[ncomputers.org/entropy-test](http://ncomputers.org/entropy-test) performs a faster entropy test than `ent` with 16, 32, 64, 128, 256 and 512 bits serial correlation tests.

with [entropy](http://ncomputers.org/entropy) tool, you may also perform visual frequency and distribution tests, plotting the outputs **entropy.freq** and **entropy.gaus**
