21# NAME
22
23CURLOPT_PROXY_SSLCERT_BLOB - SSL proxy client certificate from memory blob
24
25# SYNOPSIS
26
27~~~c
28#include <curl/curl.h>
29
30CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERT_BLOB,
31                          struct curl_blob *blob);
32~~~
33
34# DESCRIPTION
35
36Pass a pointer to a curl_blob structure, which contains information (pointer
37and size) about a memory block with binary data of the certificate used to
38connect to the HTTPS proxy. The format must be "P12" on Secure Transport or
39Schannel. The format must be "P12" or "PEM" on OpenSSL. The string "P12" or
40"PEM" must be specified with CURLOPT_PROXY_SSLCERTTYPE(3).
41
42If the blob is initialized with the flags member of struct curl_blob set to
43CURL_BLOB_COPY, the application does not have to keep the buffer around after
44setting this.
45
46This option is an alternative to CURLOPT_PROXY_SSLCERT(3) which instead
47expects a filename as input.
