hp blade server

During locfg.pl execution in ubuntu 16.04 how this perl script get the SSL key and certificate file. 

Basically I want to execute 

locfg.pl -f Insert_Virtual_Media.xml -u user -p pass -s IP_of_ILO

But the locfg.pl script gives failure during the creation of socket. I.e., due to the execution of below line. 

$socket = IO::Socket::SSL->new(PeerAddr => $server) || die $ConnectionErrorMessage;

The exact error at the client is: "ERROR: SSL connection error."

How the client knows the SSL key and SSL certificate??

Kindly let me know.

Thanks in advance
