CURLOPT_SSLKEYTYPE(3)      curl_easy_setopt options      CURLOPT_SSLKEYTYPE(3)

NAME
       CURLOPT_SSLKEYTYPE - set type of the private key file

SYNOPSIS
       #include <curl/curl.h>

       CURLcode   curl_easy_setopt(CURL   *handle,   CURLOPT_SSLKEYTYPE,  char
       *type);

DESCRIPTION
       Pass a pointer to a zero terminated string  as  parameter.  The  string
       should  be the format of your private key. Supported formats are "PEM",
       "DER" and "ENG".

       The format "ENG" enables you to load the  private  key  from  a  crypto
       engine.  In this case CURLOPT_SSLKEY(3) is used as an identifier passed
       to  the  engine.  You  have  to  set  the  crypto  engine   with   CUR-
       LOPT_SSLENGINE(3).   "DER"  format  key  file  currently  does not work
       because of a bug in OpenSSL.

       The application does not have to keep the string around  after  setting
       this option.

DEFAULT
       "PEM"

PROTOCOLS
       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, 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.
