chksum

High-level interface for easy calculation of checksum digest for files, directories, stdin and more.

Features

Written in pure Rust
Easy to use interface
No unsafe code
Configurable via Cargo features

Setup

Add the following entry to the dependencies section of your Cargo.toml file:

[dependencies]
# ...
chksum = "0.2.2"

Alternatively, you can use the cargo add subcommand:

cargo add chksum

Usage

Use chksum function and File as an input.

use std::fs::File;

use chksum::chksum;
use chksum::hash::SHA2_224;

let file = File::open(path)?;
let digest = chksum::<SHA2_224, _>(file)?;
assert_eq!(
    digest.to_hex_lowercase(),
    "a39b86d838273f5ff4879c26f85e3cb333bb44d73b24f275bad1a6c6"
);

Alternatively use ReadDir as an input.

use std::fs::read_dir;

use chksum::chksum;
use chksum::hash::SHA2_256;

let dir = read_dir(path)?;
let digest = chksum::<SHA2_256, _>(dir)?;
assert_eq!(
    digest.to_hex_lowercase(),
    "5c3bfbc8614adc72d3ec0e9b15a1fd1c55cee63e34af5a4ff058eb2eef7d8482"
);
