About:
Ent is a pseudorandom number sequence test program that subjects sequences to a suite of statistical tests to assess their randomness. It analyzes the distribution of bits and performs tests like the chi-square, entropy, and Monte Carlo Pi calculations to provide a comprehensive quality report. This tool is essential for developers and researchers validating the quality of random number generators.

Key Features:

Chi-square test for distribution uniformity
Entropy calculation for information content
Monte Carlo Pi approximation test
Serial correlation and compression tests

Use Cases:

Validating the statistical quality of custom random number generators
Analyzing the randomness of data streams for cryptographic applications
Testing the output of hardware random number generators

Alternatives:

dieharder – A more comprehensive and modern suite of statistical tests for random number generators.
prngd – A daemon that provides entropy to applications, focusing on generation rather than testing.
