.SH NAME
|
||
|
|
CURLOPT_SSLKEY \- private key file for TLS and SSL client cert
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEY, char *keyfile);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a pointer to a null\-terminated string as parameter. The string should be
|
||
|
|
the filename of your private key. The default format is "PEM" and can be
|
||
|
|
changed with \fICURLOPT_SSLKEYTYPE(3)\fP.
|
||
|
|
|
||
|
|
(Windows, iOS and macOS) This option is ignored by Secure Transport and
|
||
|
|
Schannel SSL backends because they expect the private key to be already present
|
||
|
|
in the key\-chain or PKCS#12 file containing the certificate.
|
||
|
|
|
||
|
|
The application does not have to keep the string around after setting this
|
||
|
|
option.
|
||
|
|
|
||
|
|
Using this option multiple times makes the last set string override the
|
||
|
|
previous ones. Set it to NULL to disable its use again.
|
||
|
|
.SH DEFAULT
|
||
|
|
NULL
|
||
|
|
.SH PROTOCOLS
|
||
|
|
This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
||
|
|
|
||
|
|
This option works only with the following TLS backends:
|
||
|
|
OpenSSL, Schannel, mbedTLS and wolfSSL
|
||
|
