一个简单的cpp程序,接收一个文件,没有一点
A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file.
The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.

md5--加密文件
MD5 算法描述 对 MD5 算法简要的叙述可以为:MD5 以 512 位分组来处理输入的信 息,且每一分组又被划分为 16 个 32 位子分组,经过了一系列的处理后, 算法的输出由四个 32 位分组组成, 将这四个 32 位分组级联后将生成一个 128 位散列值。 在 MD5 算法中,首先需要对信息进行填充,使其字节长度对 512 求 余的结果等于 448。因此,信息的字节长度(Bits Length)将被扩展至 N*512+448,即 N*64+56 个字节(Bytes) ,N 为一个正整数。填充的方 法如下,在信息的后面填充一个 1 和无数个 0,直到满足上面的条件时才 停止用 0 对信息的填充。 请点击左侧文件开始预览 !预览只提供20%的代码片段,完整代码需下载后查看 加载中 侵权举报
