CURLOPT_SSLCERT(3) libcurl CURLOPT_SSLCERT(3)
NAME
CURLOPT_SSLCERT - SSL client certificate
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT, char *cert);
DESCRIPTION
Pass a pointer to a null-terminated string as parameter. The string
should be the file name of your client certificate. The default format
is "P12" on Secure Transport and "PEM" on other engines, and can be
changed with CURLOPT_SSLCERTTYPE(3).
With Secure Transport, this can also be the nickname of the certificate
you wish to authenticate with as it is named in the security database.
If you want to use a file from the current directory, please precede it
with "./" prefix, in order to avoid confusion with a nickname.
(Schannel only) Client certificates can be specified by a path expres-
sion to a certificate store. (You can import PFX to a store first). You
can use "<store location>\<store name>\<thumbprint>" to refer to a cer-
tificate in the system certificates store, for example, "Curren-
tUser\MY\934a7ac6f8a5d579285a74fa". The thumbprint is usually a SHA-1
hex string which you can see in certificate details. Following store
locations are supported: CurrentUser, LocalMachine, CurrentService,
Services, CurrentUserGroupPolicy, LocalMachineGroupPolicy, LocalMachi-
neEnterprise. Schannel also support P12 certificate file, with the
string "P12" specified with CURLOPT_SSLCERTTYPE(3).
When using a client certificate, you most likely also need to provide a
private key with CURLOPT_SSLKEY(3).
The application does not have to keep the string around after setting
this option.
DEFAULT
NULL
