CURLOPT_PROXY_SSLKEY_BLOB(3)                          curl_easy_setopt options

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.
