RSA-MFC,基于MFC的RSA加密算法的实现，可以用于16进制文件的加解密(RSA-MFC, the MFC based on the realization of RSA encryption algorithm, can be used for 16-band file encryption and decryption)

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.

VB程序注册机范例，控件简单实用，采用流行且难以破解的算法加密机器码、序列号、注册码，能更好地保护您的软件(VB program RI example, the controls simple and practical, using the popular and difficult to machine code to crack the encryption algorithms, serial numbers, registration codes, can better protect your software)

本文使用ECC加密AES的密钥，再由AES加密明文内容，AES加密强度大，速度快，但是密钥更新繁琐和不安全，由强度很大的非对称密钥算法对AES密钥加密，结合了两方的优点(this programme combine the ECC with AES.using the ECC to cipher the AES key,and using the AES to cipher the m)
