CURLOPT_PROXY_SSLCERT_BLOB(3)                         curl_easy_setopt options

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
       _PROXY_SSLCERTTYPE&section=3">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 _PROXY_SSLCERT&section=3">CURLOPT_PROXY_SSLCERT(3) which instead
       expects a file name as input.

DEFAULT
       NULL

PROTOCOLS
       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         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);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Added in libcurl 7.71.0. This option is supported by the OpenSSL,
       Secure Transport and Schannel 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.
