Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
CURLOPT_PROXY_CAINFO - path to proxy Certificate Authority (CA) bundle
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAINFO, char *path);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
This option is for connecting to an HTTPS proxy, not an HTTPS server.
|
|
|
|
Pass a char pointer to a null-terminated string naming a file holding one or
|
|
more certificates to verify the HTTPS proxy with.
|
|
|
|
If CURLOPT_PROXY_SSL_VERIFYPEER(3) is zero and you avoid verifying the
|
|
server's certificate, CURLOPT_PROXY_CAINFO(3) need not even indicate an
|
|
accessible file.
|
|
|
|
This option is by default set to the system path where libcurl's CA
|
|
certificate bundle is assumed to be stored, as established at build time.
|
|
|
|
(iOS and macOS only) If curl is built against Secure Transport, then this
|
|
option is supported for backward compatibility with other SSL engines, but it
|
|
should not be set. If the option is not set, then curl uses the certificates
|
|
in the system and user Keychain to verify the peer, which is the preferred
|
|
method of verifying the peer's certificate chain.
|
|
|
|
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_CAINFO(3).
|
|
|
|
# DEFAULT
|
|
|
|
Built-in system specific
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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_CAINFO, "/etc/certs/cabundle.pem");
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}

# AVAILABILITY
|
|
|
|
Added in 7.52.0
|

For TLS backends that do not support certificate files, the
|
|

|
|
https://curl.se/docs/ssl-compared.html
|
|
|
|
# RETURN VALUE
|
|
|
|
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or
|
|
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
