34 OSSL_CMP_MSG_get0_header() returns the header of the given CMP message.
36 OSSL_CMP_MSG_get_bodytype() returns the body type of the given CMP message.
38 OSSL_CMP_MSG_get0_certreq_publickey() expects that I<msg> is a certificate request
39 messsage and returns the public key in its certificate template if present.
41 OSSL_CMP_MSG_update_transactionID() updates the transactionID field
42 in the header of the given message according to the CMP_CTX.
43 If I<ctx> does not contain a transaction ID, a fresh one is created before.
44 The message gets re-protected (if protecting requests is required).
46 OSSL_CMP_MSG_update_recipNonce() updates the recipNonce field
47 in the header of the given message according to the CMP_CTX.
48 The message gets re-protected (if protecting requests is required).
50 OSSL_CMP_CTX_setup_CRM() creates a CRMF certificate request message
51 from various information provided in the CMP context argument I<ctx>
52 for inclusion in a CMP request message based on details contained in I<ctx>.
53 The I<rid> argument defines the request identifier to use, which typically is 0.
55 The subject DN included in the certificate template is
56 the first available value of these:
60 =item any subject name in I<ctx> set via L<OSSL_CMP_CTX_set1_subjectName(3)> -
61 if it is the NULL-DN (i.e., any empty sequence of RDNs), no subject is included,
63 =item the subject field of any PKCS#10 CSR set in I<ctx>
64 via L<OSSL_CMP_CTX_set1_p10CSR(3)>,
66 =item the subject field of any reference certificate given in I<ctx>
67 (see L<OSSL_CMP_CTX_set1_oldCert(3)>), but only if I<for_KUR> is nonzero
68 or the I<ctx> does not include a Subject Alternative Name.
72 The public key included is the first available value of these:
76 =item the public key derived from any key set via L<OSSL_CMP_CTX_set0_newPkey(3)>,
78 =item the public key of any PKCS#10 CSR given in I<ctx>,
80 =item the public key of any reference certificate given in I<ctx>
81 (see L<OSSL_CMP_CTX_set1_oldCert(3)>),
83 =item the public key derived from any client's private key
84 set via L<OSSL_CMP_CTX_set1_pkey(3)>.
88 The set of X.509 extensions to include is computed as follows.
89 If a PKCS#10 CSR is present in I<ctx>, default extensions are taken from there,
90 otherwise the empty set is taken as the initial value.
91 If there is a reference certificate in I<ctx> and contains Subject Alternative
92 Names (SANs) and B<OSSL_CMP_OPT_SUBJECTALTNAME_NODEFAULT> is not set,
93 these override any SANs from the PKCS#10 CSR.
94 The extensions are further augmented or overridden by any extensions with the
95 same OIDs included in the I<ctx> via L<OSSL_CMP_CTX_set0_reqExtensions(3)>.
96 The SANs are further overridden by any SANs included in I<ctx> via
97 L<OSSL_CMP_CTX_push1_subjectAltName(3)>.
98 Finally, policies are overridden by any policies included in I<ctx> via
99 L<OSSL_CMP_CTX_push0_policy(3)>.
101 OSSL_CMP_CTX_setup_CRM() also sets the sets the regToken control B<oldCertID>
102 for KUR messages using the issuer name and serial number of the reference
103 certificate, if present.
105 OSSL_CMP_MSG_read() loads a DER-encoded OSSL_CMP_MSG from I<file>.
107 OSSL_CMP_MSG_write() stores the given OSSL_CMP_MSG to I<file> in DER encoding.
109 d2i_OSSL_CMP_MSG_bio() parses an ASN.1-encoded OSSL_CMP_MSG from the BIO I<bio>.
110 It assigns a pointer to the new structure to I<*msg> if I<msg> is not NULL.
112 i2d_OSSL_CMP_MSG_bio() writes the OSSL_CMP_MSG I<msg> in ASN.1 encoding
117 CMP is defined in RFC 4210.
121 OSSL_CMP_MSG_get0_header() returns the intended pointer value as described above
122 or NULL if the respective entry does not exist and on error.
124 OSSL_CMP_MSG_get_bodytype() returns the body type or -1 on error.
126 OSSL_CMP_MSG_get0_certreq_publickey() returns a public key or NULL on error.
128 OSSL_CMP_CTX_setup_CRM() returns a pointer to a B<OSSL_CRMF_MSG> on success,
131 d2i_OSSL_CMP_MSG_bio() returns the parsed message or NULL on error.
133 OSSL_CMP_MSG_read() and d2i_OSSL_CMP_MSG_bio()
134 return the parsed CMP message or NULL on error.
136 OSSL_CMP_MSG_write() returns the number of bytes successfully encoded or a
137 negative value if an error occurs.
139 i2d_OSSL_CMP_MSG_bio(), OSSL_CMP_MSG_update_transactionID(),
140 and OSSL_CMP_MSG_update_recipNonce()
141 return 1 on success, 0 on error.
