Entropy Monitor

In computing, entropy is the randomness collected by an operating system or application for use in cryptography or other uses that require random data. This randomness is often collected from hardware sources, either pre-existing ones such as mouse movements or specially provided randomness generators.

Examples for applications that depend on entropy (random numbers) would be the fortune(6) program, which gives a
random quote, or the solitaire
card game, or the shuffle option in a music player. Without random numbers
these programs would generate the same results every time they run.

High security uses for entropy would be applications that create cryptographic keys.
Even after the key is eventually replaced, everything it was used to encrypt remains
only as safe as the entropy used to generate the key.

This monitor checks the amount of available entropy and informs the system adminstrator about possible bottlenecks on his system.
