NAME

6       OSSL_CMP_MSG_http_perform - client-side HTTP(S) transfer of a CMP
7       request-response pair
8

SYNOPSIS

10        #include <openssl/cmp.h>
11
12        OSSL_CMP_MSG *OSSL_CMP_MSG_http_perform(OSSL_CMP_CTX *ctx,
13                                                const OSSL_CMP_MSG *req);
14

DESCRIPTION

16       OSSL_CMP_MSG_http_perform() sends the given PKIMessage req to the CMP
17       server specified in ctx via OSSL_CMP_CTX_set1_server(3) and optionally
18       OSSL_CMP_CTX_set_serverPort(3), using any "CMP alias" optionally
19       specified via OSSL_CMP_CTX_set1_serverPath(3).  The default port is 80
20       for HTTP and 443 for HTTPS; the default path is "/".  On success the
21       function returns the server's response PKIMessage.
22
23       The function makes use of any HTTP callback function set via
24       OSSL_CMP_CTX_set_http_cb(3).  It respects any timeout value set via
25       OSSL_CMP_CTX_set_option(3) with an OSSL_CMP_OPT_MSG_TIMEOUT argument.
26       It also respects any HTTP(S) proxy options set via
27       OSSL_CMP_CTX_set1_proxy(3) and OSSL_CMP_CTX_set1_no_proxy(3) and the
28       respective environment variables.  Proxying plain HTTP is supported
29       directly, while using a proxy for HTTPS connections requires a suitable
30       callback function such as OSSL_HTTP_proxy_connect(3).
31

NOTES

33       CMP is defined in RFC 4210.  HTTP transfer for CMP is defined in RFC
34       6712.
35

RETURN VALUES

37       OSSL_CMP_MSG_http_perform() returns a CMP message on success, else
38       NULL.
