CURLOPT_SSLCERT(3) curl_easy_setopt options CURLOPT_SSLCERT(3) NAME CURLOPT_SSLCERT - SSL client certificate SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT, char *cert); DESCRIPTION Pass a pointer to a null-terminated string as parameter. The string should be the file name of your client certificate. The default format is "P12" on Secure Transport and "PEM" on other engines, and can be changed with CURLOPT_SSLCERTTYPE(3). With NSS or Secure Transport, this can also be the nickname of the cer- tificate you wish to authenticate with as it is named in the security database. If you want to use a file from the current directory, please precede it with "./" prefix, in order to avoid confusion with a nick- name. (Schannel only) Client certificates can be specified by a path expres- sion to a certificate store. (You can import PFX to a store first). You can use "<store location>\<store name>\<thumbprint>" to refer to a cer- tificate in the system certificates store, for example, "Curren- tUser\MY\934a7ac6f8a5d579285a74fa61e19f23ddfe8d7a". Thumbprint is usu- ally a SHA-1 hex string which you can see in certificate details. Fol- lowing store locations are supported: CurrentUser, LocalMachine, Cur- rentService, Services, CurrentUserGroupPolicy, LocalMachineGroupPolicy, LocalMachineEnterprise. Schannel also support P12 certificate file, with the string "P12" specified with CURLOPT_SSLCERTTYPE(3). When using a client certificate, you most likely also need to provide a private key with CURLOPT_SSLKEY(3). 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 enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
