<p class="level0"><span Class="emphasis">CURLSSLOPT_ALLOW_BEAST</span> 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.

<p class="level0"><span Class="emphasis">CURLSSLOPT_NO_REVOKE</span> tells libcurl to disable certificate revocation checks for those SSL backends where such behavior is present. <span class="bold">Currently 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.</span> This option may have broader support to accommodate other SSL backends in the future. <a href="https://curl.haxx.se/docs/ssl-compared.html">https://curl.haxx.se/docs/ssl-compared.html</a>
