                                      OSSL_LIB_CTX *libctx, const char *propq);

        int OSSL_CRMF_MSGS_verify_popo(const OSSL_CRMF_MSGS *reqs,
                                       int rid, int acceptRAVerified,

DESCRIPTION

OSSL_CRMF_MSG_set0_validity() sets the notBefore and notAfter fields as validity constraints in the
certTemplate of crm. Any of the notBefore and notAfter parameters may be NULL, which means no constraint
for the respective field. On success ownership of notBefore and notAfter is transferred to crm.

OSSL_CRMF_MSG_set_certReqId() sets rid as the certReqId of crm.

OSSL_CRMF_CERTTEMPLATE_fill() sets those fields of the certTemplate tmpl for which non-NULL values are
provided: pubkey, subject, issuer, and/or serial. X.509 extensions may be set using
OSSL_CRMF_MSG_set0_extensions(). On success the reference counter of the pubkey (if given) is
incremented, while the subject, issuer, and serial structures (if given) are copied.

OSSL_CRMF_MSG_set0_extensions() sets exts as the extensions in the certTemplate of crm. Frees any pre-
existing ones and consumes exts.

OSSL_CRMF_MSG_push0_extension() pushes the X509 extension ext to the extensions in the certTemplate of
crm. Consumes ext.

OSSL_CRMF_MSG_create_popo() creates and sets the Proof-of-Possession (POPO) according to the method meth
in crm. The library context libctx and property query string 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 pkey and the
digest method digest, where the digest argument is ignored if pkey is of a type (such as Ed25519 and
Ed448) that is implicitly associated with a digest algorithm.

meth can be one of the following:

• 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).

• OSSL_CRMF_POPO_RAVERIFIED - RFC 4211, section 4, explicit indication that the RA has already
verified the POP.

• OSSL_CRMF_POPO_SIGNATURE - RFC 4211, section 4.1, only case 3 supported so far.

• OSSL_CRMF_POPO_KEYENC - RFC 4211, section 4.2, only indirect method
(subsequentMessage/enccert) supported, challenge-response exchange (challengeResp) not yet
supported.

• 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 rid in the list
of reqs. Optionally accepts RAVerified. It can make use of the library context libctx and property query
string propq.

RETURN VALUES

       All functions return 1 on success, 0 on error.

HISTORY

       The OpenSSL CRMF support was added in OpenSSL 3.0.
