Java AES 加密整个字符串 [英] Java AES Encrypt Entire String

问题描述

如何使用 AES 加密整个字符串.我下面的代码只加密到第一个识别的空间:(.我该如何解决这个问题?谢谢

How can I encrypt an entire string with AES. The code that I have below only encrypts up to the first space recognized :(. How can I fix this? Thanks

SecretKeySpec key = new SecretKeySpec(salt.getBytes(), "AES");
    Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding", "SunJCE");
    cipher.init(Cipher.ENCRYPT_MODE, key);
    String result = new String(cipher.doFinal(message.getBytes()));
    System.out.println("Encrypted:" + result);

编辑天哪，我不能相信这一点，我怎么会错过这个:( 因为我的扫描仪正在使用 next 而不是 nextLine ......这让我一整天都很尴尬，直到现在我才真正考虑检查它.问题解决了:) 谢谢大家

EDIT OMG I CANT BELIEVE THIS, HOW COULD I MISS THIS :( ITS BECAUSE MY SCANNER WAS TAKING next instead of nextLine... how embarrassing this bugged me all day and only now did i actually think about checking that. Problem solved :) Thanks everyone

推荐答案

除了尝试使用 new String(字节[]).试试这个尺寸:

I don't see anything wrong with your code except trying to print an arbitrary byte[] using new String(byte[]). Try this on for size:

public static byte[] encrypt(String message) throws Exception
{
    String salt = "1111111111111111";
    SecretKeySpec key = new SecretKeySpec(salt.getBytes(), "AES");
    Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding", "SunJCE");
    cipher.init(Cipher.ENCRYPT_MODE, key);
    return cipher.doFinal(message.getBytes());
}

public static void main (String[] args) throws Exception
{
    String hello = Arrays.toString(encrypt("hello"));
    System.out.println("hello:" + hello);
    String helloWorld = Arrays.toString(encrypt("hello world"));
    System.out.println("hello world:" + helloWorld);
}

打印:

hello:[115, -73, -46, -121, 36, -106, -99, 100, 103, -24, -40, -38, 113, -8, 40, -57]
hello world:[5, 88, -31, 115, 4, 48, -75, 44, 83, 21, 105, -67, 78, -53, -13, -28]

我想我们都同意这是两个不同的字节数组.

I think we can all agree that those are two different byte arrays.
