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 speciā€
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       }
49

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.
