Pass a pointer to a zero terminated string as parameter. It will be used as the password required to use the \fICURLOPT_PROXY_SSLKEY(3)\fP private key. You never needed a pass phrase to load a certificate but you need one to load your private key. The application does not have to keep the string around after setting this option. .SH DEFAULT NULL .SH PROTOCOLS Used with HTTPS proxy .SH EXAMPLE .nf CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/foo.bin"); curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy:443"); curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "superman"); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); } .fi .SH AVAILABILITY Added in 7.52.0 .SH RETURN VALUE Returns CURLE_OK if TLS enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space. .SH "SEE ALSO" .BR CURLOPT_PROXY_SSLKEY "(3), " CURLOPT_SSH_PRIVATE_KEYFILE "(3), " .BR CURLOPT_SSLKEY "(3), "
