                               OSSL_LIB_CTX *libctx, const char *propq);

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

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_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.
