Also includes CRMF (RFC 4211) and HTTP transfer (RFC 6712)
CMP and CRMF API is added to libcrypto, and the "cmp" app to the openssl CLI.
Adds extensive man pages and tests. Integration into build scripts.

|
=head1 DESCRIPTION
|
|
|
|
OSSL_CRMF_MSG_set_validity() sets B<from> as notBefore and B<to> as notAfter
|
|
as the validity in the certTemplate of B<crm>.
|
|
|
|
OSSL_CRMF_MSG_set_certReqId() sets B<rid> as the certReqId of B<crm>.
|
|
|
|
OSSL_CRMF_CERTTEMPLATE_fill() sets those fields of the certTemplate B<tmpl>
|
|
for which non-NULL values are provided: B<pubkey>, B<subject>, B<issuer>,
|
|
and/or B<serial>.
|
|
On success the reference counter of the B<pubkey> (if given) is incremented,
|
|
while the B<subject>, B<issuer>, and B<serial> structures (if given) are copied.
|
|
|
|
OSSL_CRMF_MSG_set0_extensions() sets B<exts> as the extensions in the
|
|
certTemplate of B<crm>. Frees any pre-existing ones and consumes B<exts>.
|
|
|
|
OSSL_CRMF_MSG_push0_extension() pushes the X509 extension B<ext> to the
|
|
extensions in the certTemplate of B<crm>. Consumes B<ext>.
|
|
|
|
OSSL_CRMF_MSG_create_popo() creates and sets the Proof-of-Possession (POPO)
|
|
according to the method B<ppmtd> in B<crm>.
|
|
In case the method is OSSL_CRMF_POPO_SIGNATURE the POPO is calculated
|
|
using the private B<pkey> and the digest algorithm NID B<dgst>.
|
|
|
|
B<ppmtd> 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 B<rid> in the list of B<reqs>. Optionally accepts RAVerified.

|
|
=head1 RETURN VALUES

All functions return 1 on success, 0 on error.
