前端代码:
<script type="text/javascript" src="js/jquery-3.3.1.js"></script> <script type="text/javascript" src="js/CryptoJS/rollups/aes.js"></script> <script type="text/JavaScript"> function userlogin(){ var userName = $("#username").val(); //密钥 (需要前端和后端保持一致)十六位作为密钥 var key = "ABCDEFGHIJKL_key"; //密钥偏移量 (需要前端和后端保持一致)十六位作为密钥偏移量 var iv = "ABCDEFGHIJKLM_iv"; //获取加密后的密码 var password = aesMinEncrypt(key,iv,$("#password").val()); alert("加密后的密码为:"+password); $.ajax({ url: "userlogin", async:false, type: "POST", data: {'userName':userName,'password':password}, success: function (result) { $("html").html(result); } }); } 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(); } </script>
后端代码:
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); } }
2.项目中引用该刚发方法中的解密部分:
3. 实测结果:
用 userName:admin ; password:admin12346进行测试
