Sample data

kura-rs (Rust)scipy.stats.entropy

How kura-rs works

1
Copy the code
Rust parts are plain source files. kura add <name> copies them into your project, and from then on they are yours to read and change.
2
Or install for Python
The same parts are built with PyO3 and published as one package, kura-rs.
3
Keep the proof
Each part lists the reference it was tested against, how many cases passed, and where it gets faster than the reference.

Install

Byte Entropy

cargo install kura-rs
kura add byte-entropy

Usage

Open Byte Entropy

use crate::parts::byte_entropy::windows;

for w in windows(&binary, 4096) {
    if w.entropy > 7.2 {
        println!("offset {:#x}: likely packed ({:.2} bits/byte)", w.offset, w.entropy);
    }
}
