在工作中经常遇到密码明文传输这个问题,为了让密码安全些会让加密,现在有个比较方便的AES加密(前端密钥可能存在泄露风险,应该放到配置项中):
CryptoJS-v4.1.1

function register() { var password = $.common.trim($("input[name='password']").val()); //AES加密 var key = "ABCDEFGHIJKL_key"; var iv = "ABCDEFGHIJKLM_iv"; var encryptedPwd = aesMinEncrypt(key,iv,password); $.ajax({ type: "post", url: ctx + "register", data: { "password": encryptedPwd, ... ... } success: function (res) {} }); } function aesMinEncrypt(key, iv, word){ var _word = CryptoJS.enc.Utf8.parse(word), _key = CryptoJS.enc.Utf8.parse(key), _iv = CryptoJS.enc.Utf8.parse(iv); var encrypted = CryptoJS.AES.encrypt(_word, _key, { iv: _iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); return encrypted.toString(); }
后端解密需要用到一个工具类:AESUtils,里面是解密方法代码如下:
package com.wuye.common.utils; import cn.jpush.api.utils.StringUtils; import sun.misc.BASE64Decoder; import javax.crypto.Cipher; import javax.crypto.spec.IvParameterSpec; import javax.crypto.spec.SecretKeySpec; /** * TODO * * @author CSD * @date 2022-07-28 14:16 */ public class AESUtils { //密钥 (需要前端和后端保持一致)十六位作为密钥 private static final String KEY = "ABCDEFGHIJKL_key"; //密钥偏移量 (需要前端和后端保持一致)十六位作为密钥偏移量 private static final String IV = "ABCDEFGHIJKLM_iv"; //算法 private static final String ALGORITHMSTR = "AES/CBC/PKCS5Padding"; /** * base 64 decode * @param base64Code 待解码的base 64 code * @return 解码后的byte[] * @throws Exception */ public static byte[] base64Decode(String base64Code) throws Exception{ return StringUtils.isEmpty(base64Code) ? null : new BASE64Decoder().decodeBuffer(base64Code); } /** * AES解密 * @param encryptBytes 待解密的byte[] * @return 解密后的String * @throws Exception */ public static String aesDecryptByBytes(byte[] encryptBytes) throws Exception { Cipher cipher = Cipher.getInstance(ALGORITHMSTR); byte[] temp = IV.getBytes("UTF-8"); IvParameterSpec iv = new IvParameterSpec(temp); cipher.init(Cipher.DECRYPT_MODE, new SecretKeySpec(KEY.getBytes(), "AES"), iv); byte[] decryptBytes = cipher.doFinal(encryptBytes); System.out.print(new String(decryptBytes)); return new String(decryptBytes); } /** * 将base 64 code AES解密 * @param encryptStr 待解密的base 64 code * @return 解密后的string * @throws Exception */ public static String aesDecrypt(String encryptStr) throws Exception { return StringUtils.isEmpty(encryptStr) ? null : aesDecryptByBytes(base64Decode(encryptStr)); } //测试一下 public static void main(String[] args) throws Exception { String str = "Q uus tQvLdwtGSldhrtKQ=="; str = str.replace(" ", "+"); System.out.println(str); aesDecrypt(str); } }
String decrypassword = AESUtils.aesDecrypt(password);
