29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_OPTIONS, long bitmask);
31 Pass a long with a bitmask to tell libcurl about specific SSL behaviors.
33 \fICURLSSLOPT_ALLOW_BEAST\fP is the only supported bit and by setting this the
34 user will tell libcurl to not attempt to use any workarounds for a security
35 flaw in the SSL3 and TLS1.0 protocols. If this option isn't used or this bit
36 is set to 0, the SSL layer libcurl uses may use a work-around for this flaw
37 although it might cause interoperability problems with some (older) SSL
38 implementations. WARNING: avoiding this work-around lessens the security, and
39 by setting this option to 1 you ask for exactly that.
43 All TLS-based protocols
49 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
