php7 aes 对接java aes SHA1PRNG算法

近日项目对接，php对接java接口实现数据的请求。其中由于两种语言的语法及函数用法不同，调试起来比较挠头，网上参考了很多关于加密的文章

php中关于AES加密对应Java中的SHA1PRNG方式加密的实例详 此案例所用的php5的函数居多，对于项目长久来说不利；

废话不多说直接上代码,java代码如下

package com.hcmdonline.util.security;

import java.io.UnsupportedEncodingException;
import java.security.SecureRandom;
import java.util.Base64;

import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;


public class AESUtil {

public static final String DEFAULT_ENCODE = "UTF-8";

/**
 * <p>加密，编码UTF-8</p>
 * @param data 待加密数据
 * @param secretKey 秘钥
 * @return 加密数据
 */
   public static String encrypt(String data, String secretKey){
   	
       String strs = null;
       try {
           byte[] bytes = doAES(Cipher.ENCRYPT_MODE, data.getBytes(), secretKey.getBytes());
           // base64编码字节
           strs = new String(Base64.getEncoder().encode(bytes), DEFAULT_ENCODE);
       } catch (UnsupportedEncodingException e) {
       	throw new RuntimeException(e);
       }
       return strs;
   }

   /**
 * <p>解密，编码UTF-8</p>
 * @param data 待解密数据
 * @param secretKey 秘钥
 * @return 解密数据
 */
   public static String decrypt(String data, String secretKey){
   	
       String strs = null;
       try {
           byte[] src = Base64.getDecoder().decode(data);
           byte[] bytes = doAES(Cipher.DECRYPT_MODE, src, secretKey.getBytes());
           strs = new String(bytes, DEFAULT_ENCODE);
       } catch (UnsupportedEncodingException e) {
       	throw new RuntimeException(e);
       }
       return strs;

   }

   public static byte[] doAES(int mode, byte[] data, byte[] key){
   	
       try{
           KeyGenerator kgen = KeyGenerator.getInstance("AES");
           SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
           random.setSeed(key);
           kgen.init(128, random);
           SecretKey secretKey = kgen.generateKey();
           byte[] enCodeFormat = secretKey.getEncoded();
           SecretKeySpec keySpec = new SecretKeySpec(enCodeFormat,"AES");
           Cipher cipher = Cipher.getInstance("AES");// 创建密码器
           cipher.init(mode, keySpec);// 初始化
           return cipher.doFinal(data);
       }catch (Exception e){
           throw new RuntimeException(e);
       }
   }

   public static void main(String[] args) {
   	
   	String secretKey = "123456";
       String data = "{\"鹅宿池边树\":\"僧踹月下门\"}";
       String encryptData = encrypt(data, secretKey);
       System.out.println("明文是: " + data);
       System.out.println("加密后: " + encryptData);
       System.out.println("解密后：" + decrypt(encryptData, secretKey));
   }
}

php 代码如下

public function encrypt($encrypt) {
       $key = substr(openssl_digest(openssl_digest($this->_secretKey, 'sha1', true), 'sha1', true), 0, 16);
       $decrypted = openssl_encrypt($encrypt, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
       return base64_encode($decrypted);
   }

public function decrypt($decrypt) {
       $key = substr(openssl_digest(openssl_digest($this->_secretKey, 'sha1', true), 'sha1', true), 0, 16);
       $decrypted = openssl_decrypt(base64_decode($decrypt), 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
       return $decrypted;
   }
