Entropy and Randomness Online Tester

This tool is a 16 bits Shannon Entropy calculator also useful to test serial correlation of binary files.

It uses gnuplot to create the frequency and distribution graphs useful for testing normality.

The results help to estimate the strength and quality of random number generators.

Entropy formula measures the equiprobability regardless of real unpredictability.

Real unpredictabiliy is related to the quantum mechanics uncertainty principle.

Randomness is important for encryption and other computing-related fields.
