CURLOPT_PROXY_CAPATH(3) | Library Functions Manual | CURLOPT_PROXY_CAPATH(3) |
NAME¶
CURLOPT_PROXY_CAPATH - directory holding HTTPS proxy CA certificates
SYNOPSIS¶
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAPATH, char *capath);
DESCRIPTION¶
Pass a char pointer to a null-terminated string naming a directory holding multiple CA certificates to verify the HTTPS proxy with. If libcurl is built against OpenSSL, the certificate directory must be prepared using the OpenSSL c_rehash utility. This makes sense only when CURLOPT_PROXY_SSL_VERIFYPEER(3) is enabled (which it is by default).
The application does not have to keep the string around after setting this option.
The default value for this can be figured out with CURLINFO_CAPATH(3).
DEFAULT¶
NULL
PROTOCOLS¶
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
This option works only with the following TLS backends: GnuTLS, OpenSSL and mbedTLS
EXAMPLE¶
int main(void) {
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
/* using an HTTPS proxy */
curl_easy_setopt(curl, CURLOPT_PROXY, "https://localhost:443");
curl_easy_setopt(curl, CURLOPT_PROXY_CAPATH, "/etc/cert-dir");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
} }
AVAILABILITY¶
Added in 7.52.0
mbedTLS support added in 7.56.0.
RETURN VALUE¶
CURLE_OK if supported; or an error such as:
CURLE_NOT_BUILT_IN - Not supported by the SSL backend
CURLE_UNKNOWN_OPTION
CURLE_OUT_OF_MEMORY
