hsh

Simple file hash digests and file integrity checks

Documentation: https://chrissimpkins.github.io/hsh/

About

hsh is a cross-platform command line application that generates file hash digests and performs file integrity checks via file hash digest comparisons. It supports the following hash algorithms:

• MD5
• SHA1
• SHA224
• SHA256
• SHA384
• SHA512

Examples of hsh Features

File Hash Digests

Default File Hash Digests (SHA256)

$ hsh somefile.txt
SHA256 (somefile.txt) :
5c2b47648ae96e60b5d02c573aefa6b01fb49d1b9e1ebd8a1b1a794cf522e6e3

Other Algorithms Available with a Command

$ hsh sha1 somefile.txt
SHA1 (somefile.txt) :
0e1fb609e951c85e01f4048f01f0b51256bb3917

File Integrity Checks

File to File Comparisons

$ hsh firstfile.txt secondfile.txt

SHA256 (firstfile.txt) :
0dbe4bb7df0f6d271e8f1fc30ec586fdfb5218e5a615c9abd3843943b4779e9e
SHA256 (secondfile.txt) :
0dbe4bb7df0f6d271e8f1fc30ec586fdfb5218e5a615c9abd3843943b4779e9e

The hash digests are identical.

File to Hash Digest Comparisons

Include one of the supported file hash digest types as an argument and hsh automatically detects the hash algorithm and performs the test with your file:

$ hsh firstfile.txt 0e1fb609e951c85e01f4048f01f0b51256bb3917

SHA1 (firstfile.txt) :
0e1fb609e951c85e01f4048f01f0b51256bb3917
SHA1 (test) :
0e1fb609e951c85e01f4048f01f0b51256bb3917

The hash digests are identical.

Hash Digest to Hash Digest Comparisons

$ hsh da24f4932321286ac849f9145707f0e8 da24f4932321286ac849f9145707f0e9

da24f4932321286ac849f9145707f0e8
da24f4932321286ac849f9145707f0e9
===============================^

The hash digests are NOT identical.

A diff indicator is displayed below the hash digests when they differ.
