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 \fICURLOPT_SSLKEY(3)\fP is used as an identifier passed to the engine. You have to set the crypto engine with \fICURLOPT_SSLENGINE(3)\fP. \&"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. .SH DEFAULT "PEM" .SH PROTOCOLS All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc. .SH EXAMPLE .nf 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); } .fi .SH AVAILABILITY If built TLS enabled. .SH 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. .SH "SEE ALSO" .BR CURLOPT_SSLKEY "(3), " CURLOPT_SSLCERT "(3), "
