# Plaintext for randomness evaluation of cryptographic algorithms?

I’m running an experiment to test the randomness output of many cryptographic algorithms based on INST test suite to measure the randomness of their outcome.

However I’m searching to a sample data set to perform the experiment. Based on my understanding the data set should be non-random to be able to measure the randomness after applying the cryptographic algorithm.

What plaintext should I use for this?

• I replaced your (off-topic) link request with a question that should be equally helpful. – otus Jul 9 '16 at 6:35

• E.g. by using dd and /dev/null together. I could also program it in Java within seconds. – Maarten Bodewes Jul 9 '16 at 14:52
