This commit changes the behavior of CURLSSLOPT_NATIVE_CA so that it does
not override CURLOPT_CAINFO / CURLOPT_CAPATH, or the hardcoded default
locations. Instead the CA store can now be used at the same time.
The change is due to the impending release. The issue is still being
discussed. The behavior of CURLSSLOPT_NATIVE_CA is subject to change and
is now documented as experimental.

.TH CURLOPT_SSL_OPTIONS 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_SSL_OPTIONS \- set SSL behavior options
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_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 block list 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)
|
|
.IP CURLSSLOPT_NATIVE_CA
|
|
Tell libcurl to use the operating system's native CA store for certificate
|
|
verification. Works only on Windows when built to use OpenSSL. This option is
|
|
experimental and behavior is subject to change.
|
|
(Added in 7.71.0)
|
|
.SH DEFAULT
|
|
0
|
|
.SH PROTOCOLS
|
|
All TLS-based protocols
|

.SH EXAMPLE
|

|
CURL *curl = curl_easy_init();

curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
/* weaken TLS only for use with silly servers */
|
|
curl_easy_setopt(curl, CURLOPT_SSL_OPTIONS, CURLSSLOPT_ALLOW_BEAST |
|
|
CURLSSLOPT_NO_REVOKE);

.SH RETURN VALUE
|
|
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
