How does the trueRand latency timer work?
The trueRand generator attempts to measure entropy from the latency of a user’s keystrokes every time the user types on the keyboard. It is used to generate the initial randseed.bin which is in turn used to seed to X9.17 generator. The quality of the output of trueRand is dependent upon its input. If the input has a low amount of entropy, the output will not be as random as possible. In order to maxmize the entropy, the keypresses should be spaced as randomly as possible.
