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 engine. 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 because 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.
