NAME
CURLOPT_PROXY_SSLKEY_BLOB - private key for proxy cert from memory blob
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLKEY_BLOB,
struct curl_blob *blob);
DESCRIPTION
Pass a pointer to a curl_blob structure that contains information (pointer and size) about the private
key for connecting to the HTTPS proxy. Compatible with OpenSSL. The format (like "PEM") must be specified
with CURLOPT_PROXY_SSLKEYTYPE(3).
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.
DEFAULT
NULL
PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLE
extern char *certificateData; /* point to data */
extern size_t filesize; /* size of data */
extern char *privateKeyData; /* point to data */
extern size_t privateKeySize; /* size */
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/");
curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
blob.data = certificateData;
blob.len = filesize;
blob.flags = CURL_BLOB_COPY;
curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT_BLOB, &blob);
curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERTTYPE, "PEM");
blob.data = privateKeyData;
blob.len = privateKeySize;
curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY_BLOB, &blob);
curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
AVAILABILITY
Added in 7.71.0. This option is supported by the OpenSSL backends.
RETURN VALUE
Returns CURLE_OK if TLS enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was
insufficient heap space.
