DESCRIPTION

14       Pass  a  pointer  to  a zero terminated string as parameter. It will be
15       used as the password required to  use  the  CURLOPT_SSLKEY(3)  or  CUR‐
16       LOPT_SSH_PRIVATE_KEYFILE(3)  private  key.   You  never  needed  a pass
17       phrase to load a certificate but you need one to load your private key.
