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_BLOB - proxy Certificate Authority (CA) bundle in PEM format
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAINFO_BLOB,
|
|
struct curl_blob *stblob);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
This option is for connecting to an HTTPS proxy, not an HTTPS server.
|
|
|
|
Pass a pointer to a curl_blob structure, which contains information (pointer
|
|
and size) about a memory block with binary data of PEM encoded content holding
|
|
one or more certificates to verify the HTTPS proxy with.
|
|
|
|
If the blob is initialized with the flags member of struct curl_blob set to
|
|
CURL_BLOB_COPY, the application does not have to keep the buffer around after
|
|
setting this.
|
|
|
|
If CURLOPT_PROXY_SSL_VERIFYPEER(3) is zero and you avoid verifying the
|
|
server's certificate, CURLOPT_PROXY_CAINFO_BLOB(3) is not needed.
|
|
|
|
This option overrides CURLOPT_PROXY_CAINFO(3).
|
|
|
|
# DEFAULT
|
|
|
|
NULL
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
#include <string.h> /* for strlen */
|
|
|
|
extern char *strpem; /* strpem must point to a PEM string */
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
struct curl_blob blob;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
/* using an HTTPS proxy */
|
|
curl_easy_setopt(curl, CURLOPT_PROXY, "https://localhost:443");
|
|
blob.data = strpem;
|
|
blob.len = strlen(strpem);
|
|
blob.flags = CURL_BLOB_COPY;
|
|
curl_easy_setopt(curl, CURLOPT_PROXY_CAINFO_BLOB, &blob);
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
