chksum-cli

A simple checksum calculator.

Motivation

Various tools like md5sum, sha1sum, b2sum, sha224sum, etc., allow users to calculate file-based hash digests. However, these tools focus on file-level checksums, making it cumbersome to handle scenarios like calculating digests of whole directories. This motivated the creation of chksum to offer a simplified interface for such use cases.

find dir/ -type f | sort | xargs cat | sha224sum

With chksum, you can achieve the same result with your preferred hash algorithm:

chksum sha2-224 dir/

Key Features

• Implemented in pure Rust
• No unsafe code
• Configurable via Cargo features
• Multithreaded

Installation

Install the chksum binary using cargo install:

cargo install chksum-cli
