This program suports both certification and cryptogoraphic with using SSL.

If you do not have certification (/usr/local/openssl/certs/telnet.pem) provided
by CA, this port make dummy certification. Of cource it is useless to certify
but you can use SSL telnet/telnetd in encryption only mode with it.

You must edit /etc/inetd.conf to make SSL telnetd available. Some examples
below:

1. Accept both normal telnet client and SSL telnet client.

telnet	stream	tcp	nowait	root	/usr/local/libexec/telnetd	telnetd 

2. Accpet only SSL encrypted client.

telnet	stream	tcp	nowait	root	/usr/local/libexec/telnetd	telnetd -z secure

3. Accept only SSL certificated client.

telnet	stream	tcp	nowait	root	/usr/local/libexec/telnetd	telnetd -a valid
