在c#中调用windows API

将MEMS传感器传回的数据做处理，主要是找到起始位、提取数据位、分割出每轴相应数据、16进制转换为10进制、输出数据到excel表格，方便matlab使用。程序用C语言编写，思路清晰，注释清楚，可以运行。

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.
