AES C#, Java, PHP, Python和Javascript几种语言的AES加密解密实现

c#里面的AES加密解密

在visual studio中写的c#代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;

namespace test
{
    class Class1
    {
        static void Main(string[] args)
        {
            Console.WriteLine("I am comming");
            String source = "Test String";
            String encryptData = Class1.Encrypt(source, "1234567812345678", "1234567812345678");
            Console.WriteLine("=1==");
            Console.WriteLine(encryptData);
            Console.WriteLine("=2==");
            String decryptData = Class1.Decrypt("2fbwW9+8vPId2/foafZq6Q==", "1234567812345678", "1234567812345678");
            Console.WriteLine(decryptData);

            Console.WriteLine("=3==");

            Console.WriteLine("I will go out");
        }

        public static string Encrypt(string toEncrypt, string key, string iv)
        {
            byte[] keyArray = UTF8Encoding.UTF8.GetBytes(key);
            byte[] ivArray = UTF8Encoding.UTF8.GetBytes(iv);
            byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(toEncrypt);
            RijndaelManaged rDel = new RijndaelManaged();
            rDel.Key = keyArray;
            rDel.IV = ivArray;
            rDel.Mode = CipherMode.CBC;
            rDel.Padding = PaddingMode.Zeros;
            ICryptoTransform cTransform = rDel.CreateEncryptor();
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            return Convert.ToBase64String(resultArray, 0, resultArray.Length);
        }

        public static string Decrypt(string toDecrypt, string key, string iv)
        {
            byte[] keyArray = UTF8Encoding.UTF8.GetBytes(key);
            byte[] ivArray = UTF8Encoding.UTF8.GetBytes(iv);
            byte[] toEncryptArray = Convert.FromBase64String(toDecrypt);
            RijndaelManaged rDel = new RijndaelManaged();
            rDel.Key = keyArray;
            rDel.IV = ivArray;
            rDel.Mode = CipherMode.CBC;
            rDel.Padding = PaddingMode.Zeros;
            ICryptoTransform cTransform = rDel.CreateDecryptor();
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            return UTF8Encoding.UTF8.GetString(resultArray);
        }
    }
}

其中加密后以及解密后的字符串都能成功打印，但Console.WriteLine("=3==");之后的输出就没有了，最后输出个线程返回值0，然后就没有然后了。c#不懂，就不深究了，就已执行的部分，是符合要求了。

Java的AES加密解密：

java代码，测试也是可以的

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

import org.junit.Test;

...

    @Test
    public void testCrossLanguageEncrypt() throws Exception{
        System.out.println(encrypt());
        System.out.println(desEncrypt());
    }

    public static String encrypt() throws Exception {
        try {
            String data = "Test String";
            String key = "1234567812345678";
            String iv = "1234567812345678";
            Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
            int blockSize = cipher.getBlockSize();
            byte[] dataBytes = data.getBytes();
            int plaintextLength = dataBytes.length;
            if (plaintextLength % blockSize != 0) {
                plaintextLength = plaintextLength + (blockSize - (plaintextLength % blockSize));
            }
            byte[] plaintext = new byte[plaintextLength];
            System.arraycopy(dataBytes, 0, plaintext, 0, dataBytes.length);

            SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
            IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());
            cipher.init(Cipher.ENCRYPT_MODE, keyspec, ivspec);
            byte[] encrypted = cipher.doFinal(plaintext);
            return new sun.misc.BASE64Encoder().encode(encrypted);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
    public static String desEncrypt() throws Exception {
        try
        {
            String data = "2fbwW9+8vPId2/foafZq6Q==";
            String key = "1234567812345678";
            String iv = "1234567812345678";

            byte[] encrypted1 = new sun.misc.BASE64Decoder().decodeBuffer(data);

            Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
            SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
            IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

            cipher.init(Cipher.DECRYPT_MODE, keyspec, ivspec);
            byte[] original = cipher.doFinal(encrypted1);
            String originalString = new String(original);
            return originalString;
        }
        catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
