Question

节点js代码：

function AES_encrypt(){

  var bKey = new Buffer('24Qn9974h50D9DNi', 'utf-8');

  var bInput = new Buffer(‘test’, 'utf-8');

  console.log(bKey.length);

  var cipher = crypto.createCipher('AES-128-ECB',bKey);

  //cipher.setAutoPadding(auto_padding=false);

  var crypted = cipher.update(bInput,null,'base64');

  crypted+=cipher.final('base64');

  console.log(crypted);

  return crypted;
}

获得结果：57b6b7oulw7eO5h7efZ9 / w ==

java代码：

main java：

String data = AES.encryptToBase64("test","24Qn9974h50D9DNi");

AES java：

public static String encryptToBase64(String data, String key){
    try {
        byte[] valueByte = encrypt(data.getBytes("utf-8"), key.getBytes("utf-8");
        return new String(Base64.encode(valueByte));
    } catch (UnsupportedEncodingException e) {
        throw new RuntimeException("encrypt fail!", e);
    }

}

 public static byte[] encrypt(byte[] data, byte[] key) {

    if(key.length!=16){
        throw new RuntimeException("Invalid AES key length (must be 16 bytes)");
    }
    try {
        SecretKeySpec secretKey = new SecretKeySpec(key, "AES"); 
        byte[] enCodeFormat = secretKey.getEncoded();
        SecretKeySpec seckey = new SecretKeySpec(enCodeFormat,"AES");
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, seckey);// 初始化
        byte[] result = cipher.doFinal(data);
        return result; // 加密
    } catch (Exception e){
        throw new RuntimeException("encrypt fail!", e);
    }
}

Answer 1

使用crypto.createCipheriv解决问题， http://nodejs.org/api/crypto.html#crypto_crypto_createcipheriv_algorithm_key_iv

Answer 2

您需要将字符串"test"填充到16个字节。我相信Java默认使用PKCS填充（但也有其他填充方案）。

String data = AES.encryptToBase64("test","24Qn9974h50D9DNi");

AES-128-ECB - 节点js和java的加密结果不一致
