节点。JSJavaScript等价于JavaAES+SecretKeySpec解密
下面是我的java代码,我正试图转移到NodeJS
public static String decryptDataWithKey(String keyString, String base64String) throws Exception {
//Algorithm
String AES_ALGORITHM = "AES";
//Key from keystring
MessageDigest digester = MessageDigest.getInstance("MD5");
digester.update(keyString.getBytes());
byte[] password = digester.digest();
Key key = new SecretKeySpec(password, AES_ALGORITHM); // what is the equivalent of this line in javascript ?
//Create decipher
Cipher c = Cipher.getInstance(AES_ALGORITHM);
c.init(Cipher.DECRYPT_MODE, key);
//Get bytes of enc data
byte[] decodedValue = new BASE64Decoder().decodeBuffer(base64String);
// Do decrypt
byte[] decValue = c.doFinal(decodedValue);
String decryptedValue = new String(decValue);
return decryptedValue;
}
我最后写了下面的方法,但得到了异常——糟糕的解密
function decryptDataWithKey(keyString, base64String){
//Algorithm
let algorithm = 'aes-128-ecb';
//Key from keystring
let key = crypto.createHash('md5').update(keyString).digest();
//Create decipher
let decipher = crypto.createDecipher(algorithm,key);
//Get bytes of enc data
let cipher = new Buffer(base64String, 'base64');
// Do decrypt
let decrypted = decipher.update(cipher, 'base64', 'utf-8');
decrypted += decipher.final('utf-8'); // throwing exception : digital envelope routines:EVP_DecryptFinal_ex:bad decrypt
return decrypted;
}
请引导我这里缺少什么。我试图在我的nodejs项目中避免jar依赖。我相信这应该可以通过加密实现。 还是我应该选择crypto js
