CURLOPT_SSLKEY (3) Linux Manual Page

CURLOPT_SSLKEY – specify 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 zero 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).

(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.

Default

NULL

Protocols

All TLS based protocols: HTTPS, FTPS, IMAPS, POP3, SMTPS etc.

Example

TODO

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.
