AES加解密

1,Java端(依赖 common-codec jar)

package com.jiaMi;

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

import org.apache.commons.codec.binary.Base64;


public class AESUtils {

    private final static String KEY="1234123412341324";
    private final static String IV="1234123412341234";

    /**
     * aes 加密
     * @param data
     * @return
     */
    public static String encryptData(String data){
        try {
            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 String(Base64.encodeBase64(encrypted));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }


    /**
     * aes 解密
     * @param data 密文
     * @return
     */
    public static String decryptData(String data){
        try {
            byte[] encrypted1 =Base64.decodeBase64(data.getBytes());
            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;
    }


    public static void main(String[] args) {
        String data="php和java互通!";
        String enStr=AESUtils.encryptData(data);
        System.out.println("加密:"+enStr);
        String deStr=AESUtils.decryptData(enStr);
        System.out.println("解密:"+deStr);
    }

}

2,php 端

<?php
 $privateKey = "1234123412341324";
 $iv    = "1234123412341324";
 $data  = "测试用的数据";

 //加密
 $encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);
 echo(base64_encode($encrypted));
 echo '<br/>';

 //解密
 $encryptedData = base64_decode(base64_encode($encrypted));
 $decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $privateKey, $encryptedData, MCRYPT_MODE_CBC, $iv);
 echo($decrypted);
?>

3,js端

 <script src="./crypto-js.js"></script>
 <script src="./aes.js"></script>
 <script src="./pad-zeropadding.js"></script>
 <script>
var data = "测试用的数据";
var key  = CryptoJS.enc.Latin1.parse('1234123412341324');
var iv   = CryptoJS.enc.Latin1.parse('1234123412341324');

//加密
var encrypted = CryptoJS.AES.encrypt(data,key,{iv:iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.ZeroPadding});


//alert(encrypted);

   console.log(encrypted.toString());

//解密
var decrypted = CryptoJS.AES.decrypt(encrypted,key,{iv:iv,padding:CryptoJS.pad.ZeroPadding});
console.log(decrypted.toString(CryptoJS.enc.Utf8));

//alert(decrypted.toString(CryptoJS.enc.Utf8));
lt;/script>
