.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.

\fICURLSSLOPT_ALLOW_BEAST\fP is the only supported bit and by setting this the
user will tell 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.
.SH DEFAULT
0
.SH PROTOCOLS
All TLS-based protocols
.SH EXAMPLE
TODO
.SH AVAILABILITY
Added in 7.25.0
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
