记登录注册时候 前端js明文密码 加密传输 php解密

前端 使用key iv 使用aes加密后字符串传给后台  (可拼接时间戳加密)

        function js_encrypt(text){
            var key = CryptoJS.enc.Latin1.parse('1E390CMD585LLS4S'); //为了避免补位,直接用16位的秘钥
            var iv = CryptoJS.enc.Latin1.parse('1104432290129056'); //16位初始向量(请记住这两个都要保证是16位)
            var encrypted = CryptoJS.AES.encrypt(text, key, {
                iv: iv,
                mode:CryptoJS.mode.CBC,
                padding:CryptoJS.pad.ZeroPadding
            });
            return encrypted;
        }

后台 解密

        $password = input('password');
        $password_dec=iconv('utf-8','gbk',js_decrypt_openssl($password));
        $timesm=substr($password_dec,-10);
        $password = str_replace($timesm,'',$password_dec);
        if(time() > $timesm + 10){
               $errcode = 10006;
            return json(['errcode'=>$errcode,'errmsg'=>errcode::getErrMsg($errcode)]); 
        }


function js_decrypt_openssl($encrypt){
    $key = "****"; //与JS端的KEY一致
    $iv = "****"; //这个也是要与JS中的IV一致
    $decrypted = openssl_decrypt($encrypt, 'AES-128-CBC', $key, 2 , $iv);
    $decrypted = trim(trim($decrypted, "\0000"),'');//这个一定要有,要不然在你不用浏览器查看源代码的情况下是很难发现,还有一些乱码存在的
    return $decrypted;
}
