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. =back 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. =head1 SEE ALSO RFC 4211 =head1 HISTORY The OpenSSL CRMF support was added in OpenSSL 3.0. =head1 COPYRIGHT Copyright 2007-2019 The OpenSSL Project Authors.
