chksum-cli

A simple checksum calculator.

Motivation

There are variety of tools that allows calculate hash digests.

However tools like md5sum, sha1sum, b2sum, sha224sum and others offer only file-based checksums.

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

Instead you can just use chksum with preffered hash algorithm.

sh chksum sha2-224 dir/

Features

• Written in pure Rust
• No unsafe code
• Multithread

Use cargo install to install chksum binary in $HOME/.cargo/bin directory.

shell cargo install chksum-cli

Hash algorithms

Implemented hash algorithms:

• MD5 - RFC 1321: The MD5 Message-Digest Algorithm
• SHA-1 - RFC 3174: US Secure Hash Algorithm 1 (SHA1)
• SHA-2 family (SHA-224, SHA-256, SHA-386, SHA-512) - FIPS PUB 180-4: Secure Hash Standard
