AES-128-ECB - 節點JS和java的不一致加密結果

Question

節點js代碼：

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; 
}

Java代碼：

主要的java：

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

AES的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來解決這個問題， http://nodejs.org/api/crypto.html#crypto_crypto_createcipheriv_algorithm_key_iv

Answer 2

您需要墊字符串"test" 16個字節。我相信Java默認使用PKCS填充（但也有其他填充方案）。

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