6 of 7 as requested by the community, added an online tester to ease the task :D

ncomputers.org/entropyarray performs a faster entropy test than ent with 16, 32, 64, 128, 256 and 512 bits serial correlation tests.

with ncomputers.org/entropy tool, you may also perform visual frequency and distribution tests, plotting the outputs entropy.freq and entropy.gaus

as an example you may perform an online test of up to 32MB using ncomputers.org/entropytest

entropy.freq entropy.gaus
