大整数运算的实现-large integer arithmetic Implementation

AES implementation in C++. Input: key file and the file for encryption Output: the crypted file.

这个小软件通过在可执行文件(.exe)的尾部添加一个新节(Section)，并且修改PE的入口地址，使可执行文件在运行时，跳出一个输入密码的对话框，从而实现了简单的加密。-small software in executable files (. Exe) to the tail adding a new section (Section), and amend the PE import addresses, so that the executable file is run, jump out of a password dialog box, thus achieving a simple encryption.

RSA算法的C++实现。公钥加密算法中使用最广的是RSA。RSA算法研制的最初理念与目标是努力使互联网安全可靠，旨在解决DES算法秘密密钥的利用公开信道传输分发的难题。-RSA algorithm is the C++ implementation. Public key encryption algorithm is the most widely used is RSA. RSA algorithm is developed by the original idea and objective is to make the Internet safe and reliable, aimed at resolving the DES algorithm is a secret key transmitted using the open channel distribution problems.
