CURLOPT_SSLKEYTYPE(3) curl_easy_setopt options CURLOPT_SSLKEYTYPE(3)
NAME
CURLOPT_SSLKEYTYPE - type of the private key file
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEYTYPE, char *type);
DESCRIPTION
Pass a pointer to a null-terminated string as parameter. The string
should be the format of your private key. Supported formats are "PEM",
"DER" and "ENG".
The format "ENG" enables you to load the private key from a crypto en-
gine. In this case CURLOPT_SSLKEY(3) is used as an identifier passed to
the engine. You have to set the crypto engine with CUR-
LOPT_SSLENGINE(3). "DER" format key file currently does not work be-
cause of a bug in OpenSSL.
The application does not have to keep the string around after setting
this option.
DEFAULT
"PEM"
PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_SSLCERT, "client.pem");
curl_easy_setopt(curl, CURLOPT_SSLKEY, "key.pem");
curl_easy_setopt(curl, CURLOPT_SSLKEYTYPE, "PEM");
curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITY
If built TLS enabled.
RETURN VALUE
Returns CURLE_OK if TLS is supported, CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
