blake256

Go implementation of BLAKE-256 and BLAKE-224 hash functions (SHA-3 candidate).

Install

go get github.com/KarpelesLab/blake256

Usage

package main

import (
	"fmt"

	"github.com/KarpelesLab/blake256"
)

func main() {
	// One-shot hash
	hash := blake256.Sum256([]byte("hello"))
	fmt.Printf("%x\n", hash)

	// Streaming hash
	h := blake256.New()
	h.Write([]byte("hello"))
	fmt.Printf("%x\n", h.Sum(nil))

	// With salt (16 bytes)
	h, err := blake256.NewSalt([]byte("0123456789abcdef"))
	if err != nil {
		panic(err)
	}
	h.Write([]byte("hello"))
	fmt.Printf("%x\n", h.Sum(nil))
}

BLAKE-224

hash := blake256.Sum224([]byte("hello"))
h := blake256.New224()

Features

• BLAKE-256 and BLAKE-224 hash computation
• Implements hash.Hash, encoding.BinaryMarshaler, and encoding.BinaryUnmarshaler
• Optional 16-byte salt support via NewSalt / New224Salt
• Zero external dependencies
