=head1 DESCRIPTION

This is the internal API for creating various CMP PKIMESSAGES.
All functions are based on L<ossl_cmp_msg_create(3)>.
The allocate a new message, fill it with the relevant data derived from
the given B<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 I<bodytype>.
The CRMF message to use may be given explicitly via a non-NULL I<crm> argument,
otherwise it is created from the information in the I<ctx>.

Available CMP certificate request PKIMessage I<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 I<bodytype>,
with the given I<certReqId> and I<si> values and optionally with I<cert>,
I<chain>, and I<caPubs>. The I<cert>, I<chain>, and I<caPubs> arguments
are not consumed if present but their internal reference counter is increased.
The I<encryption_recip> is currently unsupported.
The function does not protect the message if the B<status> value in I<si>
is B<rejected> and I<unprotectedErrors> is nonzero.

Available CMP certificate response PKIMessage I<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

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 I<si> and I<cid>.
It does not protect the message if the B<status> value in I<si> is B<rejected>
and I<unprotectedErrors> is nonzero.

ossl_cmp_certConf_new() creates a Certificate Confirmation message for the last
received certificate with the given I<certReqId>.
The PKIStatus defaults to B<accepted> if the I<fail_info> bit field is 0.
Otherwise it is taken as the failInfo of the PKIStatusInfo, PKIStatus is
set to B<rejected>, and I<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
I<crid>.

ossl_cmp_pollRep_new() creates a Polling Response message with certReqId set to
I<crid> and pollAfter to I<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
I<si>, I<errorCode>, and optional I<details>.
If I<errorCode> is positive and in the range of an OpenSSL error code,
the library and reason strings are included in the B<errorDetails> field.
If given, the I<details> are added to the contents of the B<errorDetails> field.
The function does not protect the message if I<unprotectedErrors> is nonzero.

=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 HISTORY

The OpenSSL CMP support was added in OpenSSL 3.0.
