26 CURLOPT_SSLKEY \- specify private keyfile for TLS and SSL client cert
28 #include <curl/curl.h>
30 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEY, char *keyfile);
32 Pass a pointer to a zero terminated string as parameter. The string should be
33 the file name of your private key. The default format is "PEM" and can be
34 changed with \fICURLOPT_SSLKEYTYPE(3)\fP.
36 (iOS and Mac OS X only) This option is ignored if curl was built against
37 Secure Transport. Secure Transport expects the private key to be already
38 present in the keychain or PKCS#12 file containing the certificate.
40 The application does not have to keep the string around after setting this
45 All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
