Simtec Electronics UDEKEY01 Entropy Key Daemon
This is a driver for the Simtec Electronics Entropy Key. It is
only needed if you have such a device (or devices). It provides
a daemon and tools to drive and control it, as well as options
for injecting entropy directly into the kernel's pool, or serving
it via the EGD protocol.
