crypto-js RSA AES 加解密方法-----------

时间：2025-01-20 20:28:42

crypto-js的加解密使用方法

  • rsa 公私钥加解密
  • aes 随机字符加解密（mode:）
  • 也可以参考[JavaScript前端和Java后端的AES加密和解密](/web-chuanfa/p/)
    • 扫码体验 虚拟电话小程序

rsa 公私钥加解密

  /* * 加密（需要先加载/aes.min.js文件）
RASkey=‘XXXXXXXXXXX’//这个是公钥   后端生成 或者前端自己用方法生成   前端只能纯公钥
function Encrypt(){
  var encrypt=new JSEncrypt();
  encrypt.setPrivateKey(RASkey);
  let data =encrypt.encrypt(‘123456789ABCDE’)
	return data;
}

aes 随机字符加解密（mode:）

/**  写法有很多  这里是博主目前自己用的第一个  真实有效 
 * 加密（需要先加载lib/aes/aes.min.js文件）
*  key也可以使用随机数  方法如下
*  随机16位密钥
   function getAesKey(len) {
     len = len || 16;
     var $chars = '12345678ABCDEFGH';//可以自己随便定义
     var maxPos = $chars.length;
     var keyStr = '';
     for(let i = 0; i < len; i++) {
         keyStr += $chars.charAt(Math.floor(Math.random() * maxPos));
     }
     return keyStr;
   }
