🔐 hash-check-cli

A zero-dependency CLI tool for computing and verifying file hashes. Supports MD5, SHA1, SHA256, and SHA512 with batch processing and multiple output formats.

Install

npm install -g hash-check-cli

Usage

# Compute SHA256 of a file (default)
hash-check file.zip

# Use a specific algorithm
hash-check file.iso -a md5
hash-check file.bin -a sha512

# Compute all supported algorithms at once
hash-check -A document.pdf

# Batch process multiple files
hash-check *.tar.gz

# Verify a hash
hash-check file.zip --verify "d41d8cd98f00b204e9800998ecf8427e"

# Write hashes to a file
hash-check *.dmg -o checksums.md5

# sha256sum-compatible output
hash-check *.tar.gz --sha256sum -o sha256sums.txt

Examples

# Single file
$ hash-check ubuntu-24.04.iso
  SHA256    a1b2c3d4e5f6...  ubuntu-24.04.iso

# All hashes
$ hash-check -A important.pdf

# Verification
$ hash-check file.zip -v a1b2c3d4e5f6a7b8...
  ✅ file.zip: SHA256 hash MATCHES

# Batch output
$ hash-check *.txt -o hashes.txt
  SHA256    123abc...  readme.txt
  SHA256    def789...  notes.txt
  Hash file written: hashes.txt

Options

| Option | Alias | Description | |--------|-------|-------------| | --algorithm <algo> | -a | Hash algorithm: md5, sha1, sha256, sha512 (default: sha256) | | --all | -A | Compute all supported algorithms | | --verify <hash> | -v | Verify a hash against the file | | --output <file> | -o | Write hashes to a file | | --sha256sum | | Output in sha256sum-compatible format | | --json | -j | JSON output | | --help | -h | Show help |

Features

• ✅ Pure Node.js — uses built-in crypto module, zero dependencies
• ✅ Multiple algorithms — MD5, SHA1, SHA256, SHA512
• ✅ Batch processing — glob patterns for multiple files
• ✅ Hash verification — check a file against an expected hash
• ✅ Output to file — save checksums in standard or sha256sum format
• ✅ JSON output — machine-readable format for scripting
• ✅ File size display — shown alongside hashes in verbose mode
