Ever wanted to use nc for connections over SSL (like HTTPS)? Well it won't work. You need to use different tools such as openssl sclient or socat. To me these tools have strange cmd line options, so I ended up with a really simple netcat utility which speaks SSL/TLS to the server.
$ usage: nc-ssl [options] <host> <service>
$ options:
$ -d: enable debug output
$ -v: verify host's certificate
$ -2: use SSL version 2
$ -3: use SSL version 3
$ nc-ssl www.google.de https
GET / HTTP/1.1
Host: www.google.de
Connection: Close
HTTP/1.1 200 OK
