=head1 NAME
|
|
|
|
OSSL_CMP_MSG_http_perform
|
|
- client-side HTTP(S) transfer of a CMP request-response pair
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/cmp.h>
|
|
|
|
OSSL_CMP_MSG *OSSL_CMP_MSG_http_perform(OSSL_CMP_CTX *ctx,
|
|
const OSSL_CMP_MSG *req);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
OSSL_CMP_MSG_http_perform() sends the given PKIMessage I<req>
|
|
to the CMP server specified in I<ctx> via L<OSSL_CMP_CTX_set1_server(3)>
|
|
and optionally L<OSSL_CMP_CTX_set_serverPort(3)>, using
|
|
any "CMP alias" optionally specified via L<OSSL_CMP_CTX_set1_serverPath(3)>.
|
|
The default port is 80 for HTTP and 443 for HTTPS; the default path is "/".
|
|
On success the function returns the server's response PKIMessage.
|
|
|
|
The function makes use of any HTTP callback function
|
|
set via L<OSSL_CMP_CTX_set_http_cb(3)>.
|
|
It respects any timeout value set via L<OSSL_CMP_CTX_set_option(3)>
|
|
with an B<OSSL_CMP_OPT_MSG_TIMEOUT> argument.
|
|
It also respects any HTTP(S) proxy options set via L<OSSL_CMP_CTX_set1_proxy(3)>
|
|
and L<OSSL_CMP_CTX_set1_no_proxy(3)> and the respective environment variables.
|
|
Proxying plain HTTP is supported directly,
|
|
while using a proxy for HTTPS connections requires a suitable callback function
|
|
such as L<OSSL_HTTP_proxy_connect(3)>.
|
|
|
|
=head1 NOTES
|
|
|
|
CMP is defined in RFC 4210.
|
|
HTTP transfer for CMP is defined in RFC 6712.
