Pure-Rust implementation of simple checksum calculator.

chksum

For people who wants to make checksum of whole directory but doesn't like piping.

$ find /path -type f -exec md5sum \{\} + | sort -k1 | md5sum

Synchronous

Enable sync feature during installation.

$ cargo install chksum[sync]

Code example.

use chksum::arch::x1::Arch;
use chksum::hash::md5;
use chksum::prelude::*;

let mut hash = md5::Hash::<Arch>::new();
let digest = "path/to/file".chksum(&mut hash)?;
println!("digest {:x}", digest);

Asynchronous

Enable async feature during installation.

$ cargo install chksum[async]

Code example.

use chksum::arch::x1::Arch;
use chksum::hash::md5;
use chksum::prelude::*;

let mut hash = md5::Hash::<Arch>::new();
let digest = "path/to/file".chksum(&mut hash).await?;
println!("digest {:x}", digest);

Hash algorithms

Currently there are implemented two hash algorithms:

• MD5 - RFC 1321: The MD5 Message-Digest Algorithm
• SHA-1 - RFC 3174: US Secure Hash Algorithm 1 (SHA1)
