java php aes加密解密_java和php通用的AES加密解密
AES加密解密就不说了，网上百度一堆。需要注意的是java与php互通要选择AES/CBC/NoPadding
下面还是只接上代码吧package com.zns.crypto;
import org.apache.commons.codec.binary.Base64;
import javax.crypto.BadPaddingException;
import javax.crypto.Cipher;
import javax.crypto.IllegalBlockSizeException;

import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.security.InvalidAlgorithmParameterException;
import java.security.InvalidKeyException;

测试用例：public class Main {
public static void main(String[] args) {
String key = DigestUtils.sha1Hex("123456").substring(0,16);
String iv = "1234567890123456";
String data = "steven11111";
String encryptData = AES.encrypt(key,iv ,data );
System.out.println(encryptData);
String decryptData = AES.decrypt(key,iv,Base64.decodeBase64(encryptData));
System.out.println(decryptData);
}
}
PHP的代码：
crypt方式：
/**
* Created by PhpStorm.
* User: Administrator
* Date: 2017/1/19 0019
* Time: 上午 10:40
*/
class AES
{
/**
* @param $key 加密KEY
* @param $iv 加密向量
* @param $data 需要加密的数据
* @return string
*/
public static function encrypt($key, $iv, $data)
{
/**
* 打开加密
*/
$td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, "", MCRYPT_MODE_CBC, "");
/**
* 初始化加密
*/
mcrypt_generic_init($td, $key, $iv);
/**
* 加密
*/
$encrypted = mcrypt_generic($td, $data);
/**
* 清理加密
*/
mcrypt_generic_deinit($td);
/**
* 关闭
*/
mcrypt_module_close($td);
return base64_encode($encrypted);
}
/**
* @param $key
* @param $iv
* @param $data
* @return string
*/
public static function decrypt($key, $iv, $data)
{
/**
* 打开加密
*/
$td = mcrypt_module_open(MCRYPT_RIJNDAEL_128,"",MCRYPT_MODE_CBC,"");
/**
* 初始化加密
*/
mcrypt_generic_init($td, $key, $iv);
$decode = base64_decode($data);
/**
* 解密
*/
$dencrypted = mdecrypt_generic($td, $decode);
/**
* 清理加密
*/
mcrypt_generic_deinit($td);
/**
* 关闭
*/
mcrypt_module_close($td);
return $dencrypted;
}
}
测试用例：include 'AES.class.php';
$key = substr(sha1("123456"), 0, 16);
$iv = "1234567890123456";
$data = "steven1234567891011121314";
$code = AES::encrypt($key,$iv,$data);
echo $code;
echo PHP_EOL;
echo AES::decrypt($key,$iv,"0IYawS+QIqyPnWvBAwXW7w==");
openssl方式：$open=openssl_encrypt($data,'aes-128-cbc',$key,false,$iv);
echo $open;
echo PHP_EOL;
echo openssl_decrypt($open,'aes-128-cbc',$key,false,$iv);
代码都测试通过了的。大家有什么不同的意见可以给我留言啊。
