C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

可以对文件进行加解密，这是自己编写的实验作业(Can encrypt and decrypt files, it is their job to prepare experimental)

本程序是仿射密码的加密与解密，用C语言编写的，经测试没有问题(This procedure is affine password encryption and decryption, written in C, tested no problem)

本文使用ECC加密AES的密钥，再由AES加密明文内容，AES加密强度大，速度快，但是密钥更新繁琐和不安全，由强度很大的非对称密钥算法对AES密钥加密，结合了两方的优点(this programme combine the ECC with AES.using the ECC to cipher the AES key,and using the AES to cipher the m)

无须解压密码,利用自己设计的程序同样可以实现对控制面板内容的控制,(Do not need to unzip password, to use its own design program can also realize the control of the content of the control panel,)

说明：  信息安全相关，经典加密算法A5，通过编译(Information security-related, classic encryption algorithm A5, through compiler)

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

playfair 加密算法的实现，用一个例子做了展示(realize playfair algorithm，use a sample to show the algorithm)

MD5是一种被广泛使用的“消息-摘要算法”。实际上就是一个单项散列函数。(MD5 is a widely used " message- digest algorithm." Is actually a single hash function.)
