Set ssl behavior options
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_OPTIONS, long bitmask);
Pass a long with a bitmask to tell libcurl about specific SSL behaviors.
CURLSSLOPT_ALLOW_BEAST 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.
All TLS-based protocols
Added in 7.25.0
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
