bugscan泄露代码解密的相关文章

从B站的代码泄露事件中，我们能学到些什么？

先声明一下,本文不聊ISSUE中的七七八八,也不聊代码是否写的好,更不聊是不是跟蔡徐坤有关之类的吃瓜内容.仅站在技术人的角度,从这次的代码泄露事件,聊聊在代码的安全管理上,通常都需要做哪些事来预防此类事件的发生.同时,大家在阅读本文的时候,也可以深入思考下,自己团队是否也存在类似的问题,经过这次的事件,是否有必要针对性的做一些优化. 最小权限 "最小权限"原则是我们在学习Linux用户管理时候经常被提到,并且被反复强调的内容.该原则是指每个程序和系统用户都应该具有完成任务所必需的最小权

C# 加密–RSA前端与后台的加密&解密

1. 前言本问是根据网上很多文章的总结得到的. 2. 介绍 RSA加密算法是一种非对称加密算法. 对极大整数做因数分解的难度决定了RSA算法的可靠性.换言之,对一极大整数做因数分解愈困难,RSA算法愈可靠.假如有人找到一种快速因数分解的算法的话,那么用RSA加密的信息的可靠性就肯定会极度下降.但找到这样的算法的可能性是非常小的.今天只有短的RSA钥匙才可能被强力方式解破.到2016年为止,世界上还没有任何可靠的攻击RSA算法的方式.只要其钥匙的长度足够长,用RSA加密的信息实际上是不能被解破的

关于java加壳和代码混淆

关于java加壳和代码混淆在C中,进行代码加密,首要经过加壳的方法.所谓加壳,即是先将程序代码加密,然后用特定的程序加载器,将代码解密后加载进内存,这样能够在避免代码的反编译,当然,有加壳东西,也有解壳东西,尽管不能100%避免crack,但仍然给代码增加一层有力的维护. 然而在Java中,维护代码是件很困难的工作,由于class文件十分标准,很容易反编译,且反编译后的代码明晰可读.常见的维护办法是运用代码混淆器,打乱class和function以及变量的姓名,能够搅扰反编译后的代码的可读性.

被用坏的DexClassLoader，关于DexClassLoader内存泄露的问题

原因: 目前有两种猜测,第一种就是类加载容易,但是类卸载就不那么容易了,第二种猜测就是类缓存机制,从classloader的运行过程可以分析到有个过程是缓存常用类的,感觉这个过程没法释放,因为他会认为你以后会一直用. 测试内存泄露代码: 可以用DDMS测试下,当你调用GC的时候byte是可以回收的,但是classloader就没法回收了,也许你认为是因为调用了activity的classloader造成的,但是回头想想这个classloader可是整个应用的,除非你关闭应用,否则无法去掉clas

vs2010使用vld检测内存泄露

cocos2d-x不仅可以做到跨平台运行,还可以做到跨平台编译调试(当然只是编译对应平台下的应用了).众所周知,cocos2d-x是用c++编写的,而c++中最让人头疼的莫过于指针和内存泄露的问题,在windows下,cocos2d-x支持在vs下开发,这样,平时写win32项目的开发工具就可以用在cocos2d-x开发上了,善哉!今天就介绍一个检测内存泄露的工具,Visual Leak Detector,简称 vld 1.安装这一步很简单,官网已经在上面给了,直接download吧,跳过!
