CURLOPT_SSLCERT(3)

NAME

CURLOPT_SSLCERT - set SSL client certificate

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT, char *cert);

DESCRIPTION

Pass a pointer to a zero 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 NSS or 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 must be specified by a path expression to a certificate store. (Loading PFX is not supported; you can import it to a store first). You can use "<store location>\<store name>\<thumbprint>" to refer to a certificate in the system certificates store, for example, "CurrentUser\MY\934a7ac6f8a5d579285a74fa61e19f23ddfe8d7a". 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, LocalMachineEnterprise.

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

PROTOCOLS

  curl_easy_setopt(curl, CURLOPT_SSLKEY, "key.pem");
