NAME

6       CURLOPT_PROXY_SSLKEY_BLOB - private key for proxy cert from memory blob
7

SYNOPSIS

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

DESCRIPTION

15       Pass  a  pointer  to  a  curl_blob  structure that contains information
16       (pointer and size) about the private key for connecting  to  the  HTTPS
17       proxy.  Compatible with OpenSSL. The format (like "PEM") must be speci‐
18       fied with CURLOPT_PROXY_SSLKEYTYPE(3).
19
20       If the blob is initialized with the flags member  of  struct  curl_blob
21       set to CURL_BLOB_COPY, the application does not have to keep the buffer
22       around after setting this.
23

DEFAULT

25       NULL
26

PROTOCOLS

28       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
29

EXAMPLE

31       CURL *curl = curl_easy_init();
32       if(curl) {
33         struct curl_blob blob;
34         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
35         curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
36         blob.data = certificateData;
37         blob.len = filesize;
38         blob.flags = CURL_BLOB_COPY;
39         curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT_BLOB, &blob);
40         curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERTTYPE, "PEM");
41
42         blob.data = privateKeyData;
43         blob.len = privateKeySize;
44         curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY_BLOB, &blob);
45         curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
46         ret = curl_easy_perform(curl);
47         curl_easy_cleanup(curl);
48       }

AVAILABILITY

51       Added in 7.71.0. This option is supported by the OpenSSL backends.
52

RETURN VALUE

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