.TH CURLOPT_PROXY_SSL_OPTIONS 3 "16 Nov 2016" "libcurl 7.52.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_PROXY_SSL_OPTIONS \- set proxy SSL behavior options
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_OPTIONS, long bitmask);
|
|
.SH DESCRIPTION
|
|
Pass a long with a bitmask to tell libcurl about specific SSL
|
|
behaviors. Available bits:
|
|
.IP CURLSSLOPT_ALLOW_BEAST
|
|
Tells libcurl to not attempt to use any workarounds for a security flaw in the
|
|
SSL3 and TLS1.0 protocols. If this option isn't used or this bit is set to 0,
|
|
the SSL layer libcurl uses may use a work-around for this flaw although it
|
|
might cause interoperability problems with some (older) SSL
|
|
implementations. WARNING: avoiding this work-around lessens the security, and
|
|
by setting this option to 1 you ask for exactly that. This option is only
|
|
supported for DarwinSSL, NSS and OpenSSL.
|
|
.IP CURLSSLOPT_NO_REVOKE
|
|
Tells libcurl to disable certificate revocation checks for those SSL backends
|
|
where such behavior is present. This option is only supported for Schannel
|
|
(the native Windows SSL library), with an exception in the case of Windows'
|
|
Untrusted Publishers blacklist which it seems can't be bypassed. (Added in
|
|
7.44.0)
|
|
.IP CURLSSLOPT_NO_PARTIALCHAIN
|
|
Tells libcurl to not accept "partial" certificate chains, which it otherwise
|
|
does by default. This option is only supported for OpenSSL and will fail the
|
|
certificate verification if the chain ends with an intermediate certificate
|
|
and not with a root cert. (Added in 7.68.0)
|
|
|
|
.IP CURLSSLOPT_REVOKE_BEST_EFFORT
|
|
Tells libcurl to ignore certificate revocation checks in case of missing or
|
|
offline distribution points for those SSL backends where such behavior is
|
|
present. This option is only supported for Schannel (the native Windows SSL
|
|
library). If combined with \fICURLSSLOPT_NO_REVOKE\fP, the latter takes
|
|
precedence. (Added in 7.70.0)
|
|
.SH DEFAULT
|
|
0
|
|
.SH PROTOCOLS
|
|
All TLS-based protocols
|
|
.SH AVAILABLE
|
|
Added in 7.52.0
|
|
.SH EXAMPLE
|
|
.nf
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
|
|
/* weaken TLS only for use with silly proxies */
|
|
curl_easy_setopt(curl, CURLOPT_PROXY_SSL_OPTIONS, CURLSSLOPT_ALLOW_BEAST |
|
|
CURLSSLOPT_NO_REVOKE);
|
|
ret = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
.fi
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
