video_entropyd

For security reasons (when doing network traffic or generating secure keys for example) one wants as much Entropy-data in the kernel random-driver as possible. The random-driver takes partially care for this. But in situations in where there`s a lot of demand for entropy-data, it might not be able to gather enough entropy-data by itself.That`s where this program is for: adding entropy-data to the kernel-driver. It does that by fetching 2 images from a video4linux-device (with a random delay in Between), calculating the difference between those two and then calculating the number of information-bits in that data. After that, the data with the number-of-entropy-bits is submitted to the kernel-random-driver.
