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.

破解VI的密码,两种方法可用,MD5算法(Two methods for password crack of vi)

一个非常好的ASE代码，通过实验证明能编译通过-A perfect AES program code, and it can be run after translation and edition.

关于Diamond算法的一个小程序-Diamond algorithm on a small program

说明：  配置 miracl 库，熟练调用 miracl 函数库，特别是其中的椭圆曲线运算相关函数对大数进行运算。学习并掌握 SM2 椭圆曲线公钥密码算法，开发 C 语言程序实现对消息的 SM2 加密和解密。(Configure the miracl library, skillfully call the miracl function library, especially the elliptic curve operation related functions to operate on large numbers. Learn and master SM2 elliptic curve public key cryptography algorithm, develop C language program to realize SM2 encryption and decryption of messages.)

收集汇总了网上的一维和二维FRFT ，提出一种2DFRFT和仿射置乱的图像加密方法(Collect aggregate online one-dimensional and two-dimensional FFT Proposed 2DFRFT and affine image scrambling encryption method)

本代码实现了playfair加密方法的变种，手动输入一个密钥和一串需要加密的字符串，解密的时候，则输入密钥和已加密的字符串，即加密解密是一个程序。详细请看代码。(This code implements a variant of the playfair encryption method to manually enter a key and a string of encrypted string decryption, enter the key and the encrypted string, that is, encryption decryption is a program. Look at the code in detail.)

一些常用的方法，很不错的实例，可以拿来学习，很不错哟-Some commonly used method, it is a good example, can be used to study, very good yo
