使用AES 256 CTR在Node JS中加密，在Golang中解密

const crypto = require('crypto');

function encrypt(text, key, iv) {
  const cipher = crypto.createCipheriv('aes-256-ctr', key, iv);
  let encrypted = cipher.update(text, 'utf8', 'hex');
  encrypted += cipher.final('hex');
  return encrypted;
}

const plaintext = 'Hello, world!';
const key = crypto.randomBytes(32); // 256位密钥
const iv = crypto.randomBytes(16); // 128位初始化向量

const encryptedText = encrypt(plaintext, key, iv);
console.log('Encrypted Text:', encryptedText);

package main

import (
	"crypto/aes"
	"crypto/cipher"
	"encoding/hex"
	"fmt"
)

func decrypt(encryptedText string, key []byte, iv []byte) (string, error) {
	ciphertext, err := hex.DecodeString(encryptedText)
	if err != nil {
		return "", err
	}

	block, err := aes.NewCipher(key)
	if err != nil {
		return "", err
	}

	stream := cipher.NewCTR(block, iv)
	plaintext := make([]byte, len(ciphertext))
	stream.XORKeyStream(plaintext, ciphertext)

	return string(plaintext), nil
}

func main() {
	encryptedText := "e4b7f3c8a5d2"
	key := []byte{ /* 32字节的密钥 */ }
	iv := []byte{ /* 16字节的初始化向量 */ }

	decryptedText, err := decrypt(encryptedText, key, iv)
	if err != nil {
		fmt.Println("Decryption error:", err)
		return
	}

	fmt.Println("Decrypted Text:", decryptedText)
