\fBX509_ACERT_set0_holder_entityName() sets the identity as a GENERAL_NAME \fIname, X509_ACERT_set0_holder_baseCertId() sets the identity based on the issuer and serial number of a certificate detailed in isss and \fBX509_ACERT_set0_holder_digest() sets the holder entity based on digest information 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 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 x can be retrieved with \fBX509_ACERT_get0_holder_entityName(), X509_ACERT_get0_holder_baseCertId(), and \fBX509_ACERT_get0_holder_digest().

A 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(), \fBOSSL_ISSUER_SERIAL_set1_issuerUID(), and OSSL_ISSUER_SERIAL_set1_serial() respectively copy these values into the 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 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 digest information is given by digestedObjectType and can be one of:

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.

\fIdigestAlgorithm indicates the algorithm used to compute digest.

Header "RETURN VALUES" All set0/set1 routines return 1 for success and 0 for failure. All get0 functions return a pointer to the object's inner structure. These pointers must not be freed after use. Header "NOTES" Although the value of OSSL_OBJECT_DIGEST_INFO_OTHER is defined in RFC 5755, its use is prohibited for conformant attribute certificates.
