关于AES加密方式在win和linux 下面加密结果值不同，解决

AES加密方式在win和linux 下面加密结果值不同

关于值为什么不同，原因是底层调用了Java 代码 native（）那个方法。所以在不同的系统上加密后的值也就不同了。

解决办法：

下面例子本人亲测可以正常使用:

package com.example.bwjf.demo.util;

import com.sun.org.apache.xerces.internal.impl.dv.util.Base64;
import java.security.SecureRandom;
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.util.StringUtils;

public class AESutil
{
  private static final Logger log = LoggerFactory.getLogger(AESutil.class);
  
  public static String encrypt(String content, String secureKey)
  {
    try
    {
      if ((StringUtils.isEmpty(content)) || 
        (StringUtils.isEmpty(secureKey))) {
        return null;
      }
      KeyGenerator kgen = KeyGenerator.getInstance("AES");
      
      SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
      secureRandom.setSeed(secureKey.getBytes());
      kgen.init(128, secureRandom);
      SecretKey secretKey = kgen.generateKey();
      byte[] enCodeFormat = secretKey.getEncoded();
      SecretKeySpec key = new SecretKeySpec(enCodeFormat, "AES");
      Cipher cipher = Cipher.getInstance("AES");
      byte[] byteContent = content.getBytes("utf-8");
      cipher.init(1, key);
      byte[] result = cipher.doFinal(byteContent);
      return encodeBASE64(result);
    }
    catch (Exception e)
    {
      log.error("��������.", e);
    }
    return null;
  }
  
  public static String decrypt(String content, String secureKey)
  {
    try
    {
      if ((StringUtils.isEmpty(content)) || (StringUtils.isEmpty(secureKey))) {
        return null;
      }
      KeyGenerator kgen = KeyGenerator.getInstance("AES");
      SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
      secureRandom.setSeed(secureKey.getBytes());
      kgen.init(128, secureRandom);
      SecretKey secretKey = kgen.generateKey();
      byte[] enCodeFormat = secretKey.getEncoded();
      SecretKeySpec key = new SecretKeySpec(enCodeFormat, "AES");
      Cipher cipher = Cipher.getInstance("AES");
      cipher.init(2, key);
      byte[] base64Dec = Base64.decode(content);
      byte[] result = cipher.doFinal(base64Dec);
      return new String(result);
    }
    catch (Exception e)
    {
      log.warn("��������,����������:{}", e);
    }
    return null;
  }
  
  public static String encodeBASE64(byte[] content)
    throws Exception
  {
    if ((content == null) || (content.length == 0)) {
      return null;
    }
    try
    {
      return Base64.encode(content);
    }
    catch (Exception e)
    {
      log.error("Base64 encode error.", e);
    }
    return null;
  }
}
