Script for generating HOTP/TOTP keys (and QR code)
Description
This script creates appropriate keys and QR codes for setting up custom
tokens. It can create TOTP (time based) and HOTP (event based) tokens,
and provide textmode QR codes for loading into Google Authenticator. It
can also provide the needed commands to prepare a Yubikey.
Only use this on a trusted system with an encrypted filesystem. This
script was not designed to be used except by experienced users, so it is
not terribly user friendly.
