Description: 程序采用当前最先进的Rijndael算法作为核心算法，带有可变块长和可变密钥长度的迭代块密码。块长和密钥长度可以分别指定成 128、192 或 256 位。假设一台一秒内可找出DES密钥的机器(如，每秒试255个密钥)，如果用它来找出Rijndael的密钥，大约需要149万亿年。程序内部还使用了其它算法和符合密钥学的数据结构。多线程操作，保证加密时程序界面流畅,程序是用VS2005,C#做的，现将源程序发布在此。供初学者学习，希望对大家有所帮助。-procedures using the most advanced as a core Rijndael algorithm, with variable block length and variable length of the key block iterative password. Block length and key length can be designated as bit or 256. A second assumption Taiwan can identify with the DES key machines (for example, 255 per second key test), if it is used to identify the key Rijndael, approximately 149 Letters. Internal procedures are also used with other key algorithm and data structure of school. Multithreading operation to ensure that encryption program interface and smooth procedure is hashed, C# done. now source release here. For beginners learning, we hope to help.

Description: rc5]RC5 encryption algorithm Plug-in
In fact, RC5 algorithm with a variety of methods can be used a variety of programming languages, but the majority of books on cryptography algorithm RC5 briefly introduced in the comparison, and is more than its C language algorithms, and as a popular development tools, Visual Studio.Net framework Although System.Security.Crytography Namespaces provide a lot of encryption functions, such as DES, Rijndael, RC2, RSA and MD5, but did not provide RC5 algorithm!

Description: 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.
