Its arguments are the \fB\s-1OSSL_CMP_SRV_CTX\s0\fR \fIsrv_ctx\fR and the \s-1CMP\s0 request message \&\fIreq\fR. It does the typical generic checks on \fIreq\fR, calls the respective callback function (if present) for more specific processing, and then assembles a result message, which may be a \s-1CMP\s0 error message. If after return of the function the expression \&\fIOSSL_CMP_CTX_get_status(OSSL_CMP_SRV_CTX_get0_cmp_ctx(srv_ctx))\fR yields \-1 then the function has closed the current transaction, which may be due to normal successful end of the transaction or due to an error. .PP \&\fBOSSL_CMP_CTX_server_perform()\fR is an interface to \&\fBOSSL_CMP_SRV_process_request()\fR that can be used by a \s-1CMP\s0 client in the same way as \fBOSSL_CMP_MSG_http_perform\fR\|(3). The \fB\s-1OSSL_CMP_SRV_CTX\s0\fR must be set as \fItransfer_cb_arg\fR of \fIclient_ctx\fR. .PP \&\fBOSSL_CMP_SRV_CTX_new()\fR creates and initializes an \fB\s-1OSSL_CMP_SRV_CTX\s0\fR structure associated with the library context \fIlibctx\fR and property query string \&\fIpropq\fR, both of which may be \s-1NULL\s0 to select the defaults. .PP \&\fBOSSL_CMP_SRV_CTX_free()\fR deletes the given \fIsrv_ctx\fR. .PP \&\fBOSSL_CMP_SRV_CTX_init()\fR sets in the given \fIsrv_ctx\fR a custom server context pointer as well as callback functions performing the specific processing of \s-1CMP\s0 certificate requests, revocation requests, certificate confirmation requests, general messages, error messages, and poll requests. All arguments except \fIsrv_ctx\fR may be \s-1NULL.\s0 If a callback for some message type is not given this means that the respective type of \s-1CMP\s0 message is not supported by the server. .PP \&\fBOSSL_CMP_SRV_CTX_get0_cmp_ctx()\fR returns the \fB\s-1OSSL_CMP_CTX\s0\fR from the \fIsrv_ctx\fR. .PP \&\fBOSSL_CMP_SRV_CTX_get0_custom_ctx()\fR returns the custom server context from \&\fIsrv_ctx\fR that has been set using \fBOSSL_CMP_SRV_CTX_init()\fR. .PP \&\fBOSSL_CMP_SRV_CTX_set_send_unprotected_errors()\fR enables sending error messages and other forms of negative responses unprotected. .PP \&\fBOSSL_CMP_SRV_CTX_set_accept_unprotected()\fR enables acceptance of requests without protection of with invalid protection. .PP \&\fBOSSL_CMP_SRV_CTX_set_accept_raverified()\fR enables acceptance of ir/cr/kur messages with \s-1POPO\s0 'RAVerified'. .PP \&\fBOSSL_CMP_SRV_CTX_set_grant_implicit_confirm()\fR enables granting implicit confirmation of newly enrolled certificates if requested. .SH "NOTES" .IX Header "NOTES" \&\s-1CMP\s0 is defined in \s-1RFC 4210\s0 (and \s-1CRMF\s0 in \s-1RFC 4211\s0). .PP So far the \s-1CMP\s0 server implementation is limited to one request per \s-1CMP\s0 message (and consequently to at most one response component per \s-1CMP\s0 message). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOSSL_CMP_SRV_CTX_new()\fR returns a \fB\s-1OSSL_CMP_SRV_CTX\s0\fR structure on success, \&\s-1NULL\s0 on error. .PP \&\fBOSSL_CMP_SRV_CTX_free()\fR does not return a value. .PP \&\fBOSSL_CMP_SRV_CTX_get0_cmp_ctx()\fR returns a \fB\s-1OSSL_CMP_CTX\s0\fR structure on success, \&\s-1NULL\s0 on error. .PP \&\fBOSSL_CMP_SRV_CTX_get0_custom_ctx()\fR returns the custom server context that has been set using \fBOSSL_CMP_SRV_CTX_init()\fR. .PP All other functions return 1 on success, 0 on error. .SH "HISTORY" .IX Header "HISTORY" The OpenSSL \s-1CMP\s0 support was added in OpenSSL 3.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2007\-2021 The OpenSSL Project Authors.
