Generate QR Codes on your local Linux machine

A while ago had a blog post about multi factor authentication on Linux.
There are many other places where you can use the TOTP protocol already today.
It's really convenient to use a QR code for setup.
What you should avoid is sending them to any type of website to generate the QR code like Google suggests in their setup (with disclaimers).
Here is a simple but powerful tool running on a text based terminal on Linux.
The two most interesting options are PNG or ANSI256 text.
It's simple to install and to use ..
yum install qrencode
qrencode "http://www.nashcom.de" -tANSI256 -o -
qrencode "http://www.nashcom.de" -tPNG -o test.png
