allsum

allsum

allsum is a command-line utility written in Go that computes cryptographic checksums and hashes using a wide range of algorithms. It supports output in multiple formats and can process files or standard input.

Features

• Supports over 25 hashing algorithms including SHA, BLAKE, CRC, MD, RIPEMD, Whirlpool, and Streebog.
• Output formats: GNU-style, BSD-style, JSON, YAML.
• Supports checksum generation from files or standard input.
• Outputs to file or stdout.
• Prevents overwriting unless forced.
• Easy to script and automate.

Supported Algorithms

• adler32
• blake2b
• blake2s
• blake3
• crc32_Castagnoli
• crc32_IEEE
• crc32_Koopman
• crc64_ECMA
• crc64_ISO
• md4
• md5
• ripemd160
• sha1
• sha224
• sha256
• sha3-224
• sha3-256
• sha3-384
• sha3-512
• sha384
• sha512
• sha512/224
• sha512/256
• streebog256
• streebog512
• whirlpool

Installation

Standard

go install github.com/andyhedges/allsum

Locally

git clone https://github.com/andyhedges/allsum.git
cd allsum
go build -o allsum main.go

This will create the allsum executable in the current directory.

Usage

allsum [OPTIONS] [FILE]...

If no file is provided or - is specified, input is read from standard input.

Options

Examples

Generate all checksums in default GNU format for example.txt:

./allsum -alg all example.txt

Use specific algorithms (e.g., SHA256 and BLAKE3):

./allsum -alg sha256,blake3 example.txt

Output to stdout in YAML format:

./allsum -alg sha3-512 -format yaml -stdout example.txt

Generate checksums from standard input:

cat file.bin | ./allsum -alg md5 -

List all supported algorithms in JSON format:

./allsum -l -format json

allsum is a helpful tool for generating file integrity checks in multiple formats using many popular (and some less common) hash algorithms. Great for backup verification, forensic tools, or scripting!

Docker

You can build and run allsum using Docker for a fully isolated environment.

Build Docker Image

docker build -t allsum .

Run allsum in Docker

To run allsum and pass a file from your local system:

docker run --rm -v $(pwd):/data allsum -alg sha256 /data/yourfile.txt

Run with Standard Input

cat yourfile.txt | docker run --rm -i allsum -alg md5 -

This will execute allsum inside the Docker container using standard input.
