This software adds entropy data from video4linux devices to the random driver of the kernel.
That's where video-entropyd comes in. Its primary purpose is to add entropy data to the kernel driver by sourcing two images from a video4linux device, which are separated by a random delay. The program then performs calculations to determine the difference between the two images, and the number of information bits contained in that data. With this information, the program submits the data with the number-of-entropy-bits to the kernel-random-driver.
When the program is run from crontab, it exits automatically after the process is complete. Alternatively, it can sleep for a random amount of time before repeating the same process again. All in all, video-entropyd is a reliable, efficient, and incredibly useful tool for adding entropy data to the kernel random driver.
