NAME

6       CURLOPT_PROXY_SSLCERT_BLOB  -  SSL proxy client certificate from memory
7       blob
8

SYNOPSIS

10       #include <curl/curl.h>
11
12       CURLcode  curl_easy_setopt(CURL  *handle,   CURLOPT_PROXY_SSLCERT_BLOB,
13       struct curl_blob *blob);
14

DESCRIPTION

16       Pass  a  pointer  to  a curl_blob structure, which contains information
17       (pointer and size) about a memory block with binary data  of  the  cer‐
18       tificate  used  to connect to the HTTPS proxy. The format must be "P12"
19       on Secure Transport or Schannel. The format must be "P12" or  "PEM"  on
20       OpenSSL.   The  string  "P12"  or  "PEM"  must  be  specified with CUR‐
21       LOPT_PROXY_SSLCERTTYPE(3).
22
23       If the blob is initialized with the flags member  of  struct  curl_blob
24       set to CURL_BLOB_COPY, the application does not have to keep the buffer
25       around after setting this.
26
27       This option is an alternative to CURLOPT_PROXY_SSLCERT(3) which instead
28       expects a file name as input.
29

DEFAULT

31       NULL
32

PROTOCOLS

34       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
35

EXAMPLE

37       CURL *curl = curl_easy_init();
38       if(curl) {
39         struct curl_blob blob;
40         blob.data = certificateData;
41         blob.len = filesize;
42         blob.flags = CURL_BLOB_COPY;
43         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
44         curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
45         curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY, "key.pem");
46         curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
47         curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT_BLOB, &blob);
48         ret = curl_easy_perform(curl);
49         curl_easy_cleanup(curl);
50       }
51

AVAILABILITY

53       Added  in  libcurl 7.71.0. This option is supported by the OpenSSL, Se‐
54       cure Transport and Schannel backends.
55

RETURN VALUE

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