NAME

       CURLOPT_PROXY_SSLCERT_BLOB - SSL proxy client certificate from memory blob

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERT_BLOB,
                                 struct curl_blob *blob);

DESCRIPTION

       Pass  a  pointer  to  a curl_blob structure, which contains information (pointer and size) about a memory
       block with binary data of the certificate used to connect to the HTTPS proxy. The format must be "P12" on
       Secure  Transport  or  Schannel.  The format must be "P12" or "PEM" on OpenSSL. The string "P12" or "PEM"
       must be specified with CURLOPT_PROXY_SSLCERTTYPE(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.

       This option is an alternative to CURLOPT_PROXY_SSLCERT(3) which instead expects a filename as input.

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, Schannel and Secure Transport

EXAMPLE

       extern char *certificateData; /* point to data */
       extern size_t filesize; /* size of the data */

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           struct curl_blob blob;
           blob.data = certificateData;
           blob.len = filesize;
           blob.flags = CURL_BLOB_COPY;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
           curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY, "key.pem");
           curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
           curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT_BLOB, &blob);
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

       Added in curl 7.71.0

RETURN VALUE

       curl_easy_setopt(3) returns a CURLcode indicating success or error.

       CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
