CURLOPT_SSLKEY(3) | Library Functions Manual | CURLOPT_SSLKEY(3) |
NAME¶
CURLOPT_SSLKEY - private key file 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 filename 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 key-chain 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.
This option works only with the following TLS backends: OpenSSL, Schannel, mbedTLS and wolfSSL
EXAMPLE¶
int main(void) {
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
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");
res = 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.
