.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.
|
|
|
|
\fICURLSSLOPT_ALLOW_BEAST\fP 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.
|
|
|
|
\fICURLSSLOPT_NO_REVOKE\fP tells libcurl to disable certificate revocation
|
|
checks for those SSL backends where such behavior is present. \fBCurrently
|
|
this option is only supported for WinSSL (the native Windows SSL library),
|
|
with an exception in the case of Windows' Untrusted Publishers blacklist which
|
|
it seems can't be bypassed.\fP This option may have broader support to
|
|
accommodate other SSL backends in the future.
