=head1 DESCRIPTION
|
|
|
|
OSSL_CRMF_MSG_set0_validity() sets the I<notBefore> and I<notAfter> fields
|
|
as validity constraints in the certTemplate of I<crm>.
|
|
Any of the I<notBefore> and I<notAfter> parameters may be NULL,
|
|
which means no constraint for the respective field.
|
|
On success ownership of I<notBefore> and I<notAfter> is transferred to I<crm>.
|
|
|
|
OSSL_CRMF_MSG_set_certReqId() sets I<rid> as the certReqId of I<crm>.
|
|
|
|
OSSL_CRMF_CERTTEMPLATE_fill() sets those fields of the certTemplate I<tmpl>
|
|
for which non-NULL values are provided: I<pubkey>, I<subject>, I<issuer>,
|
|
and/or I<serial>.
|
|
X.509 extensions may be set using OSSL_CRMF_MSG_set0_extensions().
|
|
On success the reference counter of the I<pubkey> (if given) is incremented,
|
|
while the I<subject>, I<issuer>, and I<serial> structures (if given) are copied.
|
|
|
|
OSSL_CRMF_MSG_set0_extensions() sets I<exts> as the extensions in the
|
|
certTemplate of I<crm>. Frees any pre-existing ones and consumes I<exts>.
|
|
|
|
OSSL_CRMF_MSG_push0_extension() pushes the X509 extension I<ext> to the
|
|
extensions in the certTemplate of I<crm>. Consumes I<ext>.
|
|
|
|
OSSL_CRMF_MSG_create_popo() creates and sets the Proof-of-Possession (POPO)
|
|
according to the method I<meth> in I<crm>.
|
|
The library context I<libctx> and property query string I<propq>,
|
|
may be NULL to select the defaults.
|
|
In case the method is OSSL_CRMF_POPO_SIGNATURE the POPO is calculated
|
|
using the private key I<pkey> and the digest method I<digest>,
|
|
where the I<digest> argument is ignored if I<pkey> is of a type (such as
|
|
Ed25519 and Ed448) that is implicitly associated with a digest algorithm.
|
|
|
|
I<meth> can be one of the following:
|
|
|
|
=over 8
|
|
|
|
=item * OSSL_CRMF_POPO_NONE - RFC 4211, section 4, POP field omitted.
|
|
CA/RA uses out-of-band method to verify POP. Note that servers may fail in this
|
|
case, resulting for instance in HTTP error code 500 (Internal error).
|
|
|
|
=item * OSSL_CRMF_POPO_RAVERIFIED - RFC 4211, section 4, explicit indication
|
|
that the RA has already verified the POP.
|
|
|
|
=item * OSSL_CRMF_POPO_SIGNATURE - RFC 4211, section 4.1, only case 3 supported
|
|
so far.
|
|
|
|
=item * OSSL_CRMF_POPO_KEYENC - RFC 4211, section 4.2, only indirect method
|
|
(subsequentMessage/enccert) supported,
|
|
challenge-response exchange (challengeResp) not yet supported.
|
|
|
|
=item * OSSL_CRMF_POPO_KEYAGREE - RFC 4211, section 4.3, not yet supported.

OSSL_CRMF_MSGS_verify_popo verifies the Proof-of-Possession of the request with
|
|
the given I<rid> in the list of I<reqs>. Optionally accepts RAVerified. It can
|
|
make use of the library context I<libctx> and property query string I<propq>.
