+.SH NAME
+CURLOPT_PROXY_SSLKEY \- specify private keyfile for TLS and SSL proxy client cert
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLKEY, char *keyfile);
+.SH DESCRIPTION
+Pass a pointer to a zero terminated string as parameter. The string should be
+the file name of your private key used for connecting to the HTTPS proxy. The
+default format is "PEM" and can be changed with
+\fICURLOPT_PROXY_SSLKEYTYPE(3)\fP.
+
+(iOS and Mac OS X only) This option is ignored if curl was built against
+Secure Transport. Secure Transport expects the private key to be already
+present in the keychain or PKCS#12 file containing the certificate.
+
+The application does not have to keep the string around after setting this
+option.
