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:)

sha256
SHA-256源代码,三个对外的函数:void SHA256Init (SHA256Context *sc)
void SHA256Update (SHA256Context *sc, const void *data, uint32_t len)
void SHA256Final (SHA256Context *sc, uint8_t hash[SHA256_HASH_SIZE])
第一个函数初始化,第二个函数输入要hash的字符串,第三个函数输出结果(SHA-256 source code, three external function: void SHA256Init (SHA256Context* sc) void SHA256Update (SHA256Context* sc, const void* data, uint32_t len) void SHA256Final (SHA256Context* sc, uint8_t hash [SHA256_HASH_SIZE]) The first function is initialized, the second hash function, enter the string, the third function of output)

看到RSA加密的C++类下载的人不少,我也下载了,并且稍微改动了一下,使它看上去更加易懂。在新年随手写了一套RSA文件加密,用win32dll封装使用了这个类,用C#写了文件加密和操作界面,可以实现密钥的保存和对任何文件的RSA加密操作。送给大家祝大家新年快乐。(see RSA encryption C downloaded to many people, I have downloaded and slightly altered a bit it looks more comprehensible. New Year threw in a written document RSA encryption, win32dll Compliant with the use of this category, C# to write document encryption and interface, can achieve key to the preservation of any documents and the RSA encryption operation. Give you wish you a happy New Year.)

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)
