Hash_sha256
sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现
依次执行
SHA256Init、
SHA256Update
SHA256Final
三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

ECC
椭圆曲线的实现(ECC)，椭圆曲线算法是代数几何、数论等多个数学分支的一个交叉点，一直被人们认为是纯理论学科。而椭圆曲线密码体制，是基于椭圆曲线离散对数问题的一种公钥密码体制(Realization of elliptic curves (ECC), elliptic curve algorithm is algebraic geometry, a number of mathematical intersection of number theory and other branches, has been considered a purely theoretical discipline. The elliptic curve cryptosystem is based on elliptic curve discrete logarithm problem as a public-key cryptosystem)

ASFDSAF
题目：某个公司采用公用电话传递数据，数据是四位的整数，在传递过程中是加密的，加密规则如下：
每位数字都加上5,然后用和除以10的余数代替该数字，再将第一位和第四位交换，第二位和第三位交换。
1.程序分析：
2.程序源代码：(Topic: a company USES the public telephone relay data, data is four integers, in the relay in the process is encrypted, encryption rules are as follows:
Each Numbers add 5, then use and divided by the number of 10 instead of a remnant, then the first and fourth exchange, the second and third exchange.
1. The program analysis:
2. The source code:)
