NAME

       CURLOPT_SSLCERT_BLOB - SSL client certificate from memory blob

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT_BLOB,
                                 struct curl_blob *stblob);

DESCRIPTION

       Pass  a  pointer  to  a  curl_blob structure, which contains (pointer and size) a client certificate. The
       format must be "P12" on Secure Transport or Schannel. The format must be "P12" or "PEM" on  OpenSSL.  The
       format must be "DER" or "PEM" on mbedTLS. The format must be specified with CURLOPT_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_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, Secure Transport, mbedTLS  and
       wolfSSL

EXAMPLE

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

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           struct curl_blob stblob;
           stblob.data = certificateData;
           stblob.len = filesize;
           stblob.flags = CURL_BLOB_COPY;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           curl_easy_setopt(curl, CURLOPT_SSLCERT_BLOB, &stblob);
           curl_easy_setopt(curl, CURLOPT_SSLCERTTYPE, "P12");
           curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
           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).
