=head1 DESCRIPTION
|
|
|
|
B<OSSL_CMP_ATAV> is a short hand of B<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 B<OSSL_CMP_ATAV> structure and fills it in.
|
|
It combines OSSL_CMP_ATAV_new() and OSSL_CMP_ATAV_set0().
|
|
|
|
OSSL_CMP_ATAV_set0() sets the I<atav> with an infoType of I<type> and an
|
|
infoValue of I<value>.
|
|
The pointers I<type> and I<value> may be NULL, otherwise
|
|
they must B<not> be freed up after the call because their ownership
|
|
is transferred to I<atav>. The I<itav> pointer must not be NULL.
|
|
|
|
OSSL_CMP_ATAV_get0_type() returns a direct pointer to the infoType
|
|
in the I<atav> unless it is NULL.
|
|
|
|
OSSL_CMP_ATAV_get0_value() returns a direct pointer to the infoValue
|
|
in the I<atav> as generic B<ASN1_TYPE> pointer unless I<atav> is NULL.
|
|
|
|
OSSL_CMP_ATAV_new_algId() creates a new B<OSSL_CMP_ATAV> structure of type
|
|
B<algId> and fills it in with a copy of the given I<alg>.
|
|
|
|
OSSL_CMP_ATAV_get0_algId() returns
|
|
a direct pointer to the algId infoValue in the I<atav> of type B<X509_ALGOR>
|
|
or NULL if I<atav> is NULL or does not contain an algId.
|
|
|
|
OSSL_CMP_ATAV_new_rsaKeyLen() creates a new B<OSSL_CMP_ATAV> structure of type
|
|
B<rsaKeyLen> and fills it in with the given I<len>, which must be positive.
|
|
|
|
OSSL_CMP_ATAV_get_rsaKeyLen() returns
|
|
the RSA key length in rsaKeyLen infoValue in the I<atav>,
|
|
-1 if I<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 I<atav> to the stack of B<OSSL_CMP_ATAV>
|
|
pointed to by I<*sk_p>. It creates a new stack if I<*sk_p> points to NULL.
|
|
|
|
OSSL_CMP_ATAV_free() deallocates I<atav>. It is defined as a macro.
|
|
|
|
=head1 NOTES
|
|
|
|
CMP is defined in RFC 4210. CRMF is defined in RFC 4211.
|
|
|
|
=head1 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() 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.
