     19 # NAME
     20 
     21 CURLOPT_PROXY_SSL_VERIFYHOST - verify the proxy certificate's name against host
     22 
     23 # SYNOPSIS
     24 
     25 ~~~c
     26 #include <curl/curl.h>
     27 
     28 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_VERIFYHOST,
     29                           long verify);
     30 ~~~

     32 # DESCRIPTION
     33 
     34 Pass a long set to 2L as asking curl to *verify* in the HTTPS proxy's
     35 certificate name fields against the proxy name.
     36 
     37 This option determines whether libcurl verifies that the proxy cert contains
     38 the correct name for the name it is known as.
     39 
     40 When CURLOPT_PROXY_SSL_VERIFYHOST(3) is 2, the proxy certificate must
     41 indicate that the server is the proxy to which you meant to connect to, or the
     42 connection fails.
     43 
     44 curl considers the proxy the intended one when the Common Name field or a
     45 Subject Alternate Name field in the certificate matches the hostname in the
     46 proxy string which you told curl to use.
     47 
     48 If *verify* value is set to 1:
     49 
     50 In 7.28.0 and earlier: treated as a debug option of some sorts, not supported
     51 anymore due to frequently leading to programmer mistakes.
     52 
     53 From 7.28.1 to 7.65.3: setting it to 1 made curl_easy_setopt(3) return
     54 an error and leaving the flag untouched.
     55 
     56 From 7.66.0: treats 1 and 2 the same.
     57 
     58 When the *verify* value is 0L, the connection succeeds regardless of the
     59 names used in the certificate. Use that ability with caution.
     60 
     61 See also CURLOPT_PROXY_SSL_VERIFYPEER(3) to verify the digital signature
     62 of the proxy certificate.

     90 
     91 curl_easy_setopt(3) returns a CURLcode indicating success or error.
     92 
     93 CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
     94 libcurl-errors(3).
