AES加密解密 PHP+JAVA互通

1:php 加密

<?php
declare(strict_types=1);

namespace App\Constants;

class Security {
    /**
     *
     * @param string $string 需要加密的字符串
     * @param string $key 密钥
     * @return string
     */
    public static function encrypt($string, $key)
    {
        $key = substr(openssl_digest(openssl_digest($key, 'sha1', true), 'sha1', true), 0, 16);
        // openssl_encrypt 加密不同Mcrypt，对秘钥长度要求，超出16加密结果不变
        $data = openssl_encrypt($string, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
        $data = base64_encode($data);
        return $data;
    }

    /**
     * @param string $string 需要解密的字符串
     * @param string $key 密钥
     * @return string
     */
    public static function decrypt($string, $key)
    {
        $key       = substr(openssl_digest(openssl_digest($key, 'sha1', true), 'sha1', true), 0, 16);
        $encrypted = base64_decode($string);
        return openssl_decrypt($encrypted, 'aes-128-ecb', $key, OPENSSL_RAW_DATA);
    }

}

 

使用

$key = "root:123456789as";
$pass = Security::encrypt("123456", $key);
print_r($pass);
//pvHHE4r31k0yC82me2bi0A==
$pass2 = Security::decrypt($pass, $key);
print_r($pass2);
//123456

 

2：JAVA加密

 

package com.zyd.blog.util;

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import org.apache.commons.codec.binary.Base64;


public class AES1 {

    /**
     * 加密
     * @param sSrc
     * @param sKey
     * @return
     * @throws Exception
     */
    public static String Encrypt(String sSrc, String sKey) throws Exception {
        if (sKey == null) {
            System.out.print("Key为空null");
            return null;
        }
        // 判断Key是否为16位
        if (sKey.length() != 16) {
            System.out.print("Key长度不是16位");
            return null;
        }
        byte[] raw = sKey.getBytes("utf-8");
        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");//"算法/模式/补码方式"
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
        byte[] encrypted = cipher.doFinal(sSrc.getBytes("utf-8"));

        return new Base64().encodeToString(encrypted);//此处使用BASE64做转码功能，同时能起到2次加密的作用。
    }

    /**
     * 解密
     * @param sSrc
     * @param sKey
     * @return
     * @throws Exception
     */
    public static String Decrypt(String sSrc, String sKey) throws Exception {
        try {
            // 判断Key是否正确
            if (sKey == null) {
                System.out.print("Key为空null");
                return null;
            }
            // 判断Key是否为16位
            if (sKey.length() != 16) {
                System.out.print("Key长度不是16位");
                return null;
            }

            byte[] raw = sKey.getBytes("utf-8");
            SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");

            cipher.init(Cipher.DECRYPT_MODE, skeySpec);
            byte[] encrypted1 = new Base64().decode(sSrc);//先用base64解密
            try {
                byte[] original = cipher.doFinal(encrypted1);
                return new String(original,"utf-8");
            } catch (Exception e) {
                System.out.println(e.toString());
                return null;
            }
        } catch (Exception ex) {
            System.out.println(ex.toString());
            return null;
        }
    }
}

 

使用

    @GetMapping("/encrypt")
    @BussinessLog(value = "加密测试", platform = PlatformEnum.WEB)
    public ResponseVO encrypt() {
        try {

            /*
             * 此处使用AES-128-ECB加密模式，key需要为16位。
             */
            String cKey = "root:123456789as";
            // 需要加密的字串
            String cSrc = "123456";
            System.out.println(cSrc);
            // 加密
            String enString = AES1.Encrypt(cSrc, cKey);
            System.out.println("加密后的字串是：" + enString);

            // 解密
            String DeString = AES1.Decrypt(enString, cKey);
            System.out.println("解密后的字串是：" + DeString);

        } catch (Exception e) {
            return ResultUtil.error(e.getMessage());
        }
        return ResultUtil.success("");
    }
