验证签名 x.509 证书没有 openssl

该程序是使用恺撒密码和transposotion密码。也许这个计划太简单了，但总比没有强。：V

CRC算法与C语言

有些还是很有用的，网络验证经常能用到的，直接将cpp文件加入到工程里就可以了---Can realize analog keyboard, driver class. Like an ordinary keyboard can be used

文件加密，可以对任意文件进行加密-file encryption, to arbitrary files can be encrypted

该源码描述了DES加密算法的硬件语言实现方式-The source described the hardware DES encryption algorithm realize the way language

AES Rijndael fast security system to encrypt and deycrypt information

MD5算法的实现。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。 -MD5 algorithm. MD5 to 512 groups to deal with the importation of information and each group was also divided into 16 groups of 32 seats, After a series of processing, the output from the algorithm 4 32 subgroups, 4 32 this group will generate a cascade 128 hash value.

在不改变access文件密码的情况下，直接查看密码，数据库内容一览无余哦！-Without changing the password access documents directly view the password, database content glance Oh!

多数程序设计语言处理整数的能力是有限的，如C语言中，int类型数据范围是-32767----32767。实际问题的处理过程中往往涉及大整数的运算，如RSA加密算法要求至少64bit的整数，本程序是设计算法实现大整数的加减运算。-majority programming language processing is integral to the limited capacity, such as C language, int data type is the scope-32767---- 32767. Practical problems of the treatment process often involves large integer arithmetic, such as the RSA encryption algorithm requires at least 64-bit integers, the procedure is designed algorithm large integer addition and subtraction operations.
