DESCRIPTION
OSSL_CMP_ATAV is a short hand of OSSL_CRMF_ATTRIBUTETYPEANDVALUE,
defined in RFC 4211 Appendix B. It is typically used in CertRequest
structures, but also in CertReqTemplateContent structures for key
specifications.
OSSL_CMP_ATAV_create() creates a new OSSL_CMP_ATAV structure and fills
it in. It combines OSSL_CMP_ATAV_set0(3).
OSSL_CMP_ATAV_set0(3) sets the atav with an infoType of type and an
infoValue of value. The pointers type and value may be NULL, otherwise
they must not be freed up after the call because their ownership is
transferred to atav. The itav pointer must not be NULL.
OSSL_CMP_ATAV_get0_type() returns a direct pointer to the infoType in
the atav unless it is NULL.
OSSL_CMP_ATAV_get0_value() returns a direct pointer to the infoValue in
the atav as generic ASN1_TYPE pointer unless atav is NULL.
OSSL_CMP_ATAV_new_algId() creates a new OSSL_CMP_ATAV structure of type
algId and fills it in with a copy of the given alg.
OSSL_CMP_ATAV_get0_algId() returns a direct pointer to the algId
infoValue in the atav of type X509_ALGOR or NULL if atav is NULL or
does not contain an algId.
OSSL_CMP_ATAV_new_rsaKeyLen() creates a new OSSL_CMP_ATAV structure of
type rsaKeyLen and fills it in with the given len, which must be
positive.
OSSL_CMP_ATAV_get_rsaKeyLen() returns the RSA key length in rsaKeyLen
infoValue in the atav, -1 if atav is NULL or does not contain an
rsaKeyLen or cannot be parsed, or -2 if the value is less than 1 or is
greater than INT_MAX.
OSSL_CMP_ATAV_push1() pushes a copy of atav to the stack of
OSSL_CMP_ATAV pointed to by *sk_p. It creates a new stack if *sk_p
points to NULL.
OSSL_CMP_ATAV_free() deallocates atav. It is defined as a macro.
NOTES
CMP is defined in RFC 4210. CRMF is defined in RFC 4211.
RETURN VALUES
OSSL_CMP_ATAV_create(), OSSL_CMP_ATAV_new_algId(), and
OSSL_CMP_ATAV_new_rsaKeyLen() return a pointer to the ATAV structure on
success, or NULL on error.
OSSL_CMP_ATAV_set0(3) and OSSL_CMP_ATAV_free() do not return a value.
OSSL_CMP_ATAV_get0_type(), OSSL_CMP_ATAV_get0_value(), and
OSSL_CMP_ATAV_get0_algId() return the respective pointer or NULL if
their input is NULL.
OSSL_CMP_ATAV_get_rsaKeyLen() return a key length in bits or < 0 on
error.
OSSL_CMP_ATAV_push1() returns 1 on success, 0 on error.
