snail007 / nodejs javascript aes cbc zeropadding 128 的实现
Created May 2, 2017 09:33
nodejs javascript aes cbc zeropadding 128 的实现,"加密密码"和"加密向量"使用了md5("密码")的前16位. 使用的类库是CryptoJS
nodejs的实现:
var CryptoJS = require("crypto-js");
var password="password123";
var key,iv;
key=iv=CryptoJS.enc.Utf8.parse(CryptoJS.MD5(password).toString().substring(0,16));
//加密
var encrypted = CryptoJS.AES.encrypt('123中文',key,{iv:iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.ZeroPadding});
console.log(encrypted.ciphertext.toString());

php aes cbc zeropadding 128 的实现,原理是首先使用NoPadding然后自己对内容进行\0填充."加密密码"和"加密向量"使用了md5("密码")的前16位.
<?php
function openssl_aes_cbc_zeropadding_128_encrypt($msg, $key, $iv) {
$msgLength = strlen($msg);
$blockSize = 16;
if ($msgLength % $blockSize != 0) {
$msg .= str_repeat("\0", $blockSize - ($msgLength % $blockSize));
}
return bin2hex(openssl_encrypt($msg, 'AES-128-CBC', $key, OPENSSL_NO_PADDING, $iv));
}

linux下virtualbox无法识别usb解决办法
1.需要安装VirtualBox Extension Pack,下载地址https://www.virtualbox.org/wiki/Downloads
2.添加当前用户到组,执行sudo usermod -a -G vboxusers $USER
3.重启linux系统
4.在虚拟机的usb里面启用usb2.0
5.启动虚拟机,然后查看右下角usb标签,就会发现识别了usb设备.

固定wlan设备的名称
在/etc/udev/rules.d/目录下找到70-persistent-net.rules这个文件(没有则新建)，
在文件末尾添加
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="b8:27:eb:d6:74:00", NAME="wlan0"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="f0:b4:29:36:07:26", NAME="wlan1"
将其中的ATTR换位你的硬件MAC地址
NAME就是设备名。
