=head1 SYNOPSIS
|
|
|
|
#include <openssl/cmp.h>
|
|
|
|
OSSL_CMP_ITAV *OSSL_CMP_ITAV_create(ASN1_OBJECT *type, ASN1_TYPE *value);
|
|
void OSSL_CMP_ITAV_set0(OSSL_CMP_ITAV *itav, ASN1_OBJECT *type,
|
|
ASN1_TYPE *value);
|
|
ASN1_OBJECT *OSSL_CMP_ITAV_get0_type(const OSSL_CMP_ITAV *itav);
|
|
ASN1_TYPE *OSSL_CMP_ITAV_get0_value(const OSSL_CMP_ITAV *itav);
|
|
int OSSL_CMP_ITAV_push0_stack_item(STACK_OF(OSSL_CMP_ITAV) **itav_sk_p,
|
|
OSSL_CMP_ITAV *itav);
|
|
|
|
=head1 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 B<OSSL_CMP_ITAV> structure and fills it in.
|
|
It combines OSSL_CMP_ITAV_new() and OSSL_CMP_ITAV_set0().
|
|
|
|
OSSL_CMP_ITAV_set0() sets the I<itav> with an infoType of I<type> and an
|
|
infoValue of I<value>. This function uses the pointers I<type> and I<value>
|
|
internally, so they must B<not> be freed up after the call.
|
|
|
|
OSSL_CMP_ITAV_get0_type() returns a direct pointer to the infoType in the
|
|
I<itav>.
|
|
|
|
OSSL_CMP_ITAV_get0_value() returns a direct pointer to the infoValue in
|
|
the I<itav> as generic B<ASN1_TYPE> pointer.
|
|
|
|
OSSL_CMP_ITAV_push0_stack_item() pushes I<itav> to the stack pointed to
|
|
by I<*itav_sk_p>. It creates a new stack if I<*itav_sk_p> points to NULL.
|
|
|
|
=head1 NOTES
|
|
|
|
CMP is defined in RFC 4210 (and CRMF in RFC 4211).
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
OSSL_CMP_ITAV_create() returns a pointer to the ITAV structure on success,
|
|
or NULL on error.
|
|
|
|
OSSL_CMP_ITAV_set0() 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() returns 1 on success, 0 on error.
|
|
|
|
=head1 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 B<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 */
