CURLOPT_SSLKEY(3) | curl_easy_setopt options | CURLOPT_SSLKEY(3) |
NAME¶
CURLOPT_SSLKEY - private keyfile for TLS and SSL client cert
SYNOPSIS¶
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEY, char *keyfile);
DESCRIPTION¶
Pass a pointer to a null-terminated string as parameter. The string should be the file name of your private key. The default format is "PEM" and can be changed with CURLOPT_SSLKEYTYPE(3).
(Windows, iOS and Mac OS X) This option is ignored by Secure Transport and Schannel SSL backends because they expect 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.
DEFAULT¶
NULL
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_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.
