The string should be 39 the filename of your client certificate used to connect to the HTTPS proxy. 40 The default format "PEM", and can be changed with 41 CURLOPT_PROXY_SSLCERTTYPE(3). 42 43 When using a client certificate, you most likely also need to provide a 44 private key with CURLOPT_PROXY_SSLKEY(3). 45 46 The application does not have to keep the string around after setting this 47 option. 48 49 Using this option multiple times makes the last set string override the 50 previous ones. Set it to NULL to disable its use again. 51 52 # DEFAULT 53 54 NULL 55 56 # %PROTOCOLS% 57 58 # EXAMPLE 59 60 ~~~c 61 int main(void) 62 { 63 CURL *curl = curl_easy_init(); 64 if(curl) { 65 CURLcode res; 66 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); 67 curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy"); 68 curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT, "client.pem"); 69 curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY, "key.pem"); 70 curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret"); 71 res = curl_easy_perform(curl); 72 curl_easy_cleanup(curl); 73 } 74 } 75 ~~~ 76 77 # %AVAILABILITY% 78 79 # RETURN VALUE 80 81 curl_easy_setopt(3) returns a CURLcode indicating success or error. 82 83 CURLE_OK (0) means everything was OK, non-zero means an error occurred, see 84 libcurl-errors(3).
