If \fIctx\fR does not contain a transaction ID, a fresh one is created before. The message gets re-protected (if protecting requests is required). .PP \&\fBOSSL_CMP_MSG_update_recipNonce()\fR updates the recipNonce field in the header of the given message according to the CMP_CTX. The message gets re-protected (if protecting requests is required). .PP \&\fBOSSL_CMP_CTX_setup_CRM()\fR creates a CRMF certificate request message from various information provided in the CMP context argument \fIctx\fR for inclusion in a CMP request message based on details contained in \fIctx\fR. The \fIrid\fR argument defines the request identifier to use, which typically is 0. .PP The subject DN included in the certificate template is the first available value of these: .IP "any subject name in \fIctx\fR set via \fBOSSL_CMP_CTX_set1_subjectName\fR\|(3) \- if it is the NULL-DN (i.e., any empty sequence of RDNs), no subject is included," 4 .IX Item "any subject name in ctx set via OSSL_CMP_CTX_set1_subjectName - if it is the NULL-DN (i.e., any empty sequence of RDNs), no subject is included," .PD 0 .IP "the subject field of any PKCS#10 CSR set in \fIctx\fR via \fBOSSL_CMP_CTX_set1_p10CSR\fR\|(3)," 4 .IX Item "the subject field of any PKCS#10 CSR set in ctx via OSSL_CMP_CTX_set1_p10CSR," .IP "the subject field of any reference certificate given in \fIctx\fR (see \fBOSSL_CMP_CTX_set1_oldCert\fR\|(3)), but only if \fIfor_KUR\fR is nonzero or the \fIctx\fR does not include a Subject Alternative Name." 4 .IX Item "the subject field of any reference certificate given in ctx (see OSSL_CMP_CTX_set1_oldCert), but only if for_KUR is nonzero or the ctx does not include a Subject Alternative Name." .PD .PP The public key included is the first available value of these: .IP "the public key derived from any key set via \fBOSSL_CMP_CTX_set0_newPkey\fR\|(3)," 4 .IX Item "the public key derived from any key set via OSSL_CMP_CTX_set0_newPkey," .PD 0 .IP "the public key of any PKCS#10 CSR given in \fIctx\fR," 4 .IX Item "the public key of any PKCS#10 CSR given in ctx," .IP "the public key of any reference certificate given in \fIctx\fR (see \fBOSSL_CMP_CTX_set1_oldCert\fR\|(3))," 4 .IX Item "the public key of any reference certificate given in ctx (see OSSL_CMP_CTX_set1_oldCert)," .IP "the public key derived from any client's private key set via \fBOSSL_CMP_CTX_set1_pkey\fR\|(3)." 4 .IX Item "the public key derived from any client's private key set via OSSL_CMP_CTX_set1_pkey." .PD .PP The set of X.509 extensions to include is computed as follows. If a PKCS#10 CSR is present in \fIctx\fR, default extensions are taken from there, otherwise the empty set is taken as the initial value. If there is a reference certificate in \fIctx\fR and contains Subject Alternative Names (SANs) and \fBOSSL_CMP_OPT_SUBJECTALTNAME_NODEFAULT\fR is not set, these override any SANs from the PKCS#10 CSR. The extensions are further augmented or overridden by any extensions with the same OIDs included in the \fIctx\fR via \fBOSSL_CMP_CTX_set0_reqExtensions\fR\|(3). The SANs are further overridden by any SANs included in \fIctx\fR via \&\fBOSSL_CMP_CTX_push1_subjectAltName\fR\|(3). Finally, policies are overridden by any policies included in \fIctx\fR via \&\fBOSSL_CMP_CTX_push0_policy\fR\|(3). .PP \&\fBOSSL_CMP_CTX_setup_CRM()\fR also sets the sets the regToken control \fBoldCertID\fR for KUR messages using the issuer name and serial number of the reference certificate, if present. .PP \&\fBOSSL_CMP_MSG_read()\fR loads a DER-encoded OSSL_CMP_MSG from \fIfile\fR. .PP \&\fBOSSL_CMP_MSG_write()\fR stores the given OSSL_CMP_MSG to \fIfile\fR in DER encoding. .PP \&\fBd2i_OSSL_CMP_MSG_bio()\fR parses an ASN.1\-encoded OSSL_CMP_MSG from the BIO \fIbio\fR. It assigns a pointer to the new structure to \fI*msg\fR if \fImsg\fR is not NULL. .PP \&\fBi2d_OSSL_CMP_MSG_bio()\fR writes the OSSL_CMP_MSG \fImsg\fR in ASN.1 encoding to BIO \fIbio\fR. .SH NOTES .IX Header "NOTES" CMP is defined in RFC 4210. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOSSL_CMP_MSG_get0_header()\fR returns the intended pointer value as described above or NULL if the respective entry does not exist and on error. .PP \&\fBOSSL_CMP_MSG_get_bodytype()\fR returns the body type or \-1 on error. .PP \&\fBOSSL_CMP_MSG_get0_certreq_publickey()\fR returns a public key or NULL on error. .PP \&\fBOSSL_CMP_CTX_setup_CRM()\fR returns a pointer to a \fBOSSL_CRMF_MSG\fR on success, NULL on error. .PP \&\fBd2i_OSSL_CMP_MSG_bio()\fR returns the parsed message or NULL on error. .PP \&\fBOSSL_CMP_MSG_read()\fR and \fBd2i_OSSL_CMP_MSG_bio()\fR return the parsed CMP message or NULL on error. .PP \&\fBOSSL_CMP_MSG_write()\fR returns the number of bytes successfully encoded or a negative value if an error occurs. .PP \&\fBi2d_OSSL_CMP_MSG_bio()\fR, \fBOSSL_CMP_MSG_update_transactionID()\fR, and \fBOSSL_CMP_MSG_update_recipNonce()\fR return 1 on success, 0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBOSSL_CMP_CTX_set1_subjectName\fR\|(3), \fBOSSL_CMP_CTX_set1_p10CSR\fR\|(3), \&\fBOSSL_CMP_CTX_set1_oldCert\fR\|(3), \fBOSSL_CMP_CTX_set0_newPkey\fR\|(3), \&\fBOSSL_CMP_CTX_set1_pkey\fR\|(3), \fBOSSL_CMP_CTX_set0_reqExtensions\fR\|(3), \&\fBOSSL_CMP_CTX_push1_subjectAltName\fR\|(3), \fBOSSL_CMP_CTX_push0_policy\fR\|(3) .SH HISTORY .IX Header "HISTORY" The OpenSSL CMP support was added in OpenSSL 3.0. .PP \&\fBOSSL_CMP_MSG_update_recipNonce()\fR was added in OpenSSL 3.0.9. .PP \&\fBOSSL_CMP_MSG_get0_certreq_publickey()\fR was added in OpenSSL 3.3. .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2007\-2024 The OpenSSL Project Authors.
