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 > output.bin # just the additional entropy feed
# OR
./test fortuna > output.bin # the actual CSPRNG
ls -lah output.bin # check filesize: should be ~1MB
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.
