hyperhash

A fast, parallel file hashing utility with support for multiple hash algorithms and verification capabilities. Compatible with standard hashing tools like sha256sum, md5sum, and similar utilities.

Features

• Parallel processing: Multi-threaded hashing for improved performance on multi-core systems
• Glob pattern support: Use wildcards to match files (e.g., *.txt, **/*.go)
• Standard compatibility: Output format compatible with sha256sum, md5sum, and other standard tools

Installation

go install github.com/indrora/hyperhash@latest

Or clone and build locally:

git clone https://github.com/indrora/hyperhash.git
cd hyperhash
go build

Usage

Usage: hyperhash [options] <file1> <file2> ...
Options:
  -h, --help          Show help message
  -p, --progress      Show progress bars
  -q, --quiet         Do not print any non-error output
  -t, --type string   The type of hash to compute (e.g., sha256, md5) (default "sha256")
  -v, --verbose       Enable verbose output
  -c, --verify        Verify the computed hashes against existing hash values
      --workers int   Number of worker goroutines to use (default is number of CPU cores)

Sum using the default (SHA256)

hyperhash [-t <type>] <filespec> [<filespec> ...]

Verify a hash file.

hyperhash -t <type> -c <hashfile> [<hashfile> ...]

I'll let this speak for itself.
