ent-rs

ent-rs is a Rust library for analyzing the entropy and randomness characteristics of binary data. It is a Rust port and extension of the functionality from Håkan Blomqvist's ent.hpp.

It is useful for evaluating:

• Compression potential
• Statistical randomness
• Distribution uniformity
• Pseudorandom number generators
• Data quality or obfuscation

Features

• Byte and bit mode entropy analysis
• Chi-square test and p-value
• Arithmetic mean
• Monte Carlo Pi estimation
• Serial correlation
• Value frequency tables

Usage

Add to your Cargo.toml:

ent-rs = "0.1"

Example

use ent_rs::EntStats;
let data = std::fs::read("mydata.bin").unwrap();
let stats = EntStats::from_data(&data, false);
println!("Entropy: {:.4}", stats.entropy);
