我正在尝试在 Python 程序中加密一些数据并将其保存，然后在 Java 程序中解密该数据。在Python中，我像这样加密它：
from Crypto.Cipher import AES
KEY = '12345678901234567890123456789012'
def encrypt(data):
cipher = AES.new(KEY, AES.MODE_CFB)
return cipher.encrypt(data)
在 Java 中，我像这样解密它：
import java.security.*;
import javax.crypto.*;
import javax.crypto.spec.SecretKeySpec;
public class Encryption {
private static byte[] KEY = { '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', '1', '2', '3', '4', '5', '6', '7',
'8', '9', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', '1', '2' };
public static byte[] decrypt(byte[] data) throws NoSuchAlgorithmException, NoSuchPaddingException,
InvalidKeyException, IllegalBlockSizeException, BadPaddingException {
Cipher c = Cipher.getInstance("AES/CFB/NoPadding");
Key key = new SecretKeySpec(KEY, "AES");
c.init(Cipher.DECRYPT_MODE, key);
return c.doFinal(data);
}
}
但我得到Exception in thread "main" java.security.InvalidKeyException: Illegal key size or default parameters。显然，我做错了什么。但什么？
