STACK_OF(ASN1_UTF8STRING) **out);
DESCRIPTION
ITAV is short for InfoTypeAndValue. This type is defined in RFC 4210
section 5.3.19 and Appendix F. It is used at various places in CMP
messages, e.g., in the generalInfo PKIHeader field, to hold a key-value
pair.
OSSL_CMP_ITAV_create() creates a new OSSL_CMP_ITAV structure and fills
it in. It combines OSSL_CMP_ITAV_set0(3).
OSSL_CMP_ITAV_set0(3) sets the itav with an infoType of type and an
infoValue of value. This function uses the pointers type and value
internally, so they must not be freed up after the call.
OSSL_CMP_ITAV_get0_type() returns a direct pointer to the infoType in
the itav.
OSSL_CMP_ITAV_get0_value() returns a direct pointer to the infoValue in
the itav as generic ASN1_TYPE pointer.
OSSL_CMP_ITAV_push0_stack_item() pushes itav to the stack pointed to by
*itav_sk_p. It creates a new stack if *itav_sk_p points to NULL.
OSSL_CMP_ITAV_new0_certProfile() creates a new OSSL_CMP_ITAV structure
of type certProfile that includes the optionally given list of profile
names. On success, ownership of the list is with the new OSSL_CMP_ITAV
structure.
OSSL_CMP_ITAV_get0_certProfile() on success assigns to *out an internal
pointer to the list of certificate profile names contained in the
infoValue field of itav. The pointer may be NULL if no profile name is
included. It is an error if the infoType of itav is not certProfile.
NOTES
CMP is defined in RFC 4210 and RFC 9480 (and CRMF in RFC 4211).
OIDs to use as types in OSSL_CMP_ITAV can be found at
<https://datatracker.ietf.org/doc/html/rfc9480#section-4.2.2>. The
respective OpenSSL NIDs, such as NID_id_it_certProfile, are defined in
the <openssl/obj_mac.h> header file.
RETURN VALUES
OSSL_CMP_ITAV_create() and OSSL_CMP_ITAV_new0_certProfile() return a
pointer to an ITAV structure on success, or NULL on error.
OSSL_CMP_ITAV_set0(3) does not return a value.
OSSL_CMP_ITAV_get0_type() and OSSL_CMP_ITAV_get0_value() return the
respective pointer or NULL if their input is NULL.
OSSL_CMP_ITAV_push0_stack_item() and OSSL_CMP_ITAV_get0_certProfile()
return 1 on success, 0 on error.
EXAMPLES
The following code creates and sets a structure representing a generic
InfoTypeAndValue sequence, using an OID created from text as type, and
an integer as value. Afterwards, it is pushed to the OSSL_CMP_CTX to be
later included in the requests' PKIHeader's genInfo field.
ASN1_OBJECT *type = OBJ_txt2obj("1.2.3.4.5", 1);
if (type == NULL) ...
ASN1_INTEGER *asn1int = ASN1_INTEGER_new();
if (asn1int == NULL || !ASN1_INTEGER_set(asn1int, 12345)) ...
ASN1_TYPE *val = ASN1_TYPE_new();
if (val == NULL) ...
ASN1_TYPE_set(val, V_ASN1_INTEGER, asn1int);
OSSL_CMP_ITAV *itav = OSSL_CMP_ITAV_create(type, val);
if (itav == NULL) ...
if (!OSSL_CMP_CTX_push0_geninfo_ITAV(ctx, itav)) {
OSSL_CMP_ITAV_free(itav); /* also frees type and val */
...
}
...
OSSL_CMP_CTX_free(ctx); /* also frees itav */
