| .TH CURLOPT_PROXY_SSL_OPTIONS 3 "May 31, 2017" "libcurl 7.58.0" "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. |
