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

       This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

       This option works only with the following TLS backends: OpenSSL

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 curl 7.71.0

RETURN VALUE

       Returns  CURLE_OK  if  TLS enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if
       there was insufficient heap space.
