aria-go

Go implementation of the ARIA encryption algorithm.

Installation

go get -u github.com/hallazzang/aria-go

Usage

This package is compatible with the standard crypto package.

package main

import (
	"fmt"

	"github.com/hallazzang/aria-go"
)

func main() {
	key := []byte("0123456789abcdef")
	plaintext := []byte("fedcba9876543210")

	block, err := aria.NewCipher(key)
	if err != nil {
		panic(err)
	}

	fmt.Printf("plaintext: %s\n", plaintext)

	ciphertext := make([]byte, 16)
	block.Encrypt(ciphertext, plaintext)
	fmt.Printf("ciphertext: % x\n", ciphertext)

	decrypted := make([]byte, 16)
	block.Decrypt(decrypted, ciphertext)
	fmt.Printf("decrypted: %s\n", decrypted)
}

This will print out:

plaintext: fedcba9876543210
ciphertext: 93 52 1e f2 67 65 0b d1 fc 75 20 5a d3 44 4d 9d
decrypted: fedcba9876543210
