AES_CMAC
通过C语言实现的AES CMAC加密和解密算法。上传文件为完整的VC6工程目录。AES加密算法即密码学中的高级加密标准(Advanced Encryption Standard,AES),又称Rijndael加密法,是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES,已经被多方分析且广为全世界所使用。经过五年的甄选流程,高级加密标准由美国国家标准与技术研究院 (NIST)于2001年11月26日发布于FIPS PUB 197,并在2002年5月26日成为有效的标准。AES 算法基于排列和置换运算。排列是对数据重新进行安排,置换是将一个数据单元替换为另一个。AES 使用几种不同的方法来执行排列和置换运算。 AES 是一个迭代的、对称密钥分组的密码,它可以使用128、192 和 256 位密钥,并且用 128 位(16字节)分组加密和解密数据。与公共密钥密码使用密钥对不同,对称密钥密码使用相同的密钥加密和解密数据。通过分组密码返回的加密数据的位数与输入数据相同。迭代加密使用一个循环结构,在该循环中重复置换和替换输入数据。(AES CMAC encryption and decryption algorithm C language. VC6 upload files to complete the project directory . AES encryption algorithm that is Cryptography Advanced Encryption Standard (Advanced Encryption Standard, AES), also known as Rijndael encryption method, a block encryption standard adopted by the U.S. federal government . This standard is used to replace the original DES, has been widely analyzed and multi used around the world . After five years of the selection process , the Advanced Encryption Standard by the American National Institute of Standards and Technology (NIST) on November 26, 2001 Posted in FIPS PUB 197, and May 26, 2002 became effective standards . AES algorithm based on permutation and substitution operations. Data re- arrangement is arranged , is replaced with a replacement unit of data to another . AES using several different methods to perform alignment and replacement operations. AES is an iterative , symmetric key block password , it can use 128, 192, and )

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)

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:)

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)

SM3,SM4_UI
将国密算法SM3, SM4 ECB的C代码打包成dll库。
然后在C#中进行调用。
有输入输出接口,测试结果正确。
包含所有源代码,可在此基础上进一步开发(The C code of the Chinese national algorithm SM3, SM4 ECB is packaged into a dll library and then called in C# with input and output interfaces. The test result is correct. Contains all source code and can be further developed on this basis)
