gohash

name	gohash
description	Use this skill when the user wants to calculate file hashes, encode/decode data, or work with cryptographic operations.

gohash Plugin

Command line tools and library to work with hashes and various encodings. Calculate hashes and encode/decode data.

Commands

Hash Calculation

• gohash calculate hash — Calculate hash from stdin or files

Utility

• gohash _ _ — Passthrough to hasher CLI

Usage Examples

• "Calculate SHA256 of this file"
• "Get MD5 hash"
• "Encode to base64"
• "List supported hash algorithms"

Installation

go install github.com/martinlindhe/gohash/cmd/hasher@latest

Examples

# Calculate hash of file
gohash calculate hash file.txt

# List supported hashes
gohash calculate hash --list-hashes

# Calculate SHA256
gohash calculate hash --encoding=sha256 file.txt

# Calculate MD5
gohash calculate hash --encoding=md5 file.txt

# From stdin
cat file.txt | gohash calculate hash

# Any hasher command with passthrough
gohash _ _ --list-hashes
gohash _ _ --encoding=sha256 file.txt

Key Features

• Multiple algorithms - MD5, SHA1, SHA256, SHA512, and more
• Encodings - base64, hex, and more
• File support - Hash files or stdin
• Fast - Efficient Go implementation
• Library - Can be used as Go package
• Cross-platform - Works everywhere
• Extensible - Many hash types supported

Included Tools

• hasher - Calculate hashes
• coder - Encode/decode between formats
• findhash - Search for plaintext matching hashes

Notes

• Default hash algorithm is SHA256
• Use --list-hashes to see all options
• Use --list-encodings for encoding options
• Great for file verification
• Can be used in security workflows
