30 OSSL_CMP_MSG_get0_header() returns the header of the given CMP message.
32 OSSL_CMP_MSG_get_bodytype() returns the body type of the given CMP message.
34 OSSL_CMP_MSG_update_transactionID() updates the transactionID field
35 in the header of the given message according to the CMP_CTX.
36 This requires re-protecting the message (if it was protected).
38 OSSL_CMP_CTX_setup_CRM() creates a CRMF certificate request message
39 from various information provided in the CMP context argument I<ctx>
40 for inclusion in a CMP request message based on details contained in I<ctx>.
41 The I<rid> argument defines the request identifier to use, which typically is 0.
43 The subject DN included in the certificate template is
44 the first available value of these:
48 =item any subject name in I<ctx> set via L<OSSL_CMP_CTX_set1_subjectName(3)>,
50 =item the subject field of any PKCS#10 CSR is given in I<ctx>, or
52 =item the subject field of any reference certificate given in I<ctx>
53 (see L<OSSL_CMP_CTX_set1_oldCert(3)>), if I<for_KUR> is nonzero
54 or the I<ctx> does not include a Subject Alternative Name.
58 The public key included is the first available value of these:
62 =item the public key derived from any key set via L<OSSL_CMP_CTX_set0_newPkey(3)>,
64 =item the public key of any PKCS#10 CSR is given in I<ctx>,
66 =item the public key of any reference certificate given in I<ctx>, or
68 =item the public key derived from any client's private key
69 set via L<OSSL_CMP_CTX_set1_pkey(3)>.
73 The set of X.509 extensions to include is computed as follows.
74 If a PKCS#10 CSR is present in I<ctx>, default extensions are taken from there,
75 otherwise the empty set is taken as the initial value.
76 If there is a reference certificate in I<ctx> and contains Subject Alternative
77 Names (SANs) and B<OSSL_CMP_OPT_SUBJECTALTNAME_NODEFAULT> is not set,
78 these override any SANs from the PKCS#10 CSR.
79 The extensions are further augmented or overridden by any extensions with the
80 same OIDs included in the I<ctx> via L<OSSL_CMP_CTX_set0_reqExtensions(3)>.
81 The SANs are further overridden by any SANs included in I<ctx> via
82 L<OSSL_CMP_CTX_push1_subjectAltName(3)>.
83 Finally, policies are overridden by any policies included in I<ctx> via
84 L<OSSL_CMP_CTX_push0_policy(3)>.
86 OSSL_CMP_CTX_setup_CRM() also sets the sets the regToken control B<oldCertID>
87 for KUR messages using the issuer name and serial number of the reference
88 certificate, if present.
90 OSSL_CMP_MSG_read() loads a DER-encoded OSSL_CMP_MSG from I<file>.
92 OSSL_CMP_MSG_write() stores the given OSSL_CMP_MSG to I<file> in DER encoding.
94 d2i_OSSL_CMP_MSG_bio() parses an ASN.1-encoded OSSL_CMP_MSG from the BIO I<bio>.
95 It assigns a pointer to the new structure to I<*msg> if I<msg> is not NULL.
97 i2d_OSSL_CMP_MSG_bio() writes the OSSL_CMP_MSG I<msg> in ASN.1 encoding
102 CMP is defined in RFC 4210.
106 OSSL_CMP_MSG_get0_header() returns the intended pointer value as described above
107 or NULL if the respective entry does not exist and on error.
109 OSSL_CMP_MSG_get_bodytype() returns the body type or -1 on error.
111 OSSL_CMP_CTX_setup_CRM() returns a pointer to a OSSL_CRMF_MSG on success,
114 d2i_OSSL_CMP_MSG_bio() returns the parsed message or NULL on error.
116 OSSL_CMP_MSG_read() and d2i_OSSL_CMP_MSG_bio()
117 return the parsed CMP message or NULL on error.
119 OSSL_CMP_MSG_write() and i2d_OSSL_CMP_MSG_bio() return
120 the number of bytes successfully encoded or a negative value if an error occurs.
122 OSSL_CMP_MSG_update_transactionID() returns 1 on success, 0 on error.
