Description-en: telnet client with SSL encryption support
The telnet command is used for interactive communication with another host
using the TELNET protocol.
.
SSL telnet replaces normal telnet using SSL authentication and
encryption. It interoperates with normal telnetd in both directions.
It checks if the other side is also talking SSL, if not it falls back
to normal telnet protocol.
.
Advantages over normal telnet: Your passwords and the data you send
will not go in cleartext over the line. Nobody can get it with
tcpdump or similar tools. With SSLtelnet you can also connect to
https-server like https://www.mozilla.org. Just do
'telnet -z ssl www.mozilla.org 443'
