuerUID(), and OSSL_ISSUER_SERIAL_set1_serial()
respectively copy these values into the B<OSSL_ISSUER_SERIAL> structure.
The application is responsible for freeing its own copy of these values after
use. OSSL_ISSUER_SERIAL_get0_issuer(), OSSL_ISSUER_SERIAL_get0_issuerUID(),
and OSSL_ISSUER_SERIAL_get0_serial() return pointers to these values in the object.
An B<OSSL_OBJECT_DIGEST_INFO> object holds a digest of data to identify the
attribute certificate holder. OSSL_OBJECT_DIGEST_INFO_set1_digest() sets the
digest information of the object. The type of I<digest> information is given
by I<digestedObjectType> and can be one of:
=over 4
=item OSSL_OBJECT_DIGEST_INFO_PUBLIC_KEY
Hash of a public key
=item OSSL_OBJECT_DIGEST_INFO_PUBLIC_KEY_CERT
Hash of a public key certificate
=item OSSL_OBJECT_DIGEST_INFO_OTHER
Hash of another object. See NOTES below.
=back
I<digestAlgorithm> indicates the algorithm used to compute I<digest>.
=head1 RETURN VALUES
All I<set0>/I<set1> routines return 1 for success and 0 for failure.
All I<get0> functions return a pointer to the object's inner structure. These
pointers must not be freed after use.
=head1 NOTES
Although the value of B<OSSL_OBJECT_DIGEST_INFO_OTHER> is defined in RFC 5755,
its use is prohibited for conformant attribute certificates.
=head1 HISTORY
These functions were added in OpenSSL 3.4.
