DESCRIPTION
ITAV is short for InfoTypeAndValue.
OSSL_CMP_ITAV_new_caCerts() creates an OSSL_CMP_ITAV structure of type
caCerts and fills it with a copy of the provided list of certificates.
The caCerts argument may be NULL or contain any number of certificates.
OSSL_CMP_ITAV_get0_caCerts() requires that itav has type caCerts. It
assigns NULL to *out if there are no CA certificates in itav, otherwise
the internal pointer of type STACK_OF(X509) with the certificates
present.
OSSL_CMP_ITAV_new_rootCaCert() creates a new OSSL_CMP_ITAV structure of
type rootCaCert that includes the optionally given certificate.
OSSL_CMP_ITAV_get0_rootCaCert() requires that itav has type rootCaCert.
It assigns NULL to *out if no certificate is included in itav, otherwise
the internal pointer to the certificate contained in the infoValue
field.
OSSL_CMP_ITAV_new_rootCaKeyUpdate() creates a new OSSL_CMP_ITAV
structure of type rootCaKeyUpdate that includes an
RootCaKeyUpdateContent structure with the optional newWithNew,
newWithOld, and oldWithNew certificates. An RootCaKeyUpdateContent
structure is included only if newWithNew is not NULL.
OSSL_CMP_ITAV_get0_rootCaKeyUpdate() requires that itav has infoType
rootCaKeyUpdate. If an update of a root CA certificate is included, it
assigns to *newWithNew the internal pointer to the certificate contained
in the newWithNew infoValue sub-field of itav. If newWithOld is not
NULL, it assigns to *newWithOld the internal pointer to the certificate
contained in the newWithOld infoValue sub-field of itav. If oldWithNew
is not NULL, it assigns to *oldWithNew the internal pointer to the
certificate contained in the oldWithNew infoValue sub-field of itav.
Each of these pointers will be set to NULL if no root CA certificate
update is present or the respective sub-field is not included.
OSSL_CMP_CRLSTATUS_new1() allocates a new OSSL_CMP_CRLSTATUS structure
that contains either a copy of the distribution point name dpn or a copy
of the certificate issuer issuer, while giving both is an error. If
given, a copy of the CRL issuance time thisUpdate is also included.
OSSL_CMP_CRLSTATUS_create() is a high-level variant of
OSSL_CMP_CRLSTATUS_new1(). It fills the thisUpdate field with a copy of
the thisUpdate field of crl if present. It fills the CRLSource field
with a copy of the first data item found using the crl and/or cert
parameters as follows. Any available distribution point name is
preferred over issuer names. Data from cert, if present, is preferred
over data from crl. If no distribution point names are available,
candidate issuer names are taken from following sources, as far as
present:
the list of distribution points in the first cRLDistributionPoints
extension of cert,
the issuer field of the authority key identifier of cert,
the issuer DN of cert,
the issuer field of the authority key identifier of crl, and
the issuer DN of crl.
If <only_DN> is set, a candidate issuer name of type GENERAL_NAMES is
accepted only if it contains exactly one general name of type
directoryName.
OSSL_CMP_CRLSTATUS_get0() reads the fields of crlstatus and assigns them
to *dpn, *issuer, and *thisUpdate. *thisUpdate is assigned only if the
thisUpdate argument is not NULL. Depending on the choice present,
either *dpn or *issuer will be NULL. *thisUpdate can also be NULL if
the field is not present.
OSSL_CMP_ITAV_new0_crlStatusList() creates a new OSSL_CMP_ITAV structure
of type crlStatusList that includes the optionally given list of CRL
status data, each of which is of type OSSL_CMP_CRLSTATUS.
OSSL_CMP_ITAV_get0_crlStatusList() on success assigns to *out an
internal pointer to the list of CRL status data in the infoValue field
of itav. The pointer may be NULL if no CRL status data is included. It
is an error if the infoType of itav is not crlStatusList.
OSSL_CMP_ITAV_new_crls() creates a new OSSL_CMP_ITAV structure of type
crls including an empty list of CRLs if the crl argument is NULL or
including a singleton list a with copy of the provided CRL otherwise.
OSSL_CMP_ITAV_get0_crls() on success assigns to *out an internal pointer
to the list of CRLs contained in the infoValue field of itav. The
pointer may be NULL if no CRL is included. It is an error if the
infoType of itav is not crls.
OSSL_CMP_ITAV_new0_certReqTemplate() creates an OSSL_CMP_ITAV structure
of type certReqTemplate. If certTemplate is NULL then also keySpec must
be NULL, and the resulting ITAV can be used in a genm message to obtain
the requirements a PKI has on the certificate template used to request
certificates, or in a genp message stating that there are no such
requirements. Otherwise the resulting ITAV includes a
CertReqTemplateValue structure with certTemplate of type
OSSL_CRMF_CERTTEMPLATE and an optional list of key specifications
keySpec, each being of type OSSL_CMP_ATAV, and the resulting ATAV can be
used in a genp message to provide requirements.
OSSL_CMP_ITAV_get1_certReqTemplate() requires that itav has type
certReqTemplate. If assigns NULL to *certTemplate if no
OSSL_CRMF_CERTTEMPLATE structure with a certificate template value is in
itav, otherwise a copy of the certTemplate field value. If keySpec is
not NULL, it is assigned NULL if the structure is not present in itav or
the keySpec field is absent. Otherwise, the function checks that all
elements of keySpec field are of type algId or rsaKeyLen and assigns to
*keySpec a copy of the keySpec field.
NOTES
CMP is defined in RFC 9810.
