springboot接口验签，前后端加解密（基于hutool）、c#、vue、js的aes指定秘钥加密(前后端aes加解密)
gitee源码地址：https://gitee.com/huangtao_2021/springboot-encrypt.git，加解密基础上增加了接口注解验签功能，c#、vue、js版本的代码放在项目路径下/src/main/java/resources文件夹中
一、后端java
//aes加密,输出16进制
String jsondata = SecureUtil.aes("._^BV67nW6ck8fwg".getBytes()).encryptHex(obj);
System.out.println(jsondata);
//aes解密密,输出16进制
String decryptStr = SecureUtil.aes("._^BV67nW6ck8fwg".getBytes()).decryptStr(jsondata);
System.out.println(decryptStr);

二、后端c#

三、前端vue
utils文件夹下新建encryp.js
import CryptoJS from 'crypto-js'
// 加密
export default {
encrypt(word, keyStr, iv) {
let keys = CryptoJS.enc.Utf8.parse(keyStr); //'82LIb3DQE9ByIdz9'
let ivs = CryptoJS.enc.Utf8.parse(iv); //iv '0102030405060708'
let srcs = CryptoJS.enc.Utf8.parse(word);
let encrypted = CryptoJS.AES.encrypt(srcs, keys, {
iv: ivs,
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
});
console.log("base64:" + encrypted);
var encryptedStr = encrypted.ciphertext.toString();
console.log("16进制:" + encryptedStr);
return encrypted.ciphertext.toString(); //16进制
// return encrypted.toString(); //base64
},
// }
// 解密
decrypt(word, keyStr, iv) {
// ********************解密16进制***********************
let key = CryptoJS.enc.Utf8.parse(keyStr); //'82LIb3DQE9ByIdz9'
let ivs = CryptoJS.enc.Utf8.parse(iv); //'0102030405060708'
let encryptedHexStr = CryptoJS.enc.Hex.parse(word);
let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
let decrypt = CryptoJS.AES.decrypt(srcs, key, {
iv: ivs,
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
});
let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
console.log(decryptedStr)
return decryptedStr.toString();
}
}
使用
import Crypto from "@/utils/encryp.js"; //很多页面要使用时也可以再main.js中定义：import Crypto from "@/utils/encryp.js";Vue.prototype.$crypto = Crypto; 页面中调用： var t = $crypto.encrypt('中国test',"._^BV67nW6ck8fwg","");
var encode = Crypto.encrypt('中国test',"._^BV67nW6ck8fwg","");
console.log("加密后："+encode);
var decode = Crypto.decrypt('4aeb52befdb579c52889cb5e9678bea5',"._^BV67nW6ck8fwg","");
console.log("解密后："+decode);
需要下载CryptoJS库，下载地址如下：
https://github.com/sytelus/CryptoJS
需要引入库文件：
<script src="./CryptoJS-master/rollups/aes.js"></script>
<script src="./CryptoJS-master/components/mode-ecb.js"></script>
<script src="./CryptoJS-master/components/pad-nopadding.js"></script>
以下是完整的Demo代码：

}
function decryptText() {
var encrypted = document.getElementById("todecrypt").value;
console.log("encrypted: " + encrypted);
var decrypted = decrypt(encrypted);
console.log("decrypted: " + decrypted);
document.getElementById("decrypted").value = decrypted;
}
// 加密方法
// data：要加密的字符串

function encrypt(data) {

var iv = CryptoJS.enc.Utf8.parse(ivinit); // 偏移量

var encrypted = CryptoJS.AES.encrypt(str, key,
{
iv:iv,
mode:CryptoJS.mode.ECB, // AES加密模式
padding:CryptoJS.pad.Pkcs7 // 填充: pkcs7 padding
}).ciphertext.toString(); // 输出字符 hex
return encrypted;
}
// 解密方法

const decrypted = CryptoJS.AES.decrypt(str, key,
