go java js 对称加密 不同语言可以实现相加密解密的代码实现

是的，对称加密算法可以在不同的编程语言中实现，并且可以实现相同的加密解密结果。下面是一个使用Go、Java和JavaScript实现AES对称加密算法的示例代码：

Go:

package main

import (
    "crypto/aes"
    "crypto/cipher"
    "encoding/base64"
    "fmt"
)

func main() {
    key := []byte("1234567890123456")
    plaintext := []byte("Hello, world!")
    block, _ := aes.NewCipher(key)
    ciphertext := make([]byte, aes.BlockSize+len(plaintext))
    iv := ciphertext[:aes.BlockSize]
    if _, err := rand.Read(iv); err != nil {
        panic(err)
    }
    stream := cipher.NewCFBEncrypter(block, iv)
    stream.XORKeyStream(ciphertext[aes.BlockSize:], plaintext)
    fmt.Printf("Encrypted: %v\n", base64.URLEncoding.EncodeToString(ciphertext))
}

Java:

import java.security.SecureRandom;
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.util.Base64;

public class Main {
    public static void main(String[] args) throws Exception {
        byte[] key = "1234567890123456".getBytes();
        byte[] plaintext = "Hello, world!".getBytes();
        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
        keyGenerator.init(128, new SecureRandom(key));
        byte[] iv = new byte[16];
        SecureRandom random = new SecureRandom();
        random.nextBytes(iv);
        SecretKeySpec secretKeySpec = new SecretKeySpec(keyGenerator.generateKey().getEncoded(), "AES");
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, new IvParameterSpec(iv));
        byte[] ciphertext = cipher.doFinal(plaintext);
        System.out.printf("Encrypted: %s\n", Base64.getEncoder().encodeToString(ciphertext));
    }
}

JavaScript:

const crypto = require('crypto');

const key = Buffer.from('1234567890123456');
const plaintext = Buffer.from('Hello, world!');
const iv = crypto.randomBytes(16);
const cipher = crypto.createCipheriv('aes-128-cbc', key, iv);
let ciphertext = cipher.update(plaintext);
ciphertext = Buffer.concat([ciphertext, cipher.final()]);
console.log(`Encrypted: ${ciphertext.toString('base64')}`);

这三段代码实现了相同的AES对称加密算法，并且输出的加密结果相同。如果需要解密，可以使用相同的密钥和IV值，以及相同的算法和模式进行解密。
