Entropy Testing

In order verify that the random package actually generates random enough entropy/data, this test program holds the core functions that generate entropy as well as some noise makers to simulate a running program.

Please also note that output from tickFeeder is never used directly but fed as entropy to the actual RNG - fortuna.

With tickFeeder, to be sure that the delivered entropy is of high enough quality, only 1 bit of entropy is expected per generated byte - ie. we gather 8 times the amount we need. The following test below is run on the raw output.

To test the quality of entropy, first generate random data with the test program:

go build

./test tickfeeder tickfeeder.out 1 # just the additional entropy feed
# OR
./test fortuna fortuna.out 10 # the actual CSPRNG with feeders

Then, run dieharder, a random number generator test tool:

dieharder -a -f output.bin

Below you can find two test outputs of dieharder. Please note that around 5 tests of dieharder normally fail. This is expected and even desired. Also, the rng currently reseeds (ie. adds entropy) after 1MB or 10 minutes.

dieharder of two samples of 10MB of fortuna (with feeders) (go version go1.14.2 linux/amd64 on 21.04.2020):
