NAME

6       CURLOPT_SSLKEY - private keyfile for TLS and SSL client cert
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEY, char *keyfile);
12

DESCRIPTION

14       Pass  a  pointer  to  a null-terminated string as parameter. The string
15       should be the file name of your private  key.  The  default  format  is
16       "PEM" and can be changed with CURLOPT_SSLKEYTYPE(3).
17
18       (Windows,  iOS and Mac OS X) This option is ignored by Secure Transport
19       and Schannel SSL backends because they expect the private key to be al‐
20       ready  present  in the keychain or PKCS#12 file containing the certifi‐
21       cate.
22
23       The application does not have to keep the string around  after  setting
24       this option.
