CURLOPT_PROXY_SSLKEY_BLOB − private key for proxy cert from memory blob
#include <curl/curl.h>
CURLcode
curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLKEY_BLOB,
struct curl_blob *blob);
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.
NULL
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

Added in 7.71.0. This option is supported by the OpenSSL backends.
Returns CURLE_OK if TLS enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
