=head1 DESCRIPTION

This is the API for creating various CMP PKIMESSAGES. The
functions allocate a new message, fill it with the relevant data derived from
the given OSSL_CMP_CTX, and create the applicable protection.

ossl_cmp_certreq_new() creates a PKIMessage for requesting a certificate,
which can be either of IR/CR/KUR/P10CR, depending on the given B<bodytype>.
The CRMF message to use may be given via the B<crm> argument;
else (if B<crm> is NULL) it is created from the information in the B<ctx>.

Available CMP certificate request PKIMessage B<bodytype>s are:

=over 4

=item * B<OSSL_CMP_PKIBODY_IR>    - Initialization Request

=item * B<OSSL_CMP_PKIBODY_CR>    - Certification Request

=item * B<OSSL_CMP_PKIBODY_P10CR> - PKCS#10 Certification Request

=item * B<OSSL_CMP_PKIBODY_KUR>   - Key Update Request

=back

ossl_cmp_certrep_new() creates a PKIMessage for certificate response, which can
be either of IP/CP/KUP, depending on the given B<bodytype>.

Available CMP certificate response PKIMessage B<bodytype>s are:

=over 4

=item * B<OSSL_CMP_PKIBODY_IP>    - Initialization Response

=item * B<OSSL_CMP_PKIBODY_CP>    - Certification Response

=item * B<OSSL_CMP_PKIBODY_KUP>   - Key Update Response

=back

The list of all CMP PKIMessage B<bodytype>s is:

ossl_cmp_rr_new() creates a Revocation Request message from the
information set via OSSL_CMP_CTX_set1_oldClCert().

ossl_cmp_rp_new() creates a Revocation Response message with status set to
B<si> and CertID set to B<cid>. Consumes B<cid>.
Accepts unprotected errors if B<uprot_err> != 0.

ossl_cmp_certConf_new() creates a Certificate Confirmation message for the last
received certificate. PKIStatus defaults to B<accepted> if the B<fail_info> bit
field is 0. Else it is taken as the failInfo of the PKIStatusInfo, PKIStatus is
set to B<rejected>, and B<text> is copied to statusString unless it is NULL.

ossl_cmp_pkiconf_new() creates a PKI Confirmation message.

ossl_cmp_pollReq_new() creates a Polling Request message with certReqId set to
B<crid>.

ossl_cmp_pollRep_new() creates a Polling Response message with certReqId set to
B<crid> and pollAfter to B<poll_after>.

ossl_cmp_genm_new() creates a new General Message with an empty ITAV stack.

ossl_cmp_genp_new() creates a new General Response with an empty ITAV stack.

ossl_cmp_error_new() creates a new Error Message with the given contents,
copying B<si> and B<errorDetails>.

=head1 NOTES

CMP is specified in RFC 4210 (and CRMF in RFC 4211).

=head1 RETURN VALUES

All of the functions return a new OSSL_CMP_MSG structure containing
the generated message on success, or NULL on error.

=head1 SEE ALSO

=head1 HISTORY

The OpenSSL CMP support was added in OpenSSL 3.0.
