rc4+ctf常用编码加密shellcode ctfexepyinstallerpython3string 本文不会解释rc4加密是什么,以及ctf编码在我的理解中为一个大类,并非单独一种编码形式,当然不管是rc4还是ctf编码,其宗旨都是为了使字符串变得“毫无意义”从而达成无法被杀软正确的检查出是shellcode。其实这篇文章更多的算是踩坑记录,因为本身代码的实现...
Python 实现RC4加解密 核心原理如下: 导入包ARC4 其中Crypto如果没有可以网上搜索安装 主要就是利用ARC4的new(传入key) 返回一个rc4对象 rc4对象在调用加密或者解密函数. 注意key必须是 bytes类型.如果不是要转换为bytes 对于base64编码过的程序请先解码.然后再用 代码如下: 代码语言:javascript 代码运行次数:0 ...

介绍 在密码学中，RC4（Rivest Cipher 4，也称为ARC4或ARCFOUR，意为所谓的RC4）是⼀种流密码。尽管它以简单性和软件速度着称，但在RC4中发现了多个漏洞，使其不安全。当不丢弃输出密钥流的开头或使⽤⾮随机或相关密钥时，它特别容易受到攻击。RC4的使⽤特别有问题，导致协议⾮常不安全，例如WEP。参数...
