CURLOPT_PROXY_SSLKEY_BLOB(3)

NAME

CURLOPT_PROXY_SSLKEY_BLOB - private key for proxy cert from memory blob

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLKEY_BLOB,
struct curl_blob *blob);

DESCRIPTION

Pass a pointer to a curl_blob structure that contains information (pointer and size) about the private key for connecting to the HTTPS proxy. Compatible with OpenSSL. The format (like "PEM") must be specified with CURLOPT_PROXY_SSLKEYTYPE(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.

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;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
blob.data = certificateData;
blob.len = filesize;
blob.flags = CURL_BLOB_COPY;
curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT_BLOB, &blob);
curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERTTYPE, "PEM");

blob.data = privateKeyData;
blob.len = privateKeySize;
curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY_BLOB, &blob);
curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}

AVAILABILITY

Added in 7.71.0. This option is supported by the OpenSSL 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.
