README
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);
